Ball Mill Designpower Calculation

Ball Mill Designpower Calculation

Jun 19, 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.May 30, the specific rates of breakage of particles in a tumbling ball mill are described by the equation si = axαi(q(z), where q(z) is the probability function which ranges from 1 to 0 as particle size.
