running a small ball charge in a ball mill

Indeed as explained previously at a mill stop the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle (βstatic= 143°). An online measurement of the similar angle (βdynamic) when the mill is running provides information about the dynamics of the charge.

Developments in iron ore comminution and classification

Jan 01, 2015 · Since the weight of pebbles per unit volume is 3555% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower. Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a
