Grinding Mills: Ball Mill Rod Mill Design mon types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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 particle size measurement device and size control cyclones.

When the ball mill is rotated , the balls are carried by the mill wall nearly to the top Balls are released by the gravitational pull and drop to the bottom and picked up again Centrifugal force keeps the ball in contact with the mill wall.

Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility cryogenic, wet and dry grinding at room temperature makes the CryoMill the ideal grinder for quantities up to 20 ml.

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. Then, discharge of ground material performed

For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume .
