Description

[0002] Gypsum is a widely used industrial material and building material. It can be used as cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc. It needs to be ground during the production process. The existing waste gypsum recycling mill (Announcement No.: CN215234763U) has the following disadvantages in use:

[0003] During use, the gypsum to be processed is introduced into the grinding box through the side inlet and ground in the grinding box. However, during the feeding process, powder may diffuse into the air, resulting in a decrease in the surrounding air quality, affecting the health of the staff. In addition, during the grinding process, the gypsum is poured into the grinding box from one side, which may cause the gypsum to be on one side of the grinding box. During the grinding process, the grinding blades at other positions do not grind the gypsum well, thereby causing the service life of some grinding blades to be reduced. For this reason, this patent proposes a gypsum grinder to solve the above problems. Utility Model Content
