    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 was chosen with two sample points on each classifier, giving four samples per mill.
