It describes the advantage of using tower type matched with fanmill for lignite fired boiler-fan milling system has good drying capability and good adaptability for raw coal moisture.
But it has not been long to use the middle-speed mill and fanmill in thermoelectric generator units in China, and there are still big gaps between the simulation model and the actual behavior.
Because of carry long liters fan chamber and shorten the pulp role in grinding machine, so stay time in grid ball mill, say again forced row ore type mill.
