INTRODUCTION. AG or SAG mills have been in use in comminution circuits since the 1950's and are considered a mature technology in most countries. However, a reasonable number of recent SAG mill based projects have under-performed and not achieved throughput targets under their design conditions.

Ausenco performed a number of trade-off studies to determine which arrangement would return the optimum project net present value (NPV). These studies considered the use of a single gearless SAG mill, with installed power between 20,000 and 26,000kW, against two lines of pinion-driven SAG mills,

Ausenco is also a leader in optimising energy consumption in comminution circuit design. A paper co-authored by Ausenco to be presented at the 2018 Mill Operators Conference in Brisbane in August will highlight energy efficiency improvements at a major processing plant in Australia. We are also working with major mining house partners in …

The specific energies of the SAG and ball mills were determined using AusGrind (Ausenco's in-house software) (Lane, Foggiatto, Bueno and McLean, 2013 and Morrell's ) method. SAG mill specific energy was a function of the inverse of the Axb value, the mill geometry and the mill operating conditions.

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 required mill equipment was then sized using the Ausgrind design tool for two different criteria – case 6 (traditional approach) and case 10 (Monte Carlo). The selected mills for each case are presented in Table 7. Table 7 – SAG and ball mill equipment selected for different design criteria. Design Parameters.
