While other grinding require closed circuit cyclones and high recirculating loads the IsaMill™ achieves a much steeper product sizes distribution in only a single pass. Feed to the IsaMill™ passes through 8 consecutive grinding stages between the discs before it reaches the internal classifier.

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph

An increase of over 10% in mill throughput was achieved by removing the ball scats from a single-stage SAG mill. These scats are non-spherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates

The recirculating load in a ball mill circuit affects the final product size as well as the formation of scats/ejection of balls from the ball mill. The variables in a ball mill and cyclone should be optimized continuously to maintain a good recirculating load.

Are Sag Mills Losing Market Confidence. Sampling poor testing protocols inappropriate interpretation of data and definition of design criteria wrong mill siing methodologies poor project management decisions or a combination of these inefficient operation of the ball mills due to high circulating load

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.

2 AG mill + a recycle crusher Competent ore - relatively homogenous (the recycle crusher is used to balance the rate of impact breakage within the circuit) 3 SAG mill (8 – 15% ball charge) Variable competency ore 4 High ball charge SAG mill (15 to 25% ball charge) Incompetent ore 5 Low ball charge SAG mill, high mill speed.

These savings come from: 1) reduced costs (by not crushing and recycling the sub-grade recirculating load); 2) increased SAG throughput (by rejecting the sub-grade recirculating load thereby opening-up additional SAG volume for more fresh feed), and 3) increased copper production (by adding higher grade, fresh feed to the process).

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
