efficency of ball mills

Ball mills 5 5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills particularly when the large mills carry 40% by volume ball charges This paper will explore factors used in scaling up ball mills showing where the advantages of one factor can possibly be negated by another factor The paper will propose possible operating Ball Mill 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

How to improve the grinding efficiency of the ball mill
