Ball Mill

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.

Ball mills in HPGR-Ball mill circuits tend to have more installed capacity than their counterparts in AG/SAG-Ball mill circuits. This is because the product size distribution from AG/SAG mills tends to have more fine material than the HPGR circuit product ( Morrell, 2009, Morrell, S., 2011 ) and hence need less ball mill power.
