The pursuit of high-efficiency pulp discharge systems by mill and liner suppliers is a testament to the potential upside of open-ended milling. Maximized slurry transport and minimized slurry pooling. The OED Mill has been designed to maximize slurry transport and minimize slurry pooling. This increases throughput capacity and improves grinding ...

The SAG mill disch arges onto a trommel, the coarse material from the . ... The pebble stockpile material is fed to one or both of the cone crushers which discharge onto the SAG feed .

Feed and discharge The feed includes the trunnion liner and feed chute with support, as well as a feed seal to provide a safely sealed, low-maintenance setup. The standard discharge setup is a trunnion liner and reversible, disposable steel trommel with discharge housing. 6 Mill diameter [m] 1 0 2 3 4 MH Rod mill MH Ball mill MH SAG mill

SAG/AG milling option is ideal for starter projects with significant exploration and expansion potential. Currently a number of the largest SAG mills designed are installed in single stage configuration. This paper discusses the challenges associated with the process design of single stage SAG/AG milling circuits, the design flexibility required to

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multi-input multi-output (MIMO) controller, is very suitable for this purpose. ...

Commissioning of the 375 ktpm Autogenous Milling Circuit - SAIMM. was designed to treat the main mineralised zone (MMZ) arising's from both underground and commissioning, and compares initial operating performance to the design expectations. . a single 23ft x 31.5ft, grate discharge ball mill also fitted with dual 5.2MW drives.

The SAG mill has a trommel on the discharge end of it. Oversize is returned to the mill by a bucket wheel and water jet. Trommel undersize was pumped to a vibrating screen where the screen oversize was sent back to the mill and the undersize was pumped to the cyclone circuit. Figure 2 shows the flowsheet for line 2 with only the trommel,

SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a 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 28 MW (38,000 HP) motor.

The same underlying model is used for SAG and ball milling, with minor differences for the way the charge density is calculated and whether the mill is a grate discharge (most of the SAG mills) or overflow discharge (typically a ball mill). Within the classification, there are also two versions of the Morrell C-model:

SAG Mill Discharge - Trunion Liner Challenge Goal Provide an emergency temporary repair to bridge the 6-week lead time to get a new steel liner by repairing the existing one with an ARC coating in order to meet production goals Root Cause Worn rubber boot seal allowed abrasive mill media and ore into liner housing, wearing away ID of housing.

Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel. SAG mills grinding media includes some large and hard rocks, filled rate of 9% – 20%. SAG mill grind ores through impact, attrition, abrasion forces.

The comparison results in Table 1 show that the service life of semi-autogenous mill liner is increased from 2800 h to 4300 h, the service life of ball mill liner is increased from 5000 h to 7200 h, the production capacity is increased by 50%, and the discharge fineness of SAG mill is reduced by 3.71%.

Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two.

19 x 28 ft (5.9 x 8.5 m) Morgardshammar SAG Mill with 3750 HP (2,800 kW) motor. The mill consists of the following major components: - Mill shell - Mill Feed End Head, Mill Discharge End Head - FE Mill .

Gearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing to produce the world's largest SAG mill of 42' in diameter drawing power at 28 MW. Today, is the world leading supplier of gearless SAG mills operating globally.

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 .
