Grindability of mixtures of cement clinker and trass

Nov 01, 1998 The Bond method of grindability was applied to clinker and trass and to their mixtures. Kinetic experiments also were carried out in the Bond ball mill with each component and the mixtures to obtain a better understanding of the interactions taking place in mixture grinding. The Bond work indices of mixtures were not simply weighted averages of

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
