Coal from the boiler bunkers is fed under control into the mills, the feed rate being determined by the requirements for steam. Inside the mills either large steel balls or rollers run in circular tracks, to pulverise the coal to powder. This fine, highly combustible powder is blown from each mill into the boilers at some 63 tons an hour.
