That can remove steel surface rust and eliminate surface stress, improve the adhesion between the paint film and the steel, improve the inherent quality of the steel, and extend its service life.

Key feature of roller conveyor shot blasting machine

Blast turbine

☆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.
☆Motor: Siemens


Roller Conveyor System

roller conveyor system of shot blasting machine☆ Infinitely variable speeds
The conveying system of the whole production line adopts stepless variable speed adjustment, and the conveying system is composed of the input roller conveyor, blasting chamber roller conveyor and the output roller conveyor.
☆ Proper alignment
High quality carbon seamless steel pipe is adopted for the roller shaft of the input and output roller conveyor, and roller is first welding and then processing, to ensure the concentricity of the roller. Usually it can use 8-10 years.
☆ Wear resistant sheath
The roller conveyor in blasting chamber has high chromium molybdenum wear resistant cast iron shealth, that can protect the roller conveyor avoid abrasive.


Blasting chamber

☆ 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.


Photoelectric sensor system

photoelectric detection

☆ 2 sets photoelectric sensor system are located at the inlet and outlet the chamber, grating density can be selected according to the size of the workpiece, used in pairs.

☆ The workpeice reach inlet of chamber, the photoelectric sensor system will send signal to computer then the machine will start to do the blasting work, and it will automatic stop after the workpiece out of the blasting zone. That will avoid the blast turbines work when the blasting chamber without workpiece, extend the service time of blasting chamber, and let energy cost saved max 30%.
