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, the capital costs and maintenance costs, and considerations for licensing.
Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
capability can be used to increase the pulverizer and boiler capacity with the present coal or to maintain the present boiler load with a coal that is more difficult to pulverize. At Danskammer, the existing pulverizer capacity was increased by more than 15 percent while the coal particles larger than 50 mesh were essentially eliminated.
