摘要
Method for controlling flowed through during the mill drying process, in particular a pulverized coal-mill fan flowed through during the mill drying process of raw brown coal, wherein at least the parameters speed of the mill, temperature after the mill and the amount of primary air, be controlled by means ofa pilot curve (vskSpeed of the mill) for the regulation of the speed of the mill,a pilot curve (vskTemp according to the mill) for the regulation of the temperature of the mill,a pilot curve (vskAmount of primary air) for the regulation of the amount of primary air in the specified ranges by the respective pilot curves be regulated,the pilot curves (vskSpeed of the mill, vskTemp according to the mill, vskAmount of primary air) in each case depending on the determined carbon throughput areand the mill speed-pilot-curve (vskSpeed of the mill) as a function of the wear state (vIs) at least one of the milling of the fan mill is corrected in such a way that, as a function of the state of wear (vIs) the speed of the mill is increased, and wherein the respective pilot curves min and have max-curves.
