ABSTRACT:
A control system (44, 112) particularly adapted to be cooperatively associated with a mill (10) and in particular a roller mill (10) of the type that is operative to effectuate the grinding and/or pulverization of solid materials. When so employed, the subject control system (44, 112) enables the roller mill (10) to be operated over a wide range of varying levels of output of pulverized material, while yet ensuring that both the proper air/solids ratio and the desired degree of fineness of the pulverized material are being maintained. To achieve this result, the subject control system (44, 112) is operatively connected in circuit relation with the feed means (12) that supplies to the roller mill (10) the material that is to be pulverized therein, with the drive means (20, 22) through which the mill (10) is driven, with the classifier means (38) that effects a separation of the pulverized material according to fineness, and with the means which receives the output from the roller mill (10).
