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 K√F

Abstract: We investigate the correlation between audio noise emissions from a laboratory-sized tumbling ball mill and its operating parameters, with focus on particle size and the type of ore inside the mill. We show that the average particle size is directly linked to the average energy in the signal. Where the mill is loaded with a mixture of ores, we demonstrate that a neural network can be ...
