operating principle of the sag mill

The power draft of a SAG mill and its consequences are illustrated in Figure 2, wherein 5 days of operating data in a 32u14-ft SAG mill is plotted. The power draft of the mill is held between 6 and 7 MW, whereas tons per hour (tph) of ore feed to the mill shows wide variations between 1,000 and 1,600 tph.

Principal Consultant

SAG mill power draw models are used in mill design and grinding circuit modelling to predict how much power will be consumed by a particular mill geometry and operating configuration. The importance of conducting surveys suited to model calibration will be highlighted because the review of literature shows that survey information important to modelling is often missing or omitted.

SAG Mill Grinding Circuit Design

Elimination of the above mentioned material transport problems will allow the mill to respond truly in terms of power draw for changes in mill load which depends on feed ore characteristics. Although curved pulp lifters partially solve the ‘carry-over’ problem, they cannot eliminate the ‘flow-back’ problem.

Ball Mill Critical Speed

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
