This presented a challenge when it came to pulverising it. Before fuel at the power station can be combusted, a set of mills pulverises it into a fine powder using a ring of rotating, heavy-duty balls. This fuel powder is then dried inside the mill with a mix of hot air drawn from the boiler house and cool air.Mainly there are three types of pulverizer used in industry: the slow speed mills like ball tube mills, the medium speed mills like bowl, ball and race, roller mills fall in this category, and the third type is the high speed impact mill. The slow speed and medium speed mills are selected for coals ranging from sub-bituminous to anthracite. The ...

The dry coal is then transferred to the pulverising mill to pulverise the coal. The primary air is supplied to the mill to carry the pulverised coal to the burner where the secondary air is mixed to have complete combustion of the fuel. Advantages. The layout is simple. Easy in operation. Less space is required. Cheaper.The rod mill is another tumbling mill but having a large percentage of its volume (30 - 40%) loaded with steel rods. The rods are placed axially in the mill and are loose and free to move within the mill. The internal lining of the drum has a series of lifters which raise the rods and drop them at a predetermined point.
