The self-grinding sand making machine is a new type of mill independently developed and researched by our company. It is particularly suitable for the preparation process of quartz sand, allowing raw ore to be directly fed into the mill to produce coarse powder products.
The main working component is a horizontally placed rotating drum supported by large sliding bearings or rolling bearings at both ends. The dry method is used to avoid water contamination. To prevent wear on the drum and iron contamination of the material, the inner wall of the drum and the end covers on both sides are lined with silica or alumina linings. When the autogenous mill rotates, material is simultaneously fed through the feed inlet.,Through the relative motion between materials, mutual impact, and collisions between materials and the cylinder lining, the purpose of crushing and grinding is achieved. Qualified materials flow out of the cylinder through the discharge grate screen, while unqualified materials continue to be ground inside the cylinder, thereby realizing the organic integration of impact, crushing, and grinding.
