finess of coal mill

Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 6580 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is recommended (Graph below) to minimize the potential of spontaneous ignition of fine coal, which will again vary for different coal types as below:
