    The conventional wisdom is to look at the semiautogenous grinding (SAG) mill as just another grinding mill in which ball charge, mill filling, and mill speed are varied to attain maximum throughput. Liner design for the SAG was also approached more from a wear perspective rather than a metallurgical and hydraulicflow perspective.

  • Throughput optimisation in milling circuits

    SAG Mill Power SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly nonlinear and shift as the ore hardness, steel load and liner conditions change. Traditional and basic control and modelling techniques are therefore not veryfective.

  • Increase throughput and capacity in SAG mills

    Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage. With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life.
