During the cleaning process of the descaling machine, the electric-controlled adjustable-speed conveying roller conveys the round steel into the projectile area in the cleaning machine room, and all surfaces of the round body are hit and rubbed by strong and dense projectiles from different coordinate directions, so that the The oxide scale, rust layer and its dirt will fall off quickly, and the surface of the round steel will get a smooth surface with a certain roughness.

The projectiles and rust dust falling on the steel are blown by the purging device, and the dust mixture that has fallen is conveyed to the chamber body hopper by the recovery screw, and the vertical and horizontal screw conveyors are collected in the lower part of the elevator, and then lifted to the upper part of the machine for separation. In the separator, the separated pure projectiles fall into the separator hopper for shot blasting recycling. Dust is generated during shot blasting, which is sent to the dust removal system by the exhaust pipe. The purified air is discharged into the atmosphere, and the granular dust is captured and collected. There are 1 and 3 common continuous straight-through round steel shot blasting machines. , l5, 25, up to 100. In order to ensure the effect of removing iron sheets, 3 to 8 projectiles are generally configured.
