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.

As the shell of a ball mill is rotated, its grinding balls move in a cataracting mode, hitting on the powder bed, and cement clinker particles are broken down to smaller sizes. In closed-circuit mode, ball milling operation and external …

The standard method for sizing secondary ball mills (usually the overflow type) in AG/SAG circuits follows published mill supplier information with aspect ratios in the range 1:1.5 to 1:2.0, depending upon product sizing and pulp flow, i.e., the highest expected circulating loads (Morrell, 2001). The applied net power, calculated from testwork

This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 µm). Furthermore, the operating capacity of the ball mill has reached 90% capacity, running at near full load.

Each nest underflow is directed to one of the two 6.7 x 9.7 m ball mill, equipped with 8,5 MW motor single pinion fixed speed drive. Targeted P80 of hydrocyclone overflow is 0.21 mm at 40% solids. Flotation and Regrinding The hydrocyclone overflow from each ball mill circuit feeds the rougher stage consisting of seven 160 m³ tank cells.

JKSimMet allows construction of mathematical models of circuits of interest by employing data analysis techniques including mass balancing and model calibration. JKSimMet uses the calibrated models to conduct simulations to investigate and compare different machine settings (e.g. ball load or vortex finder diameter) or even modified flowsheets.

As a primary ball milling operation, the proposed circuit would require a finer crushed ore compared to the present feed supply that is specified for the existing SAG-Ball mill configuration. The study was conducted to assess the capability of the comminution circuit to operate at the proposed reduced throughput.
