MILLING CONTROL & OPTIMISATION - Mintek

Figures 8 and 9 on the right show results from a gold plant’s SAG mill achieved with MillStar’s Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable allowing for consistent size separation and feed to downstream processes.

SIMINE Gearless Mill Drives

Fully automatic – rpms can be adjusted to the properties of the ore resulting in significantly less wear to the mill lining. The mill’s direction of rotation can be changed simply with a switch so that the wear on the liner is distributed equally from both sides. Shorter maintenance time for mills Simple control of the inching and creep-

Optimizing your SAG mill operation - International Mining

In multi-stage ABCSABC circuits the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry which goes to the ball mills for further grinding and coarse pebblesrocks which are crushed and sent back to the mill.
