Exploring ball size distribution in coal grinding mills

Exploring Ball Size Distribution In Coal Grinding Mills

Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill. The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the ...
