Working principle of roller shot blasting machine

The roller table pass-through shot blasting machine can work continuously and uninterruptedly, deoxidizing, cleaning and pretreatment of various steel materials, such as steel plates, steel materials, steel beams, section steels, steel pipes and steel castings, in a continuous way. The operation is simple, just load the steel material on the machine, press the start button, after a short cycle, the system will automatically unload the processed material, that is, the entire cleaning process is completed, and all dust and residual pellets are removed. material. During the cleaning process, the roller-pass type shot blasting machine is electrically controlled by the adjustable-speed conveying roller to send the steel structure or steel into the ejection area of the cleaning machine room, and its surrounding faces are hit by powerful and dense projectiles from different coordinate positions. With friction, the oxide scale, rust layer and dirt on it will quickly fall off, and the surface of the steel will obtain a smooth surface with a certain roughness. The workpiece is loaded and unloaded on the inlet and outlet roller table on both sides of the cleaning room. The projectiles and rust dust falling on the steel are blown by the purge device, and the scattered pellet dust mixture is conveyed to the chamber funnel by the recovery screw, and the vertical and horizontal screw conveyors are collected in the lower part of the hoist, and then lifted to the upper part of the machine. In the container, the separated pure projectiles fall into the separator hopper for blasting recycling. Dust generated in shot blasting is sent to the dust removal system by the exhaust pipe, and the clean air after purification is discharged into the atmosphere, and the particulate dust is captured and collected.
