Overflow ball mill is a kind of ball grinding mill which works in wet water state. It belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. Ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill.
key factors affecting mill throughput and grinding efficiency: mill speed, ball loading, and liner lifter face angle (angle between the lifter face in contact with a grinding ball and the lifter base). Its central hypothesis is that face angle drives a ball mill's grinding efficiency and throughput independently of the type of liner used.
