Coal pulverizer The Babcock & Wilcox Company

One type of known coal pulverizing mill (pulverizer) is a slow speed, roll-and-race-type pulverizer that uses three large-diameter grinding rolls to crush the coal. Primary air enters the pulverizer through a radial inlet duct, moves into a low-velocity air plenum, and is then accelerated and oriented by a series of stationary passages in a ring that surrounds the grinding zone.
