Other work included structural steel design and detailed shop drawings for the SAG mill feed platform and steel platework drawings associated with the mill boil box, feed chute, and discharge hopper.
A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit. A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 5/8″ or 16mm In the image case below, strangely enough, SKD is the mill shell liner and discharge grate
Mill drive arrangement. Mill drives are generally located on the outside of the mill to facilitate maintenance. • Mill discharge arrangement. If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, …
SAG mill. 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%. The largest SAG mill is 42' (12.8m) in diameter, powered by a …
The stable discharge of particles through the hopper plays a key role in many industrial applications. In order to investigate the discharge characteristics of binary particles in a rectangular hopper with an inclined bottom, the discrete element method (DEM) was used to simulate the discharge process. The accuracy of DEM was validated by comparing calculated and experimental values. The ...

SAG mill discharge passes through grates and screened by a trommel with the oversize being recycled by conveyor back to the SAG mill. Combined product from the SAG mill (trommel undersize) and the Ball mill discharges into a common mill discharge hopper. This product pumped to a set of cyclones with the underflow being directed back to the Ball ...
The mill's SAG/ball/flotation circuit was initially designed for 35,000 mt/d. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mt/d. However, the increased circulating load led to overloading of the original …
Developments in SAG Mill Design and Operation Over the last few years, SAG mill manufacturing technology has advanced rapidly. The bounds of mill size have been pushed from two directions. Firstly, the advent of ring motors has removed the constraint applied by the power that a …

Each grinding train consists of a semiautogenous grinding (sag) mill and ball mill with associated cyclones, pumps, and flash flotation cells. new feed from the reclaim system is conveyed to the sag mill feed chute. the sag mill discharges via a trommel and vibrating discharge screen into a dedicated sag discharge hopper. the.
The SAG mill feed conveyor transfers the crushed ore into the SAG mill for grinding. The SAG mill reduces the ore size to the consistency of coarse gravel, using a wet-grinding process. Discharge from the SAG mill is significantly wet and has the consistency of slurry. The slurry is discharged through a screen to remove any oversized material.
In this configuration, the water addition to the discharge hopper is varied to maintain a constant feed density to the cyclones. The pump speed is varied to maintain a limited range of levels in the discharge hopper. The mill is controlled to maintain a constant mill weight and circulating load (see control philosophy above). ... The SAG mill ...
Control of circulating load (cyclones online) based on mill discharge hopper level is being replaced with implementation of constant pressure control on both SAG and ball mill cyclones to stabilize circulating loads. SAG mill grate design causing flow restrictions and slurry pooling. Investigation of new grate design is underway.
The SAG mill agreement has come about as First Majestic ordered a complete new SAG mill package, which, Condor says, is now superfluous to its requirements. The SAG mill has a mill diameter of 24 ft (7.3 m) and an effective grinding length of 18.5 ft and a structural charge mass of 315 t, …
SAG mill speed to fast for fine feed size. Solution: • Slow down SAG mill to increase the mill load to around 25%, thereby using more of the SAG power to do fine grinding, not impact. A 3-5% improvement in grind size could be achieved through the control of SAG load - at the same throughput.
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).

The mill receives crushed ore and process water at a variable flow rate to achieve the correct pulp density. Lime, zinc sulphate and sodium metabisulphite (SMBS) are also dosed to the ball mill to condition the ore prior to the flotation circuit. The ball mill discharge passes over a slotted trommel screen with an aperture size of 10 mm x 25 mm.

the SAG mill feed chute via the primary flash flotation cell and the cyclone overflow gravitates to the ball mill discharge hopper. This slurry, along with the ball mill discharge, is pumped to the secondary cyclone cluster including twelve 250CVX cyclones which are designed to achieve a P80 of 45µm.
The SAG mill discharge screen undersize will gravitate to the mill discharge hopper, where it will be diluted with process water and pumped to the classifying hydrocyclone cluster. The combined cyclone overflow stream, with a nominal pulp density of 42% w/w solids, will gravitate to the trash screen.
