A casting equipment that uses high-speed pellets thrown by a shot blasting machine to clean or strengthen the surface of castings. The catenary shot blasting machine can simultaneously perform sand falling, core removal, and cleaning on castings.
The pellet circulation system in a shot blasting machine is composed of several parts, including a feed screw, elevator, separator, pellet control system, and hopper.
When encountering poor pellet circulation in a shot blasting machine, common issues may include loose elevator belts, slipping elevator belts, or leaks in the pellet storage bin, which reduce the amount of circulating pellets.
This can also be caused by wear of the pellet recovery scraper, blockage of the pellet conveying pipe due to pellet agglomeration, excessive impurities in the drum screen blocking the screen holes and affecting pellet screening, or jamming of the screw conveyor. When using a catenary shot blasting machine, it is necessary to carefully inspect each component.
