inlet and outlet temperatures coal plant

Coal mill hot air inlet temperatures should never be more than 600 f and the outlet temperature should not exceed 200f 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
