    Sep 10, 2015· Coal Mill Temperatures. 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.
