Ball Mill Circuit Operation. 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 sagball 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.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
Ball Mill Circuit Operation. The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media as well as a lot of noise most of the energy useless lost during ball mill operation leading to low it efficiency but even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
