Oct 01, 2014 After some time, because the coal is feeding into the pulverizer at a constant rate, the coal will accumulate in the mill, and the power consumption of the mill will increase to a limit that the mill cannot handle. Additionally, the load on the mill will have to decrease along with a reduction of the power produced by the PP.
