Abstract

A method and apparatus for controlling the operation of a rock crusher and feeder such that the rate of supply by the feeder to the crusher hopper is kept within carefully controlled parameters and such that the power level at which the crusher operates is maintained within a narrow range at the optimum operating range of the rock crusher. A microporcessor having a first PID control loop receives an input signal from a transducer sensing the power draw by the crusher motor and a second PID control loop receives a signal from an analog level sensor measuring the level of rock in the hopper. The first PID compares the sensed power draw with a selected maximum power draw and produces an output signal proportional to the difference between the sensed power draw and the selected power draw. The second PID compares the sensed level in the hopper to a selected or desired level in the hopper and produces a signal proportional to this measured difference. The signal from the first PID and the signal from the second PID are transmitted to an arbitration routine for comparing the signals. The first or second signal calling for the lower feeder speed will be transmitted to the feeder variable speed drive.
