    Sep 19 2007 · Higher breakage rates were noted with cylpebs than with balls. Furthermore it was found that the primary breakage distribution function is dependent on the feed size (i.e. non‐normalizable) but independent of the grinding media shape. The effect of grinding time on the product size distribution has also been investigated.
