Autogenous and Semi-Autogenous Mills | FL

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. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

Loveday/Barratt SAG model

The power numbers that Barratt published are based on mills with 'typical' cone-ends (probably 15° to 25°). A flat-ended (shell-supported) mill is expected to have 5% less power draw. Model Form. Loveday's equation is: Where: P is the power evolved at the mill shell, kW; P N is the empirical power number read from the chart below
