Roller conveyor shot blasting machine

Qinggong Roller conveyor shot blasting machine is used for de-scaling, de-rusting, paint removal, paint preparation and general cleaning of metal sheets, pipes/tubes, I-beams and weldments. Optimum blast results are achieved on thin gauge aluminum profiles as well as on heavy steel profiles and steel slabs. Standard roller conveyor machines can process parts from 600 up to 5,000 mm width with roller conveyor speeds from 0.5 to 4.0 m/min. High performance systems allow parts speeds of up to 7.5 m/min. The quantity of blast wheels and their position ensures optimum blast results. The thrown blast media is collected with screw conveyors and transported to the media hopper through an elevator, screen drum or tilting screen and air wash separator. The machine width, number of blast wheels and their location is determined by parts size and production speed. Standard systems are used for processing metal sheets and beams. Standard systems are frequently modified to allow processing of welding constructions of different sizes and geometries.
