Apr 08, 2004· A better solution is to exchange the static classifier for a dynamic (or "rotary") type. 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 to eliminate almost all the coarse fraction (>300 µm) from the supply of PF to the furnace.
