Ball mill Wikipedia
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing The ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former energy calculation model of ball kinematics based on ball mill coal ,ics based on coal load of ball mill is proposed in this paper. Material levels are detected by the transformation rule of power and coal load in power. 1715
