What is sandblasting room, how it works?

Sandblasting room is also called air blasting booth, abrasive blasting room. It is suitable for clean the oxide scale, rust and coating of medium structure parts, irregular parts and batch processing parts surface, which can increase the adhesion between the workpiece and coating.

The sandblasting room is powered by air compressed, which can make the abrasive and compressed air fully mixed.  After speed up via the venturi nozzle, the abrasive and air mixture spray to the metal surface with the high speed to clean the oxide scale, rust and oil, so that achieve to the process requirements. In the rust removal progress it will have a large amount of dust and the sprayed abrasive will splash around. So the entire sandblasting progress need to be carried out in a closed space with negative pressure.

Features of sandblasting room

  1. The sandblasting room can be designed by customers requirements and workpiece characteristics. There is no need to dig the complex foundations, it can greatly save the construction cost;
  2. The sandblasting room have its own abrasive reclaim system, so it can not jam abrasive in the reclaim system. It not only have high recovery rate but also have high abrasive utilization rate;
  3. The mainly electric components are all use well-known brand at home and abroad, which have stable performance, long service life and simple maintenance and other advantages;
  4. The sandblasting room chamber have high definition visibility, the inlet opening adopt the naturally replenishes the air and save a part of the energy consumption;
  5. The sandblasting room adopt two-stage dust removal, the first stage is use the settling chamber to separate the big particles and dust, the second stage use the filter cartridge to filter the dust. So that the cleaning efficiency can up to 99.5%.

Working principle of sandblasting room

Before the sandblasting, we need to do some preparation works. Such as move the workpiece into the sandblasting room chamber, connect the electric and pneumatic control device, turn on the lights, wear the protective clothes and turn on the ventilation device on the helmet.

Then close the doors, hold the sandblasting gun, open the switch and clean the workpiece. The used abrasive will fall into the reclaim system, then through the screw or scraper transport the abrasive into the bucket elevator. Via the air-wash separator, the abrasive, broken abrasive, the rust slag and dust will be separated.

The qualified abrasive will directly into the storage silo to recycle to use, the broken abrasive and the rust slag will fall into the waste box. The dust will be sucked away by the dust collector and absorbed on the surface of the filter cartridge. The pulse valve of the dust collector will generate pulse signals to release the air compressed stored in the air bag regularly, and instantly form an expanding airflow to act on the inside of the filter cartridge. The dust adsorbed on the surface of the filter cartridge is shaken off and dropped into the lower dust collect box for regular cleaning.

Application industries of sandblasting room

Sandblasting rooms are widely used in casting, mould, steel, aerospace, aviation, shipbuilding, electromechanical, military industry, containers, railway locomotives and many automobile manufacturing industries.

Such as cleaning and strengthening of the surface of casting parts; cleaning and strengthening of fixtures and materials; surface cleaning of parts before electroplating, oxidation and painting; cleaning of contaminants on the surface of barrels, tubes, pans, tanks and utensils tools, molds, pipes, plates and cleaning of operating parts; surface cleaning of glass molds, rubber molds, metal castings and extrusions; trimming welds; removing oxide scale on the surface of the workpiece, and removing color difference during processing (castings, forgings); clean up large turbines, engine castings or complex small parts; clean up parts (such as cylinder blocks, pistons and spark plugs) during engine maintenance; remove the surface of the workpiece paint and dirt etc.

Construction of sandblasting room

Sandblasting room is mainly constructed of blasting room wall, door, lighting, material handling system, sandblasting machine and abrasive reclaim system.

Blasting room wall

The blast room walls are fabrication by sandwich panel with noise attenuation interlayer, which total thickness is 50mm. To prevent wear, the inside of the chamber adopts 5mm thick wear-resistant rubber guard board for protection. Each sandwich panel (2 meters) has a strong frame made from the square tube. This ensures they will not deformation during transportation and installation, the grinding and painted square tube will be far enough to be resistant the corrosion by the natural environment.

The dust removal tuyere set up on the principle of the “top feed, bottom suck, top emissions”, so that it can make the dust flow to the bottom as far as possible to increase the operator’s visibility.

Door

Sandblasting room doors have a variety of choices.

  1. Double swings door
  2. Roller shutter door
  3. Sliding door
  4. Access door

Depending on your requirements, you can choose to have only one door or two doors. A door workpiece enters the sandblasting room through this door and exits through this door. Two units doors is flow-through design with doors on both ends of the sandblasting room where objects enter from one end, and exit through the door. An exclusive sealing system prevents the loss of abrasive materials and makes the closing of the doors possible without effort.

Lighting

Design the number of lights according to the size of sandblasting room. Light fixtures use high efficiency LED lamps, which enables maximum utilization of the luminosity, to ensure the sufficient brightness in the room, and the indoor operator can clearly see the workpiece and the surface effect after blasting. The fastening system of the blasting room allows easy removal for maintenance.

what is sandblasting room 3

Material Handling System

One of the most important considerations when designing the sandblasting room is how the object items blasted are going to be moved in and out of the blast room.

These are some very important questions that need to be asked about material handling…

Every facility is different, if you are designing a new facility, you have one chance to get it right.

If upgrading an existing facility, you need to look at what material handling options will work

in with what I already have….There are many options and ways to move product through your

blast and paint area. When it comes to material handling, there are several options that can speed up moving objects in and out of the enclosure.

Forklift Transportation

Forklift transportation requires the floor of the blasting room to be level with the floor of the workshop to ensure that the forklift can enter the blasting room smoothly, so the blasting room needs to have a foundation pit.

Trolley (rails in the floor)

Trolley is also a great solution for heavier items. The objects to be blasted is placed on the trolley outside of the room and then get in to be blasted. The wheeled trolley stays in the room during blasting and can be mounted on tracks or rails when required.

Monorail

Monorail systems can be installed inside the blast room or outside with a brush seal providing containment of abrasive within the room. Monorails allow objects to be hang below them and moved in and out of the room and can be motorized.

what is sandblasting room 10

Sandblasting machine

According to the number of operators in the sandblasting room and requirements, customer can choose the size and number of sandblasting pot. QGMA sandblasting tank adopts manual remote control spray gun, and the operator controls the nozzle sand blasting or air injection. This can be used to remove floating ash from the working surface after blasting.

Boron carbide nozzle with high efficiency, good wear resistance, long life, strong injection force, to ensure uniform, high quality cleaning work.

The working process is as follows: power on, when the lower level gauge of the blasting machine touches the abrasive, the air intake of the tank is closed, and the blasting machine and air jet control system get the signal to start the operation. Once the lower level gauge cannot touch the shot material, the feeding mechanism starts to work. When the upper level gauge of the shot blasting touches the abrasive, the feeding mechanism stops working and the tank body is inflated and closed.

Abrasive reclaim system

Abrasive reclaim system including floor reclaim system, bucket elevator and air wash separator.

Abrasive from floor reclaim system into bucket elevator, then into the air wash cleaner system, and then the abrasive that can used into hopper then into abrasive dosing unit, can not used abrasive get out the reclaim system.

Floor recycling system

There are two types of floor recycling systems, pneumatic recycling and mechanical recycling. Pneumatic recovery, also known as honeycomb recovery, is completely absorbed from the ground to the separation by the fan. Mechanical recovery is a form of recovery of abrasive scattered on the ground into elevator by mechanical movement, now the most used is mechanical recycling.

According to requirements, there are 6 kinds of floor recycling systems to choose.

Sweep-In/ Shovel Chute Reclaim System

Sweep-in / shovel chute reclaim system is the basic and the most economical floor reclaim system.

The shovel chute is directly connected to the bucket elevator. After the work, the workers push the abrasive into the shovel, and then directly into the elevator, to achieve the purpose of recycling. More suitable for small size sandblasting room.

what is sandblasting room 6

Single screw partial reclaim system

Single screw partial reclaim system means is only one unit screw conveyor on the floor. According to the requirements, the position of the screw can be changed at will. This is the most affordable solution for small and medium-sized sandblasting rooms. The screw can be replaced with a scraper.

Located at the bottom of the cleaning room, when working, the screw conveyor rotates to transport the abrasive to the discharge port, and then flows into the bottom of the bucket elevator from the discharge port. The spiral blade is welded to the drive shaft, and the entire spiral shaft is processed as a whole after welding, thus ensuring the coaxiality of the spiral shaft. The inner and outer circles of the spiral blade are processed by a special process and then stretched. The pitch and outer circle dimensions are very accurate, which improves the life of the spiral.

The sealing of the bearing adopts labyrinth discs, bearing pads, etc., so as to better protect the bearing from damage due to the entry of shot sand, maximize the service life of the bearing, and reduce the maintenance cost of the equipment.

H shaped partial reclaim system

H shaped partial reclaim system is composed of one unit crosswise screw conveyor and two units scraper recovery system. Of course, the screw can be replaced with a scraper. What is scraper?

The scraper conveyor is composed of air cylinders, connecting rods, scrapers, rollers, etc. Simple structure, simple installation and maintenance, safe and reliable, long life, low maintenance cost. When the plate conveyor is working, the cylinder pushes the scraper assembly, and the scraper pushes the abrasive forward by one cylinder stroke under the action of the stopper. When the scraper returns to its original position, the scraper automatically tilts up and will not bring back abrasives. Improve transportation efficiency and reduce energy consumption.

The drive system uses a cylinder, which is stable and reliable, and has a low failure rate; the scraper adopts step-by-step propulsion, the material moves uniformly and reliably, and has low noise and long service life; the required foundation depth is very small, only 0.3-0.5 meters deep, which is greatly Reduce the cost of foundation production. It has incomparable superiority in resistance to harsh environments such as humidity.

what is sandblasting room 8

U shaped partial reclaim system

U shaped reclaim system is very similar with H shaped reclaim system, the different is the position of the screw conveyor.

H reclaim system the screw conveyor in the middle and U reclaim system the screw conveyor on either side.

what is sandblasting room 9

Full floor reclaim system

The full floor reclaim system utilizes one unit screw and multiple scraper recovery system assemblies to create a fully automatic, high volume abrasive reclaim system where 100% of the abrasive blast media is returned to the bucket elevator during the blasting operation. This abrasive blast reclaim system is well suited for pass-thru and/or high production requirements.

what is sandblasting room 5

The floor of the sandblasting room adopts a metal grille, which is conducive to the collection and discharge of steel grit on the one hand, and is conducive to the safety of workers walking on the other hand. In order to prevent large impurities and foreign bodies from entering the sandblasting tank through the conveyor during working hours, blocking the spray gun. This equipment is equipped with a filter in the lower part of the grille (floor recovery) to prevent impurities and foreign objects from entering. The cleaning of impurities and foreign objects is very convenient. You can completely clean up the grille laid on the floor inside the house, so as to ensure that the recycling pipe network can work smoothly for a long time. ;

The floor grille is welded with 40*4mm flat steel bars. The specific format and quantity are determined by the size of the house and the track spacing of the work trolley. Generally, the floor grid inside the sandblasting room has a bearing capacity of less than 200kg per square meter. If a larger floor grid bearing requirement is required, the customer needs to put forward special design requirements.

Bucket elevator

The bucket elevator is composed of a reducer, upper and lower pulleys, conveyor belts, buckets, closed shells and tensioning devices.

The bottom inlet of the bucket elevator is connected with the floor reclaim system, and the top outlet is connected with the air wash separator.

When working, the bucket fixed on the conveyor belt scrapes the steel shot at the bottom of the elevator, and then is driven by the elevator motor to send the steel shot to the top of the elevator, and finally fall down by centrifugal gravity, and the steel shot is input air wash separator.

Air wash separator

During the descending process of the mixture of steel shot and residue, it is pushed by the horizontal airflow to the particles, thereby forming a skewed curved trajectory. Due to the difference in the specific gravity and particle size of the particles, the degree of deflection is not the same, so that the steel shot and the The residue is separated, the dust is sucked into the dust collector for purification treatment, broken pellets, oxide skin, etc. enter the waste storage hopper, and qualified steel shots and some small debris are screened again into the storage hopper for recycling.

Dust removal system

As the dust extraction fan extracts the gas and dust in the blasting room, the airflow outside the blasting room enters the blasting room through the coarse filter on the top of the blasting room, and then enters the blasting room through the uniform flow plate on the top of the blasting room. In the sandblasting studio, a top-down airflow is formed in the cross-section of the sandblasting room, and the dust and dirt in the sandblasting room will enter the dust extraction port with the airflow, and finally enter the dust removal system through the dust removal pipe, and then pass through the dust removal system. The filtered, clean air is

discharged into the atmosphere, and the dust and dirt are stored in the dust cylinder for regular cleaning.

In the sandblasting room, the dust removal system adopts a circular dust removal method with upper air intake and side suction air. The clean air enters the sandblasting room from the top of the room body, and the dust removal fan sucks the polluted air in the room into the dust collector through each dust suction port for collection and processing.

Since the dust recovery suction inlets of the environmentally friendly pneumatic recovery sandblasting room are all arranged under the room body and on the sidewalls, the airflow drives the dust to always move from top to bottom, and the dust is always suppressed in the lower part of the sandblasting room.

The dust concentration in the space above 0.5 meters in the sandblasting room is very low, which provides high visibility and a good working environment.

How to design sandblasting room?

As an investment product, how to design a suitable sandblasting room is a question worthy of attention. A suitable sandblasting room can not only help you save costs, but also create profits for you and help your business to a higher level.

Choosing a sandblasting room is a relatively open question, but in general, these criterions should always be followed:

1 The size of sandblasting room

You need an encloser place to put the sandblasting room. The size of the space depends on the size of object item that need to sandblasting. And when designing the size of the room, in addition to the size of the workpiece, you also need to consider the area required by the workers for sandblasting activities, the best blasting distance between the spray gun and the workpiece, etc. Generally, adding a distance of 1m around the workpiece is sufficient.

2 Material Handling system

The conveying method of the workpiece is also the focus of attention when designing the blasting room. How to put the items you need to blast into the blasting room, and handle them safely and conveniently, and then move the items out for storage, or proceed to the next process?

Most users will choose a trolley with rails for material handling and movement. This is the most economical and safe method. During sandblasting, the trolley is parked in the sandblasting room and the workpiece can be easily sandblasting.

If you are handling very large and heavy pieces of equipment like a pump station or engine block, with low volume, using a forklift could be the right solution for you.

Another method is to install an overhead conveyor on the roof of the blasting room, which allows the items to hang below them and moved in and out the blasting room.

Some users will choose the crane they already own, and design a movable roof controlled by cylinder, can let the crane into the blasting area with workpieces when the movable roof is opened.

3 Floor recovery system

Floor Recovery System is an efficient and inexpensive solution for recovering used abrasive with minimal effort from operator. System is suitable for large or small rooms, and offers flexibility in recovery floor layouts. Abrasive residues must be swept or shoveled into floor hopper to be recovered by system.

This recovery system can handle major light-to-heavy abrasives available on the market today, including heavy media such as aluminum oxide, steel shot, and steel grit. With media recovery capacity of over 2,000 lb. per hour and various floor hopper layouts, this system is designed for maximizing operator productivity while simplifying room cleaning after blasting operations.

4 Sandblasting Room Ventilation

During the sandblasting process, a large amount of dust will be generated, which will make the inside of room dusty. And the chemical nature of the dust will endanger health. Designing a suitable dust collector is needed.

There are three different airflow options to achieve this:

  1. Down-draft
  2. End-to-center
  3. Cross-draft

The working principle of the dust removal system in the room is: because the dust extraction fan extracts the gas and dust in the sandblasting room, the airflow outside the sandblasting room enters the sandblasting room through the coarse filter on the top of the sandblasting room, and then passes through the top of the sandblasting room. The uniform flow plate enters the sandblasting studio in the sandblasting room, forming a top-down airflow on the cross section of the sandblasting room, and the dust and dirt in the sandblasting room enter the dust extraction port with the airflow, and finally pass through the dust removal The pipeline enters the dust removal system, and the clean air is filtered by the dust removal system and discharged into the atmosphere. The dust and dirt are stored in the dust cylinder for regular cleaning.

How to calculate the air volume of dust collector in the sandblasting room?

Calculated by cross-sectional area. The method of calculating the cross-sectional area is to multiply the length by the width. It is important to explain here that the length and width are the areas that the ventilation can pass through. If there are other flowing air inlets besides the door, it should be added for rational calculation. :Air volume=cross-sectional area*wind speed*3600

5 ROI

It’s also important to consider the return on investment (ROI) when building a blast room facility. The amount of blasting done over a given period and the number of employees required both will influence blast room decision-making. Additionally, selecting the proper abrasive requires a thorough consideration of all of the parts that will be blasted. For example, mineral abrasives break down faster than steel grit abrasives but allow for greater flexibility for various blasting needs. Disposal costs also need to be factored in and can vary greatly depending on material and volume.

The operation process of sandblasting room

The most widely used sandblasting room in the field of rust removal of workpieces is the automatic sandblasting room, which is applied to various industries and has the advantages of convenient operation and high production efficiency. The operation process of the automatic sandblasting room equipment is as follows.

  1. The gas storage tanks, pressure gauges, and valves of the automatic sandblasting room should be checked regularly. The gas storage tank discharges dust once every two weeks, and the filter in the sand tank is checked once a month.
  2. Check whether the ventilation pipe of the sandblasting equipment and the door of the automatic sandblasting equipment are sealed. Five minutes before work, the ventilation and dust removal equipment must be activated. When the ventilation and dust removal equipment fails, the equipment is prohibited from working.
  3. Wear protective equipment before work. It is not allowed to operate automatic sandblasting equipment with bare arms.
  4. The compressed air valve of automatic sandblasting equipment should be opened slowly, and the air pressure must not exceed 0.8MPa.
  5. It is not allowed to blow dust on the body with compressed air in the automatic sandblasting room.
  6. When the sandblasting equipment is working, no unrelated persons are allowed to approach. When cleaning and adjusting the operating parts, the machine should be shut down.
  7. The sandblasting equipment’s operating procedures The sand size should be compatible with the work requirements, generally between ten and twenty, and the sand should be kept dry.
  8. After the work is finished, the ventilation and dust removal equipment of the automatic sandblasting machine should continue to operate for five minutes and then shut down to discharge indoor dust and keep the site clean.

Sandblasting pipeline, gas path

Check whether the sandblasting hose is damaged and replace it immediately. Check whether the connection is firm, and if there is leakage, eliminate it immediately.

Check the damage, wear and connection of the air pipe to ensure that each joint is sealed reliably. If it is worn, it should be replaced immediately.

Floor recovery system

At work and after get off work every day, check whether there are large impurities in the  floor recovery system, if so, it should be removed.

Artificial respirator

Before going to get off work, check whether the protective glass of the respirator is damaged or whether it affects the processing operation. If it is affected, replace it immediately. Ensure personal safety; check the air filter and air source of the respirator to ensure normal air supply.

Because the glass of the protective clothing is fragile, it should be handled with care during sandblasting. Don’t touch it indiscriminately, and it should be kept stable when not in use.

Blasting gun, nozzle

Check the wear of the gun and nozzle, if it is severely worn or the efficiency of the sandblasting process is significantly reduced, replace it immediately.

Environmental protection sandblasting room Because the nozzle, protective clothing glass, spray gun switch and other parts are fragile, you should hold it gently during sandblasting, do not shake or touch, and keep it steady when not in use.

Sand control valve sand discharge adjustment lever

Check whether the adjusting rod is worn out and must be replaced in advance.

Protective rubber in the room

Check whether the rubber in the room is damaged and whether it is replaced according to the situation.

Door, safety power switch, gun switch

Check whether the gate control safety switch and spray gun switch are sensitive and effective. If the action fails, it should be repaired immediately.

Seal

Check the seals, especially the door seals. If they are found to be invalid, they should be replaced immediately.

Electrical control

Check whether the operation control buttons of each device are normal. If an abnormality is found, it should be repaired immediately.

Lighting

Check the protective glass, ballast and bulb usage of the lamp.

Filter dust box ash box

Clean the dust in the dust box of the filter element and the dust box of the separator before work.

According to the above-detailed understanding of the maintenance and maintenance methods of the environmental protection sandblasting room, the equipment can be used better, the failure of the equipment can be reduced, and the service life of the equipment can be prolonged on the premise of ensuring the efficiency of the equipment.

Sandblasting suit

Whenever workers are sandblasting, the steel sand will hit the surface of the workpiece, and at the same time, the steel sand will splash around, the splashing steel sand will hurt the workers, and the workpiece will produce a lot of dust after descaling, the dust will cause harm to the human respiratory system, so the workers must wear protective clothing and sandblasting helmets whenever they work. Sandblasting suits are used to protect workers. They consist of sandblasting helmets, sandblasting suits, gloves, and breathing filters, with which workers can work safely when they wear them.

Abrasive

Abrasive blasting is the process of cleaning the surface of rough chemical parts by using the impact of steel sand at high speed. Abrasive blasting with sands containing crystalline silica can cause serious or fatal respiratory disease. We use steel grit instead of abrasives containing Silicon dioxide to protecting workers. There are many different types of steel shot, including steel grit, steel shot, cut shot, abrasive shot and stainless steel shot, and the type of shot to be used when blasting is adjusted to suit different needs.

Requirements and preparation of sandblasting room

The sandblasting system relies on a modern, well-designed sandblasting chamber to ensure a closed, controlled, and clean environment for abrasive recovery. Whether it is to remove an existing coating or to prepare a surface for a new coating, it is essential to use an air compressor for optimal surface treatment.

Sandblasting rooms also have many sizes and material preparation requirements. Some factors to consider include the size and weight of the maximum workpiece, material handling method, sandblasting time, and base material. Also, the width and length of the room had to be increased by four to five feet, depending on the size of the largest piece. The height of the room is also determined by the largest workpiece, but material handling plays an important role in this.

Sandblasting room shipped to Australia 2

Components and design of the sandblasting room

The dust collection system is the key component of the sandblasting room. Reverse pulse cartridge precipitators are now standard because they have a reliable exhaust motor that takes the air out of space and traps it in the filter. These collectors also feature enhanced pleated paper to improve filtration efficiency and reduce size requirements for the facility’s dust collection system. Proper maintenance, such as occasional dusting of ink cartridges, is also important. However, some modern techniques allow self-cleaning through a brief reverse flow of air. Pulse sensing technology differentiates the pressure between the clean and dirty sides of the filter. The dust collector must produce 50 feet of air per minute through the enclosure. The production of dust or hazardous materials may even require rates of up to 100 FPM.

Whether you need to remove abrasive material from the inside of the tank car or from smaller gaps or containers, your plan should include vacuum recovery. Blasting medium recovery systems should be carefully analyzed, as an efficient recovery system is essential to minimize cleanup time and overall project costs. Efficient capture of the media for delivery to the recovery point and reliable transport of the media to cleaner areas are essential for normal performance.

Manufacturers and distributors of these systems typically offer a variety of recovery solutions for all or part of the floor space installation. With no moving parts, pneumatic recovery systems work well with lightweight media such as agriculture, plastics, glass beads, and alumina. Mechanical flooring reduces procurement and installation costs and utilizes pneumatic power. It also has trapezoidal steel blades to provide power.

The spiral bottom plate is generally used for steel sand and steel shot. Although they are more expensive and require more digging, they are best at moving the heaviest abrasives.

The cleaning system requires regular shut down for cleaning, which is very suitable for infrequent or irregular blasting needs. These floors use swing technology to move abrasive and dust to cross plates or screw conveyors.

The application of sandblasting room

The sandblasting room is a kind of machine that can spray various abrasives (silica sand, iron sand, steel shot, etc.) on the surface of the workpiece with air pressure. The abrasive sprayed on the surface of the workpiece is impacted on the metal surface to remove surface impurities, rust, paint, oxide scale, etc. According to the spraying method, it is divided into self-priming type and press-in type. Because the press-in type is to mix and spray compressed air and abrasive in the same container, the compressed air is fully utilized, and the air flow and sand volume are easy to adjust. It is suitable for large-area cleaning with high efficiency and is also widely used in pipes. Clean the inner wall.

What is sandblasting: a method of cleaning the surface with high-speed moving gravel. Can remove the surface oxide scale, grease, paint, etc., to obtain a more uniform surface quality. The subsequent process can be welding, oxidation, coating, surface chemical heat treatment, phosphating, etc. Sandblasting can generate residual compressive stress on the surface of the workpiece and make the surface quality of the workpiece uniform, which can improve the fatigue strength of the workpiece. The strengthening effect is worse than that of shot blasting, and the deformation of the workpiece is smaller than that of shot blasting.

The application of sandblasting room 1

Application range of sandblasting room:

  1. Pretreatment: Electroplating, painting, spraying, etc. are all covered by sandblasting before processing, the surface is cleaned, and the adhesion and corrosion resistance of the covering layer are greatly improved.
  2. Cleaning: Casting parts, stamping parts, welding parts, heat treatment parts and other metal workpieces to remove oxide scale, residue, dirt; surface cleaning of non-metallic products, removing black spots on the surface of ceramic blanks and reducing paint patterns, etc.
  3. Refurbishment of old parts: refurbishment and cleaning of all moving parts such as automobiles, motorcycles, and electromechanical equipment. At the same time, fatigue stress is eliminated and service life is prolonged.
  4. Light decoration: all metal products and non-metal products (plastic, crystal, glass, etc.) surface traces are eliminated, and the argon light matte surface treatment improves the quality of the product surface.
  5. Mold processing: argon matte surface treatment of the mold surface, graphic production, and mold cleaning, so as not to damage the mold surface and ensure the accuracy of the mold.
  6. Burr treatment: Removal of tiny burrs on machined parts, and burrs on injection molded parts.
  7. Rework of defective products: Removal of defective covering layer of products, removal of defective surface coloration and printing.
  8. Strengthening: Increase the surface hardness of metal parts and eliminate stress, such as surface treatment of aircraft blades, springs, machining tools and weapons.
  9. Etching anti-skid processing: metal products, non-metal products surface etching patterns, text and anti-skid treatment, such as: marble, anti-skid handles, seals, stone inscriptions, etc.

How many type recovery system of the sandblasting room?

Single screw recovery system

Single screw recovery system is the most economical design. The main components of the system including screw, bucket elevator, separator, ladder and storage hopper. This type is the basic recovery system of sandblasting room, which can be extended to L type, H type, U type or fully automatic recovery system. It is most suitable for low or medium production.

L type recovery system

L type recovery system is add one longitudinal conveyor in one side of the blast room allows the abrasive delivery from the blasting nozzle, which is blown or bounded off the workpiece, to strike the side walls and fall into the conveyors and automatically reclaim approximately 40-70 percent of the blast media. After sandblasting , push the abrasive on the sandblasting room floor into the screw or scraper conveyor. This is best suited for low to medium production.

H type recovery system

H type recovery system  adds two longitudinal conveyors on each side wall of the sandblast room allows the abrasive delivery from the blasting nozzle, which is to blow or bounce workpiece, to strike the side wall and fall into the conveyors and automatically reclaiming approximately 60-90 percent of the abrasive. After sandblasting , push the abrasive on the sandblasting room floor into the screw or scraper conveyor. This is best suited for medium to high production.

U type recovery system

U type recovery system adds two longitudinal screw or scraper conveyors on each wall of the blast room and positions the cross screw or scraper conveyors along the back wall of the blast room. This allows the abrasive delivery from blasting nozzle, which is blow or bounce off the workpiece, to strike the side wall and back wall of the blast room and fall into the reclaim system. The U type floor design will automatically reclaim 60-90 percent of the abrasive. After sandblasting , push the abrasive on the sandblasting room floor into the screw or scraper conveyor. This is best suited for medium to high production

Full floor automatic recovery system

Full floor automatic recovery sysytem use multiple screw components or scraper components to create a fully automatic, high-capacity abrasive reclaim system where 100% of the abrasive are returned to the separator system during the blasting operation. This allows for a faster reclaim and full recovery of the abrasive, saving both of your time and money in your blasting operation. The Full Floor Reclaim System allows the maximum efficiency of your abrasive blasting system. This abrasive blasting reclaim system is veryl suitable for high production requirements.

How does sandblasting room complete the rust removal

How does sandblasting room complete the rust removal

The main feature of the sandblasting room is that the operator is indoors during the blasting process. The protective clothing and helmet can prevent the operator from being impacted by abrasives, and the ventilation device provides fresh air to the operator through the helmet.

The blasting room is mainly used for large parts or using automatic blasting equipment to process very expensive parts. The nozzle manipulator installed in the sandblasting room can automatically sandblast the surface of the parts, and the hard-to-reach areas of automatic sandblasting can be completed by manual sandblasting. This not only maintains flexibility, but also reduces the requirements for the number of sandblasting operators.

The abrasive transportation method is another highlight of the equipment design. In addition to the well-known flat conveyor floor that requires a small installation depth, QGMA has extremely rich experience in screw conveyors and automatic scraper abrasive conveying technology.

How does sandblasting room complete the rust removal 1

The process of QGMA sandblasting room processing products is very simple. It is to build a room with rubber fixed inside. The shot material below can be recycled. There is a sandblasting machine outside. The internal operator uses the sandblasting machine to hit the sand at high speed on the workpiece. The surface, forming a certain degree of roughness, thereby improving coating adhesion and extending the service life of the workpiece! The sandblasting process is roughly divided into 5 steps to control: pre-control, abrasive control, tool control, condition control and quality control. Let me talk about the details of various controls.

  • Early control

Before sandblasting, check the surface of the workpiece carefully, remove welding slag, splashes and other attachments, and clean the surface grease and soluble dirt. Sandblasting can only be carried out under the premise of cleaning the surface of the workpiece.

  • Tool control

When the sandblasting machine is in operation, the air pressure of the air compressor is 6.0×105~6.5×105Pa, and the air pressure range is 0.5×105~1.0×105Pa. Generally, the air pressure of the sand bucket is 4.5×105~5.5×105Pa, not less than 4.0×105Pa. Before sandblasting, check whether the pressure vessel manufacturer holds the production license issued by the relevant department, whether the protective tools worn by the sandblaster, the safety belt (rope) and the oxygen supply device are safe and reliable, and whether the nozzle is worn out. The nozzle should be replaced when the diameter is increased by 25%.

  • Condition control

The compressed air used in the sandblasting room must be treated by a cooling device and an oil-water separator to ensure dryness and oil-free; the oil-water separator must be cleaned regularly. The distance between the nozzle and the surface of the base steel should be 100-300mm, and the non-sand-blasting parts should be shielded and protected before sand-blasting. The angle between the spray direction and the surface normal of the base steel is preferably 15°-30°.

After sandblasting and rust removal, before proceeding to the next process, in case of rain or other conditions that cause the surface of the base steel to be wet, after the environment has reached the construction conditions, use dry compressed air to dry the surface moisture before the construction, if necessary Sandblasting, do not reduce the abrasive requirements, so as not to reduce the roughness.

When the blasting room is working, the nozzle of the blasting machine should not stay somewhere for a long time. Sporadic operations should be avoided in the blasting operation, but the spray area should not be too large at one time. The time between the painting or thermal spraying process and the surface pretreatment process should be considered Interval requirements. Use manual or power tools to remove rust on the parts that cannot be sprayed by the spray gun.

  • Abrasive control

The sand used for rust removal in the sandblasting room must be hard, angular, dry, free of dirt and other impurities; quartz sand is better, coarse river sand is also acceptable; at the same time, the sand transportation conditions, unit price, and recovery capacity should be considered Factors such as: sand size is 0.5~1.5mm, it must be dried before screening, stored in a shed, indoors, sieve size: coarse sieve 40~48 holes/cm2 (particle size 1.2 mm), fine sieve 372~476 holes/cm2 (particle size 0.3mm).

After the rust removal plan is determined, the abrasive can be river sand, quartz sand or a mixture of the two. In the consolidation of Gangnan Reservoir, after pre-spraying comparison, the rust removal effect of mixing quartz sand and river sand at a ratio of 1:1 is the best.

  • Quality Control

After the sandblasting room is completed, the sandblasting and rust removal parts should be thoroughly inspected first, and then the cleanliness and roughness of the surface of the base steel should be inspected. The focus should be on the parts that are not easy to spray, and the requirements for rust removal by hand or power tools can be appropriately reduced. When inspecting the cleanliness and roughness of the surface of the base steel, firstly, it is strictly forbidden to touch with hands; secondly, it should be carried out under good scattered sunlight or artificial lighting conditions with equivalent illuminance to avoid missed inspection.

Sandblasting room composition

The scraper-type sandblasting room is a large-scale sandblasting room. The sandblasting (shot) room is composed of six major systems: workpiece handling system, sandblasting (shot) system, abrasive recycling system, abrasive sorting and recycling system, dust removal system and lighting system.

Scraper conveying projectiles has the advantages of high efficiency, energy saving, and low failure rate. The key is that compared with large bin-type screw mechanical recycling, it can greatly reduce the height of the foundation and reduce the cost of civil construction.

Scraper type sandblasting room working principle

The abrasive is ejected from the blast gun and falls on the load-bearing grating floor of the blasting room. The longitudinal pulsating scraper pushes the abrasive, debris and dust into the screw conveyor, and the screw conveyor transports them to the bucket elevator After passing through the separator, the good abrasive re-enters the sandblasting machine, while the dust and debris will automatically fall into the dust collecting cylinder.

The scraper blasting room system can run any kind of abrasive (swinging bed shot blasting machine, inclined drum shot blasting machine).

Features of sandblasting room:

  • The scraper-type sandblasting room can run any kind of abrasive and has a wide range of applications.
  • The scraper blasting room consumes low power and saves energy.
