Optimizing your SAG mill operation - International Mining

Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm). Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed circuit with classifiers whose circulating loads reach as high as 400-500%.

Mill power draw models - SAGMILLING.COM

The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits re-circulation of pulp back into the mill.

SAG mill | 3D CAD Model Library | GrabCAD

A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing. The Sag mill is usually part of the primary stage in the grinding process. Pieces of raw or fairly reduced materials are ground into smaller pieces for further processing or sorting.

Industrial Grinding Estimation of Blended Ore from Porphyry Copper Deposit

As a result, the measured AG/SAG mill power draw often varies widely with time. This is one of the significant differences in operation between the AG/SAG mill and the ball/rod mill, power draw of the latter being relatively stable. In response to the variation in feed size and hardness, the mill feed rate has to be changed significantly [7].
