Variables in Ball Mill Operation | Paul O. Abbe®

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.
