  • Grinding Media Size Distribution In Ball Mill

    Grinding media size distribution in ball mill. Grinding media size distribution in ball mill grinding media size distribution in ball mill the optimal ball diameter in a mill grinding quartz and copper ore in a laboratory ball mill, there has been defined a general form the topic of.Grinding media is grinding feed High capacity (short retention time) Sensitive to feed composition (critical size material) Semi-Autogenous Grinding (SAG) Mill. Wet or dry Higher capacity than A-G mill grinding Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12 ball charge (ball dia.100- 125 mm).Jan 01, 2012 The successful use of the simulator to predict the effect of ball make-up on the grinding product size distribution in one plant is also reported.INTRODUCTION Adjusting the characteristics of the grinding media charge in grinding mills holds significant potential for optimisation of mill.Ball Size Distribution. As the mill starts, grinding action and throughput increases. However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Under this conditions, the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed.
