Bond Work Index For An Ultrafine Mill

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 3.10), a question arises as to whether this practice will alter the ball mill work index (bw i) of the material.bond work index for an ultrafine mill,bond work index for an ultrafine mill jjvastgoed.nl. bond method for ball mill work index test. bond work index an overview sciencedirect 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 ( mesh), thus determining the ball mill work index (wi b or bwi).get price.
