4. ROLE OF MILLS • Produces Pulverized coal 80% of which passes through 200 mesh • Air mixed with Pulverized coal (PF) is carried to the coal nozzle in the wind box assembly. • PF from coal nozzle is directed towards the center of boiler burning zone • Preheated secondary air enters boiler and surrounds the PF and help in combustion. 5.

In the ballandrace mill ( Fig. ), balls are held between two races, much like a large ball bearing. The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.
