  • MODULE 5 FUNCTIONAL PERFOMANCE OF BALL MILLING

    For example, when 60% of the solids in a ball mill is coarse, then the coarse solids inventory * in the mill is 60%, and only 60% of the mill grinding volume and power is used for the grinding of coarse particles. The classification system efficiency of the circuit is then only 60%.

  • Factors Affecting Ball Mill Grinding Efficiency

    a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the
