Coal dried with air at 250–350°C for milling in low, medium or highspeed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding, and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging.

The fuel injector is designed to introduce the dispersed coal particles in a medium of air into the furnace. The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from to with a typical value of
