Mass balance control of crushing circuits

easily regulated with classic control methods. To complete the circuit mass balance control strategy, it is necessary to define a control strategy for every feeder in the circuit. These controllers will then manipulate the in-circuit and circuit output flows, whilst the mass balance controller only manipulates the fresh feed input flow.
