Circuit is shown in figure1. it is commonly referred to as a sabc circuit, for semi-autogenous ball mill crusher (sabc). this circuit shows a semi-autogenous grinding (sag)/ball mill circuit where both grinding mills are in closed circuit, with the sag mill closed with a crusher to control the amount of ‘critical size’ material in the circuit.
Economic operation of the power grid, it usually had parallel capacitor, and had reactive power compensation. for example in a ball mill, it usually uses asynchronous motor when p kw e 2000 (pe is rated power), it usually uses synchronous motor when p kw e 2000. the paper used the p kw e 2000 of the ball mill, the power loading used
