Bond Selection for Production Grinding Norton

2017-7-20  Abrasive product bonds are generally classified as organic (resin, rubber, and so forth), vitrified (glass or glass-ceramic), or metal, with each type of bond offering its own unique benefits. Organic or resin bonds offer significantly more compliance (the opposite of stiffness) relative to the other types, and are able to withstand harsh grinding

Bond Selection for Production Grinding Production

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 being ground and hence have an impact on the energy used in the mill for grinding.
