19/6/2015· The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
Modelling mineral size reduction in the closed-circuit ball mill at the Pine Point Mines concentrator. International Journal of Mineral Processing 1981,8 (1),61-78.
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., dâ†“V = 0.40 KâˆšF dB = ball size (cm) F = feed size (cm) K = proportionality constant described as the grindability factor
