According to this definition given that the energy utilization in a ball mill is between 1×10 −3 and 4×10 −3 m 2 J and that the crack resistance value is between 30 and 60 Jm 2 the theoretical efficiency of the ball mill should be in the range of 15–12More Details
May 01 1984 · Ball mills 55 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 factorMore Details
