Ball Mill Power/Design Calculation Example #2 In Example No.1 it was determined that a 1400 HP wet grinding ball mill was required to grind 100 TPH of material with a Bond Work Index of 15 ( guess what mineral type it is ) from 80% passing ¼ inch to 80% passing 100 mesh in closed circuit.

A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to be

SUMITOMO KAGAKU 2007-II 2 Design Method of Ball Mill by Discrete Element Method of the balls are in a state where they are covered with the solid materials. It appears as if balls coated with the solid materials are moving. Therefore, Kano et al.8) have simulated

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill

D esign M ethodology a) Milling Sizing The Bond’s method was used in sizing the laboratory ball mill. This method is based on two power calculation approaches used in ball and rod mill design processes due to its simplicity and workability. The first approach

material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that
