Ball mill is the key equipment for crushing materials after crushing. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics.
The ceramic ball mill is a ball mill made of ceramic. Small capacity is generally suitable for intermittent small batch production of product trial production. It is another new type of energy-saving ball mill equipment for mineral processing machinery.
The classifier is widely used in the beneficiation plant and the ball mill to form a closed loop process to split the ore
