News Introduction:The Ball Mill was originally designed for 7,000 kW power draw, a with a maximum ball charge of 31% (65mm diameter ball size) to perform size reduction from 2a mm -10 mm feed size range to 180a microns - 250 microns product size range. The mills are equipped with trommel screens having an aperture of 12.7mm x 31.8 mm.
