The operating costs of breaking coal particles into fine powder, to achieve optimum combustion for the boilers in a power plant, are made up of power input to carry on an energy intensive comminution mechanism and to overcome friction losses within pulverising machines. The operating costs also include the cost of the replacement of the processing system's components due to wear.

in terms of plant yield. In most cases, a higher overall plant yield may be realised by producing the coarse and the small coal at slightly different product qualities4,5,6. The difference in liberation between the coarse and the small coal very often results in the small coal exhibiting better washability characteristics than the coarse coal.
