Ball Mill Parameter Selection amp Calculation
Aug 30, rho s — loose density of grinding medium, t/m3. forged steel balls; p=s=4.5-4.8t/m3 cast steel balls p=4.3-4.6t/m3; rolling steel balls p=6.0-6.8t/m3; steel segments p=4.3-4.6t/m3_-filling ratio of grinding medium, when wet grinding: lattice ball mill pi = 40% – 45%; overflow ball mill phi = 40%; rod mill phi =.B. when feed size was 16mm ball consumption was high. when we used 12mm feed it reduced drastically. c. wt% solids in ball mill : at high wt% solids consumption was high. but at normal wt%solids it was low. similarly consumption depends on operating parameters which need to experienced by an operator, or do lab r&d.
