• Improving Coal Pulverizer Performance and Reliability

     · This mill uses hydraulically loaded verticalrollers resembling large tires to pulverize rawcoal fed down onto a rotating table. As thetable rotates the raw coal is pulverized as itpasses underneath the rollers. Hot air forcedthrough the bottom of the pulverizing cham-ber removes unwanted moisture and trans-ports the pulverized coal dust up through thetop of the pulverizer and out the exhaustpipes directly to the burner. The more recentcoal pulverizer designs are Vertical RollerMills. Figure 2 shows a cutaway view of aBabcock and Wilcox MPS Pulverizer.
