Abstract

PURPOSE: To stabilize the operation of a roller mill by calculating from the relationship among manipulated variables of three variables, the quantity of new feed, the gas volume of a mill, and the compression force of a pulverizing roller the manipulated variables of the operation variables every moment by the values of vibration and bed thickness, and changing the manipulated variables. CONSTITUTION: A signal detected by a vibrometer 11 installed in a mill body, a signal from a bed depth meter 13 disposed on an arm 12 of a pulverizing roller 5 and the mill body, a signal from a weigher 15 installed in a new feed supplying device 14, a signal from a tension pressure gage 17 installed in a pulverizing roller tension pressure adjusting unit 16, and a signal from a mill gas volume measuring device 19 installed in a bag filter outlet duct 18 are sent to a controller 26 through their respective filters. And the manipulated variables of the new feed quantity, the pulverizing roller tension pressure, and the mill gas volume are calculated, and according to the calculated values, the above device 14, unit 16, and a damper opening degree adjusting device 20 for adjusting the mill gas volume are automatically controlled.
