A method for mill control and supervision is described that is based on measurement of the mill horsepower consumption and the bulk density of the material being ground. Control by horsepower is shown to be possible and to be a more fundamentally based scheme than other commonly used systems. A monitoring and control system is discussed that uses the relationships described to provide a visual indication of mill loading conditions that can be used effectively by nontechnically trained personnel for manual mill control or as an automatic signal for direct control interlock with programmable controllers.
