Coal Pulverizer – Power Plant Pall Corporation
The four most common coal pulverizers types are: Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.

Coal Pulverization System: Explosion Prevention and Process
Pulverized coal producing processes are widely used in thermal power stations, cement and iron-smelting industry. Many accidents and protection techniques have been reported by former investigations [1-3]. Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying and

COAL BASED THERMAL POWER PLANTS: COAL MILLS FOR THERMAL STATIONS
2011.12.13 Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh (0.075 mm) and 99 % will pass through 50 mesh (0.300 mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.
