Jul 07, 2017 In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed between two moving surfaces namely balls and races. A worm and gear drove the upper stationary race, and the lower rotating race holds the balls between them.

coal pulverizer or mill systems. The studies showed that there is an emergence of low rank, high reactive coals as a base fuel for power plants which is resulting in an increase in pulverizer system fires. Also, the EPRI study concluded that reducing the frequency of fires would reduce the risk of coal dust explosions. Unfor

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.
Likewise, they work together to eliminate the root causes of failure, as is the case with the ball mill pulverizers, which had produced consistently high failure rates. Focus on Ball Mills. Ball mills, or pulverizers, are critical to the operation of any coalfired boiler.
manufacturers of coal pulverizing equipment. The four most common types of coal pulverizers are BallTube 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
