where d bmax is the maximum size of the feed (mm), σ is the compression strength (MPa), E is the modulus of elasticity (MPa), ρ b is the density of material of balls (kg/m 3), and D is the inner diameter of the mill body (m) Generally, a maximum allowed ball size is situated in the range from D/18 to D/24 The degree of filling the mill with balls also influences the productivity of the

The important of crushing your ore and rock fine and properly is often forgotten The finer you crush, the higher your ball mill tonnage and capacity will be The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in
