Impact of Pulverizer Performance
(B&W) MPS-type coal pulverizers, a form of vertical air-swept pulverizer in which coal is fed from above onto the center of a rotating table. Centrifugal force uniformly feeds the coal outward, forcing the coal under spring -loaded rollers or "tires," which reduces the size of the coal. Figure 1-1 shows a cutaway of an MPS-style mill.
