Development of a Multisegment Coal Mill Model Using . - IEEE Xploreances. The work presented in the paper focuses on modeling E-type vertical spindle coal mills that are widely used in coal-fired power plants. An evolutionary computation technique is adopted to iden- tify the unknown model parameters using the on-site measurement data. The identified parameters are then validated with.vertical spindle e type coal mills,Pulverizer - WikipediaSimilar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found . Depending on the required coal fineness, there are two types of classifier that may be selected for a vertical roller mill. The dynamic classifier, which.
