ABSTRACT:
Apparatus for controlling the operation of a grinding system having a plurality of mills running in a parallel fashion, in which the operating condition of each mill is controlled such that a predetermined physical quantity, which changes dependent on the running condition, is equal to set values for the mills, and the set value for each mill is variably controlled so as to maximize the amount of pulverized material. The apparatus includes means for comparing a pulverizing amount F.sub.A per unit time of the mill under control with that F.sub.B of another mill, and controlling the set value for the mill under control so that a difference between the pulverizing amounts (F.sub.A -F.sub.B) is maximized while the set value for the other mill is fixed, whereby the set value of the mill under control is automatically optimized.
