three Riley Power double-ended ball tube mills. Each mill can provide 65 tons per hour of pulverised coal to the boiler, or a total of 195 tons per hour, per boiler. Because the ball-tube mills have outlets at each end, with a classifier on each outlet, two sample points were needed on each mill. For enhanced reliability, a redundant configuration

Optimization of mill performance by using

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
