    Ball Mill: Operating principles, components, Uses

    Several types of ball mill exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 litres for planetary ball mill, mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills.

    Choosing a SAG Mill to Achieve Design Performance

    designing the new SAG mill chamber for optimum conditions at the design point is clearly established. For the operating load range just beyond the optimum performance conditions, a linear model was developed to assess the lost production that would result from running the mill at too high a load level.
