Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
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 consists of a hollow cylindrical shell rotati

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 abrasion the particles between the balls.
Ball Speed is the speed of the golf ball immediately after impact. Ball speed is created by club speed and impact. Bad impact such as shots hit on the toe or heel will reduce the potential ball speed. "Glancing blows" created by hooks, slices, and hitting too much down on the ball can also reduce the potential ball speed.

Simplifying wet grinding with AG/SAG mills AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.
