Grinding device

Abstract

The utility model relates to the technical field of grinding, and discloses a grinding device which comprises a first circular plate, a supporting column, a second circular plate, a hollow shaft, a first grinding disc and a second grinding disc. In the using process, due to the fact that the second circular plate can slide relative to the multiple supporting columns, the bottom face of the first grinding disc can be attached to the top face of the second grinding disc under the action of gravity. After materials are added into the hollow shaft, the materials can fall into the first through hole. And then, under the driving of external force, the hollow shaft rotates relative to the second circular plate, so that the first millstone can be driven to rotate relative to the second millstone. In the process that the first millstone rotates relative to the second millstone, materials in the first through hole can be ground. And the ground materials can be discharged from the gap between the attaching surfaces of the first grinding disc and the second grinding disc, so that the grinding effect of the materials is ensured.
