Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Amstar SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

However, the SAG mill specific energy is calculated using proprietary models and the specific ball milling specific energy is the differential between the SAG mill and total specific energy requirements. This method acknowledges the limitations of using the P 80 of the transfer size between the SAG mill and the ball mill.

The testing was conducted in a large copper ore mine which had a SAG mill in a closed circuit with the cyclone cluster. The trial tested one ® 2 650 in a 6-place cluster of existing ® cyclones and saw an improvement of up to 48.5% in circulating load and 31.7% in water bypass versus the original cluster.

In this example, the OWi of the SAG mill was found to be 30% higher than the ball mill, thus suggesting that the SAG mill was less efficient than the ball mill. The apparent inefficiency of SAG mills when using Bond analysis is widely understood to be due to the difference in the slopes of the size distributions.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
