    Abstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding media with different shapes.

    Jul 01 2003 Figure 3 depicts the effects of media size on grinding times. From this plot it is shown that a target fineness of 80 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes the target grind is achieved in only 150 minutes.

    Theory and Practice for U S Stoneware

    When too slow speeds slipping of the media occurs. Here the grinding media acts as a static unit in relation to the walls of the rotating mill. This leads to grooving of the mill walls and flattening of the media. The same action can result in mills operating at optimum speed if low media charge or low consistency is used in the mill.

    The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media usually 12 mm or larger and run at low rotational speeds of 10–50 rpm. Power input to attrition mills is used to agitate the medium not to rotate or vibrate heavy drums.
