When the main shaft rotates, the grinding medium is driven by the rotating disc to grind the slurry pressed into the cylinder, so that the solid material therein is refined and qualified slurry flows out through the filter gap or sieve hole smaller than the particle size of the grinding medium. Since the sand mill needs to use grinding media, the medium contains suspended particles or crystals, which accumulate for a long time and clog between the moving ring and the shaft, between the springs, between the spring and the spring seat, etc., so that the compensating sealing ring cannot float and loses the compensating buffering effect, so leakage problems will occur and the casing will be polluted. In addition, due to the infiltration blockage, the grinding cylinder needs to be frequently maintained, so the grinding cylinder needs to be frequently disassembled and assembled, and the grinding cylinder is heavy and it is not convenient to move it up and down frequently. Therefore, the present application provides a sand mill casing to address the above problems.
