This machine is a high-performance shot blasting cleaning equipment with roller conveyor continuous feeding. During the cleaning process, the electrically controlled variable speed conveyor roller conveyor sends steel structural components or steel into the blasting area inside the cleaning machine room. When the surrounding surfaces are hit and rubbed by strong and dense bullets from different coordinate directions, the oxide skin, rust layer, and dirt on them quickly fall off, and the steel surface obtains a smooth and smooth surface with a certain roughness. The workpiece is loaded and unloaded on the inlet and outlet roller conveyor on both sides of the cleaning room. The pellets and rust dust that fall on the steel are blown by the blowing device. The mixture of pellets and dust is transported by the recovery screw to the chamber funnel, and the longitudinal and transverse screw conveyor is collected at the lower part of the elevator. It is then lifted into the separator at the upper part of the machine. The separated pure pellets fall into the separator hopper for recycling. Dust is generated during shot blasting, which is sent to the dust removal system through the exhaust duct. The purified gas is discharged into the atmosphere, and granular dust is captured and collected.
