The steel plate shot blasting machine is mainly composed of preheating, shot blasting, painting and drying processes. It is applicable to the surface derusting and painting process of steel plates, profiles and structural parts in ships, automobiles, locomotives, bridges, machinery and other industries. During the cleaning process of the shot blasting machine, the steel structural parts or steel are sent into the blasting area of the cleaning machine room by the electrically controlled adjustable conveying roller table. All sides of the steel body are hit and abraded by strong and dense projectiles from different coordinate directions, so that the oxide skin, rust layer and dirt on it fall off quickly. The steel surface will obtain a smooth surface with a certain roughness, and the workpiece will be loaded and unloaded at the inlet and outlet roller tables on both sides of the cleaning room.

The shot and rust dust falling on the steel are purged by the purging device, and the shot dust mixture falling down is conveyed to the chamber funnel by the recovery screw. The vertical and horizontal screw conveyor is collected at the lower part of the elevator and then lifted to the separator at the upper part of the machine. The separated pure shot falls into the separator hopper for shot blasting recycling. The dust generated in the shot blasting of the through-type shot blasting machine is sent to the dust removal system by the exhaust pipe, and the purified gas is discharged into the atmosphere. The granular dust is captured and collected. The through-type shot blasting machine is mainly used for the stress relief and surface rust removal of large I-shaped steel and other high steel structural parts used in construction, bridge and other industries.
