  • Dynamic classifiers: a fine way to help achieve lower emissions

    Apr 8, 2004 And the latest generation of dynamic classifiers is indeed proving to be a good way of improving the fineness of the ground coal leaving the mill, with the potential . Analysis of the results shows the mill pressure differential and the mill power consumption are a little higher with the dynamic classifier fitted.

    mill operation. The raw coal mass flow is introduced into the mill and it generates unpulverized coal mass. Some coal mass is converted into pulverized mass through grinding and the pulverized coal mass flow is generated by the air differential pressure. The dynamic equations for coal mass can be expressed as c c c c. dM.
