Critical Speed Of Ball Mill

Processing ability: 0.5–500 t/h

Feeding size: ≤25 mm

Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
