SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44 ...

The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, …
SAG mills are used predominantly with feed material with a larger max lump sizes (from primary crushing plant typically in the max lump size range 150 mm to 300mm and a psd to follow) and the ball or rod mills are for smaller feed lump sizes. The final product size depends on the retention time and grinding capability of the type of mill.
SAG mills and AG mills differ in their power consumption, which is an important factor to consider when selecting between the two. Subheading 1: SAG Mill Power Consumption. SAG mills typically have a higher power consumption than AG mills due to their larger diameter and longer length.
A variable speed primary mill provides a method of compensating for variations in ore hardness and gives a much more flexible grinding circuit. Although there is no such circuit on hand today, we think it is within our grasp the technology is there to make big mills, to use sophisticated control schemes and to vary the speed of huge hp mills.

Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. 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 …
SAG mills have coarser feed sizes (sag mill feed) and process more material due to the bigger diameter and length to diameter ratios. Ball mills employ steel balls as …
These mills use steel balls that go up to 6.5" in diameter and have a high risk of fracturing the internal linings of the mill. Potential impacts of the steel balls against the mill lining will be generated if the rotational speed of the mill is greater than that required for the ball to fall on the ore rock and fracture it.

SAG mills play an important role in copper ore mining by efficiently breaking down large chunks of material into manageable sizes while also using less energy than traditional methods. The Grinding Laws and Machines. Grinding is an essential process in the mining industry, and it involves breaking down large pieces of ore into smaller fragments
The instrumentation installed on a SAG mill is integral to control. For example, the mill load and noise sensors are instruments that provide essential information for an optimized SAG mill operation. Insufficient understanding of the ore characteristics and feed composition can result in an ineffective SAG mill operation.
SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range. Typically a SAG mill weight measurement, by either bearing pressure transducers or load cells, is used as an inferred measurement of volumetric filling. To maintain volumetric filling within a set operating range the SAG weight setpoint use for …

The cradles need to be lifted up to sit under the shell then jacks placed under the cradles. You sit the jacks on some big thick steel plate to dissipate the load a bit otherwise could punch through the concrete. You will insert the jacks between the cradle and the shell and then if you lift the cradle up off the concrete plinths the same gap.
