The geometry of a mill with conical ends is shown in Figure The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm () The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an
· The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
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 typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

· Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
Hertz theory and one where theory and practice have proven to agree well. It also forms the basis for theories on ball bearing life and friction. Generally, the contact conditions between the inner ring raceway and ball is more severe than those between the outer ring raceway and ball.
