• ### Bond Work Indexan 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 3.10) a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

• ### Technical Note Why is the Bond Ball Mill Grindability Test

The Bond Ball Mill Grindability Test (Bond 1952 1961) gives the Bond Ball Mill Work Index. This Index expresses the resistance of a material to ball milling the higher the value of the Bond Ball Mill Work Index the more difficult it is to grind the material using a ball mill. This Index is widely used in the mineral industry for
