In the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone. The tube mills have a large circular drum, with adequate ball charge, which is rotated at about 70% of the speed at which the ball charge would be held against the inner surface by centrifugal force.

The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling systemthrough coal feeder into a pre-determined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel. …
