Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through 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.
Coal and pre-heated primary air enter one or both ends of the mill from a crusher/dryer or feeder. As the mill rotates, the balls cascade and pulverize the coal by impact and …
