the pulverizer system design lies in the selection of air to coal ratios to handle the specific coal property. Figure 9 shows a typical ball tube mill arrangement including crusher dryers. Figure 10 illustrates changes in air coal ratio necessitated by different coal
Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal

coal pulverizer designs are Vertical Roller Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer. RingRoll and BallRace Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a RingRoll Mill
Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal
