Litchi Surface Processing Machine produces lychee surface stone by the high-pressure impact of steel grits on stone. The whole process starts with putting the stones on a conveyor belt manually or through automated equipment. The conveyor belt sends the stones to the blasting chamber. The centrifugal ejector projects the steel grits on the surface of the stone. Then, the finished products leave the conveyor belt to the area of the finished product. The steel grit can be reused after recycling, sorting, and other procedures.
