## Bond Work Index an overview | ScienceDirect Topics

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 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

## Bond Work Index Procedure and Method

This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory If you
