Bond Method For Ball Mill Work Index Test Bond Work Index an overview ScienceDirect Topics. The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 m (325-100 mesh), thus determining the ball mill work index (WiB or BWi).

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
