how roller coal mill works soyezvus. modeling and parameter identification of coal mill citeseerx. the coal mill used in the coal-fired power plants is modeled in view of the controller design rather than the educational on the rotating table and it is ground under the roller. the while the mill operates, the actual body temperature is mill feeders: feeders for coal mill are generally installed directly under hoppers with rod gate in between. the feeders are generally to long and discharge on to conveyor or feeding chute to mill. for coal mill feeding, table feeders, belt feeders, chain feeders and weigh feeders have been used.the oktm mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills. our atox coal mill has large rollers with great grinding capability of all types of coal
