Coal Mills in Thermal Power Plant

Hence the mill capacity varies inversely with the size of the raw coal. Using smaller size raw coal feed to mill to increase the milling capacity only shift the workload to the raw-coal precrusher.Normally optimum coal size is selected so that total initial, operating and maintenance cost of precrusher and mill can be kept minimum.
