steel plate shot blasting machine 1

Steel plate/ steel sheet shot blasting machines are specially designed for surface treatment to steel plates.

Steel plate shot blasting machines by QGMA adopt roller conveyor system to transport work-pieces through blasting chamber. The transport speed is adjustable by converter according to different work-pieces.

To achieve higher surface cleanness after blasting process for the next painting process, QGMA offers extra surface cleaning designs like scraper, roller brush or blower.

Steel Plate Shot Blasting Machine Applications

  • Cleaning plate
  • Corrosion removal
  • Remove welding slag
  • Remove rust
  • Paint Stripping
  • Provides ideal surface finish (SA2.5-3.0) for securing a continuous and effective bond between the steel surface and coat.

Key feature of steel plate shot blasting machine

Blast wheel

☆Dynamic Simulation Designblast wheel 2
The liners form a round track for abrasive, which allows all abrasive leave the turbine when they reach the highest speed with the least internal bounce and self-wear. Can offer high blast speed and full abrasive cover.
The maximum thickness of blast wheel shell can reach 70mm, better sealing effect, long service time.
The interior of the blasting wheel is turbo type, abrasive will not not stay in the distributor. Abrasive utilization rate increased to 99%, improve efficiency by 30%.
Blast wheel bottom has cushioning rubber, which can reduce vibration.
☆Blade & Impeller
The material of impeller is 40CrMnMo, the material of blade is high chorme wear-resistant casting iron, the hradness can reach HRC60-65.

Abrasive cleaning up system

abrasive cleaning up system 1

☆Including: brush, screw conveyor, abrasive blowing fan and lifting mechanism.
☆The material of brush is high strength MC nylon, it can use about 5 years.
☆The nozzles are adjustable in height and therefore adaptable for the treatment of different height steel plate.
☆After abrasive cleaning up system working, the surface of steel plate no any steel shot and dust

Blasting room

☆ Working principleBlasting chamber
The engineering team uses 3-D dynamic simulation design blast turbines layout to ensure that the steel shot ray can cover the surface of the workpiece 360 degrees.
☆10 Years Warranty
Shot blasting chamber with Mn13 steel guard plate which has high impact toughness and high service life, fully realize the reflection funcation of abrasive and improve the cleaning quality.
That we promise 10 years maintenance-free warranty to blasting chamber.
☆High sealing performance
3+ layers of sealing curtain in inlet, outlet opening and between chambers. The curtain layers are natural rubber material with leaf spring which can automaticlly reset,
that prevent the abrasive spatter out duing the blasting and ensure the safe.

Dust collector

dust collector 232Max 3-grade dust collecting design can achieve max 99% clean efficiency.

☆Level-1 Dust Collecting: a gravity settling box above inlet/outlet chamber will make the abrasive shot in airflow drop back to chamber, so the dust collecting filter will not be damaged by abrasive shot, can a chieve a longer service time.
☆Level-2 Dust Collecting: Cyclone dust collector have 2 collection poits for dust and debris, primary collection point is for heavier chips and debris, while the second point is for finer particulate matter. Cyclone dust collector use a centrifual force for separation. Then airflow transition into downward spiral and forces the bigger contaminants into first collecting point, then the smaller contaminants into the second point.
☆Level-3 Dust Collecting: high filtering areage cartridge type or venturi design bag type filter can offer a long service time high filterability effect, the final cleaning efficiency is upto 99%.
