Mill Power Draw Model Bibliography Mill power draw models are used to predict the usable power draw that a particular mill will generate. The three SAG mill models are benchmarked and reviewed in: Doll, A.G., A comparison of SAG mill power models, Procemin 2013

SAG Mill Grinding Circuit Design

Gearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing to produce the world's largest SAG mill of 42’ in diameter drawing power at 28 MW. Today, is the world leading supplier of gearless SAG mills operating globally.

sag mill power consumption

The SAG Power Index (SPI) test (Starkey & Dobby, 1996) uses a benchscale SAG mill test to - determine the specific energy of an industrial SAG mill. The test is operated in closed circuit and the time required to grind the material to a P 80 of 1.7 mm is used to predict AG/SAG specific energy using Equation 3 and other power-based models available in CEET (Comminution Economic Evaluation .

Autogenous and Semi-Autogenous Mills

 · The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems 9.1 In an SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the

union reefs sag mill power

SAG mills use a ball charge of 8 to 21 . The largest SAG mill is 42 (12.8m) in diameter powered by a 28 MW (38 000 HP) motor. A SAG mill with a 44 (13.4m) diameter and a power of 35 MW (47 000 HP) has been designed. Attrition between grinding balls and

Unlock SAG mill capacity with process control optimization

The traditional operation of SAG mills relies on the operator to adjust the manipulated variables to maintain the target mill load and power draw. Changes to the ore hardness, feed size or ore specific gravity require an alert operator to adjust the variables while …
