SKF Performance Contracts for Horizontal Grinding Mills

After monitoring the SAG mill for just under three months, warning signs appeared in the data. An analysis of a waterfall diagram showed that sidebands had developed around the input pinion gear frequency, indiive of the wear on the gears. Data was collected in both directions and trended separately. The sidebands were seen more clearly in the reverse direction, confirming the damage.

INNOVATION [X] – Process Optimisation

INNOVATION [X] – Process Optimisation

Optimisation Modelbased control is suited to optimization of wellunderstood unit processes (SAG mills, ball mill circuits, flotation circuits, thickeners as an example). The performance is superior to that of modelfree systems (expert systems as an example) because they are capable of anticipation and thereby can predict the process response to new situations.

Typically, SAG mill control is performed with respect to bearing pressure and other process variables which are used to estimate volumetric loading in order to optimize the mill throughput. While these methods are typically effective, they can also have several shortcomings when changes in mill liners, lifter profiles (wear), ore density, rotational direction, and/or temperature occur.

plant testing and its nature is considered in SAG mills design and optimisation. In many cases the feed size distribution is even more influential than the ore characteristics (Simkus and Dance, 1998; Kojovic, 2005), but it is not considered for the design. A notable exception is the Morrell's model (Morrell, 2008, 2009). In his approach the total specific energy of the entire AG/SAG ...
