However, particle size distribution is again a problem, and roll presses are now increasingly popular as a pre-grind process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system.
particle size distribution curve. By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6 B It should be noted, however, that operation to achieve a wide particle size distribution (low n-value) has a cost.
