MoreThe 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 ...

MoreBond work index value of these components mixtures is greater than the Bond work in-dex of harder components, clinker. Oner (2000) have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass propor-tions. He found out that these values are always lower than the Bond Index obtained
