Coal Grinding - Cement Plant Optimization

Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 65-80 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:

10/9/2015· Coal mill hot air inlet temperatures should never be more than 600 F and the outlet temperature should not exceed 200 F on Raymond coal mills. If the flow of raw coal to the coal mill is interrupted for any reason (for example: plugging, failure of the coal feeder, etc.), the outlet temperature of the coal mill can quickly climb to dangerous levels.
