摘要： An improved coal pulverizer associated with a rotary classifier which can be operated always safely regardless of change of a species of coal, is disclosed. In a coal pulverizer associated with a rotary classifier which is applicable to the use of a pulverized coal burning boiler or the like, there are provided a function generator 1 having a signal C.F. representing a coal feed rate input thereto for outputting signals representing a preset proper range of a motor current of the coal pulverizer corresponding to the coal feed rate, a computing unit 2 responsive to a signal A representing the same motor current and signals representing a proper range of the motor current for outputting a command signal to maintain a number of revolution of the rotary classifier when the motor current represented by the motor current signal A is within the proper range while outputting a command signal to decrease or increase a number of revolution of the rotary classifier, respectively, in the case where the same motor current has increased beyond the proper range or in the case where the same motor current has decreased beyond the proper range, and a rotational speed controller 3 having the command signal input thereto for regulating a number of revolution of the rotary classifier.
