Roller Conveyor Shot Blasting Machine is heavy duty blast cleaning equipment. Roller conveyors are made of three parts, feeding rollers, middle rollers and out-feeding rollers. Feeding rollers deliver work pieces to middle rollers in blasting chamber where work pieces will be blasted by blasting wheels mounted on the blasting chamber walls. Out-feeding rollers deliver blasted and finished work pieces out of blasting chamber for unloading.
Feeding rollers and out-feeding rollers are driven by variable speed reducers. Roller speed can be adjustable according to work pieces surface condition and metal surface finish level.





Roller Conveyor Shot Blasting Machine is heavy duty and versatile wheel blast cleaning equipment.
Work pieces include H beans, I beams, steel plate, sheets and strips, square tubes, tubes and pipes, bars and rebars. Fabricated steel works and structural steel works can be blasted thoroughly to reach SA 2.5 or even SA 3.0 ready for priming and coating.
