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 …

Figure 3 presents a log-log plot of feed-size breakage rate function values, k 1, plotted against measured P/H values for: (a) the dry ball milling of dolomite in a 25.4 29.2 cm mill with different ball loads and mill speeds (Herbst and Fuerstenau, 1973); and (b) the dry ball milling of limestone in different sizes of mill (Siddique, 1977).

Vertical Ball Mills. When lime or water quality is poor and/or when lime consumption rates are high, STT designs slaking systems utilizing a vertical ball mill. The total grinding process of a vertical ball mill utilizes all residual reaction value, virtually eliminates grit disposal problems, and significantly improves lime usage efficiency.
