In thermal power plant, pulverization of coal is carried out by coal mill. Raw coal is moved from the storage to the mill by conveyor mechanism. The type of coal mill envisaged for our model is bowl mill which is shown in Fig.1. Raw coal is introduced near the centre of the grinding table through the coal feed pipe.

levels. Major contributors to this mix are coal and gas based thermal power stations. By the end of 11th Five year plan, thermal power plants alone contributed 85% to the total installed capacity of thermal power plants, as against 14% of gas-based power plants. In fact, coal based power accounts for a major share to total actual generation too.

In modern thermal power plants coal grinding mills are an important and very frequent subsystem. As time passes the grinders in the mills become depleted and the functionality of these mills decreases. Because of that the mills need to be stopped periodically, every 1500 hours, so they can be checked and, if necessary, repaired.
