Coal Mill Model Considering Heat Transfer Effect On Mass

Feed belts (distributors) then transport the coal to the coal mill, where it is ground into dust and blown into the boiler. In order to ensure the fuel supply to the boiler in periods of full load, and especially low load, three redundant measuring systems are employed per feed belt.

Coal mill hot air inlet temperatures should never be 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.
