This invention discloses an energy-saving grinding component for a sand mill, comprising an equipment housing containing a cooling tank, a grinding chamber located above the equipment housing, a spiral cooling cavity within the grinding chamber, a feeding pipe and a discharge pipe on the grinding chamber, and a cover fixedly mounted on the top of the equipment housing on one side of the grinding chamber. This invention improves the contact shearing efficiency between the grinding chamber and the material and grinding media beads through the coordinated operation of a cam, hollow shaft, grinding drum, and pin, achieving material grinding. Heat exchange is achieved between the cooling water in the spiral cooling cavity and the grinding chamber, enabling temperature control while recycling water resources. It also allows the warm water after heat exchange to quickly and thoroughly mix with the low-temperature cooling water and cooling elements, agitating the water to break up temperature stratification, ensuring the low-temperature stability of the return cooling water, and continuously guaranteeing the cooling effect. The entire process is driven by a single power source, balancing cooling efficiency and energy saving.

This utility model relates to a novel grinding disc-assisted grinding device for a sand mill, comprising a frame, a variable frequency motor fixedly installed inside the frame, a bearing seat fixedly installed above the frame, a drive shaft mounted on the bearing seat, the variable frequency motor and the drive shaft connected by a drive belt device, a grinding cylinder fixedly mounted on the bearing seat by grinding cylinder fixing bolts, and an end cap fixedly mounted on the other end of the grinding cylinder by end cap fixing bolts. The bearing seat, grinding cylinder and end cap form a sealed grinding chamber, in which a grinding disc, a conical spacer and a rotor are arranged. The conical spacer is a spacer with a tapered structure. The grinding disc and the conical spacer are mounted on the drive shaft, and the rotor is mounted at the farthest end of the drive shaft. The stirring device composed of the grinding disc, the conical spacer and the rotor rotates with the drive shaft. This utility model solves the problems of traditional cylindrical spacers not being able to fully utilize the grinding chamber space and having low grinding efficiency, and square spacers having high energy consumption and relatively insufficient uniform mixing ability.
