power required to drive the ball mill is 0.2025 horsepower, the length of the mill at a fixed mill diameter of 210 mm is 373 mm, and the required shaft length and diameter are 712.2 Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is Ball Mill an overview ScienceDirect Topics

Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry grinding systems. Their average relative grinding ball consumption is approximately as follows: Chrome: high-carbon: cast-ironThe roller mill minimizes such costs by precisely reducing feed materials with an average particle size up to 3⁄ 4 inch to a uniform average size typically between 100 and 2,000 microns. The roller mill’s ability to reduce materials to a uniform particle size provides more control of product characteristics and minimizes waste, as shown inRoller mills: Precisely reducing particle size with greater

Assuming the input values are in millimeters and KC is in Mpa (N/mm 2) the result should be divided by 60,000 to get the power in kW.It seems certain, however, that the ball-mill will crush to 200 mesh a considerably greater tonnage when the proper classification is provided. Since in previous tests the mill has crushed 7½ T. per hr. from ¼ in. to 200 mesh, it seems possible that it will crush at least 8 T. per hr. from 48 to 200 mesh.Ball Mill Grinding Theory Crushing Motion/Action Inside
