As c increases, the cut sizes of both classifiers decrease rather quickly first and then barely change. When c < kg·m −3 the classifier with the swirling inlet has a larger d 50 than that with the nonswirling inlet, while when c ≥ kg·m −3 the cut sizes of the two classifiers are close to each other.

Coal, one of the most important primary fossil fuels, a solid carbonrich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in .
The raw coal flow Wc usually contains water and the coal specific heat constant Cc varies with moisture content. The heat loss of the grinding motor in the mill can be represented as, PCImot mot mot= (8) where Imot means the motor current [A] and Cmot is heat conversion constant [kW/A]. Since the pulverized coal flow equals to the raw coal
