### The operating principle of the ball mill

Feb 8, 2017 The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and

If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed" and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind

Chat Now### Ball mill Wikipedia

A ball mill is a type of grinder used to grind and blend 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 consists of a hollow

Chat Now### Variables in Ball Mill Operation Paul O. Abbe

Ball Mill Media and Operations. Solids loading is another variable that is critical to optimal mill performance. The principle of mill operation is the impingement of the solids between pieces of media. The majority of media motion and milling occurs on the surface of the bed of media where the media is cascading. If there are
