Steel structure shot blasting machine

Author: admin Source: This station Time: 2015-12-30 11:05

In the cleaning process of steel structure shot blasting machine, the steel structure parts or steel products are sent into the shooting area in the cleaning machine room by the adjustable speed conveying roller table controlled by electricity. All sides of the blast machine are hit and rubbed by strong and dense projectiles from different coordinate directions, so that the oxide scale, rust layer and dirt on the steel surface will fall off quickly, and the steel surface will obtain a smooth surface with a certain roughness Both sides of the import and export roller table loading and unloading workpiece. The shot and rust dust falling on the steel are swept by the blowing device, and the shot dust mixture is transported to the chamber hopper by the recycling screw. The longitudinal and horizontal screw conveyor is collected at the lower part of the elevator, and then lifted to the separator on the upper part of the machine. The separated pure shot falls into the separator hopper for shot blasting recycling. The dust generated in shot blasting cleaning is sent to the dust removal system by the exhaust pipe, and the purified gas is discharged into the atmosphere, and the granular dust is captured and collected.
