Fote's coal mill has been improved. The drying bin of the Fote coal mill has been shortened from the original 3m to 2.1m, and the grinding silo is extended by 0.9m, so that the length ratio between the drying bin and the grinding bin can reach 1:2.81. Such a change can grind coal pieces more fully, and can also grind inferior coal finer in ...
