If the ball mill is not subjected to cooling measures for a long time under high temperature conditions, it is easy to reduce the grinding efficiency, shorten the service life and increase the maintenance workload, which not only causes damage to the ball mill itself, but also causes the grinding products to fail and the performance is lowered. .
Mill performance is based on mill diameter and length only increases or decreases capacity. The Slice Mill is simply a mill of the same diameter as the production mill but much shorter. A Slice Mill of 72” diameter by 12” wide would replicate the result of a normal production, mill 72” in diameter as 120” long.
