Bond Work Index

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

Classifier mills are a type of rotary impact mill (referred to above) which have the benefit of being a single machine with an integrated impact mill and classifier in the one housing. The CLM mill is commonly used for multi-stage, closed loop grinding and is ideal for products with properties of a more challenging nature and/or requiring a tightly controlled particle size distribution (see ...
