Ball Size Calculation For Ball Mill

Ball Size as Initial Charge. Commercial ball sizes 10 150 mm Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed i.e. d V 0.40 .
