What is the difference between ball mill, autogenous mill and semi-autogenous mill?
Ball mill: uses the collision and friction between balls to grind non-ferrous metals such as ores and sand. The material enters the drum through the feeding device, and the grinding medium also enters at the same time. After the drum starts to rotate, the material and grinding media continue to collide and rub in the drum, so that the material is gradually ground into fine powder.
