Pulverized coal producing processes are widely used in thermal power stations, cement and ironsmelting industry. Many accidents and protection techniques have been reported by former investigations [13]. Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying and

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 predetermined 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.
