The mesh belt pass-through shot blasting machine uses a conveying mesh belt as the carrier of the workpiece. One end of the shot blasting chamber is the loading station, and the other end is the unloading station. When working, the parts are placed on the conveyor belt at the loading station, and the conveyor belt slowly enters the shot blasting chamber for shot blasting, and then the workpiece is removed at the unloading station. The mesh belt shot blasting machine has the characteristics of good continuity, no collision, high cleaning efficiency, large production batch, no pit, etc. It is mainly used for surface blasting of thin-walled castings, fragile iron or aluminum alloy castings, ceramics and other small parts. Shot cleaning can also be used for shot blasting of mechanical parts.
