Dewatering.—In small mills there is a definite trend to direct filtration or dewatering without thickeners. As most plants of this type are handling relatively coarse grind ores, direct filtration of concentrates gives a low moisture content. The saving in capital cost for thickeners, diaphragm pumps, and larger buildings is considerable.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
