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
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 SAGAG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
The Copper Mountain SAG mill is 10363 mm 34 feet in diameter and 6096 mm 20 feet long. It is a grate discharge mill with an inside diameter of 10363 mm 34 feet and a grinding length of 5334 mm 17.5 feet. The mill is driven by two 8,500 horsepower ABB motors. Figure 2 - The 34 x 20 SAG mill
down menu. The mill diameter input relates to the inside-shell dimension. The model actually requires the inside liner diameter and hence the liner thickness must also be input. The required length to be input depends on whether the mill is an overflow or a grate discharge machine. In all cases AG and SAG mills
Mar 15, 2021 The SAG Mill has a mill diameter of 24 feet and an Effective Grinding Length EGL of 18.5 feet and a structural charge mass of 315 metric tonnes.
consideration of a larger mill installation with diameter at the design stage. Between 2001 and 2008, a limit of 22 MW was placed on SAG mill drives as GMDs by some operators and principal motor designersmanufacturers until the reasons for known problems in design or manufacturing were better understood and resolved.
Feb 01, 2019 The impact of the shape representation used for rock particles in a DEM model of a SAG mill on charge dynamics and energy utilisation is investigated. A 1.8-m diameter pilot scale SAG mill which includes realistic end walls and a discharge grate is used. This size of mill is used for scale-up and design processes for industrial SAG mills so understanding the effect of approximating the ...
Sep 20, 2018 A Discrete Elements Method DEM study of load movement within a SAG mill 12,192 7620 40 25 in normal operating conditions is performed. The purpose is to determine how the geometry of the lifters affects the kinetics of the load inside the mill. Specifically, the changes produced by the incorporation of inclined lifters and spiral or helicoidal pulp lifters to the kinetics are ...
Oct 15, 2020 The SAG mill will be charged with high chrome grinding media at a diameter of 125mm by means of the grinding building hoist and ball kibble. The discharge of the SAG mill will be received at a cyclone feed hopper and pumped to the cyclones.
Jan 10, 2021 done in a SAGball mill circuit with no coarse recycle classification of the SAG mill discharge. The primary grinding mill is an 18 ft. diameter x 9 ft. EGL, 1500 HP variable speed SAG mill and the secondary mill is a 13 ft. diameter x 21 ft. long, 2000 HP fixed speed, ball mill.
AGSAG Mill Liners. We have supplied rubber pulp lifters for SAG mills up to 40 ft in diameter. We are pioneers in the design of both radial and curved pulp lifters, also design and manufacture Rubber PolyStl grates and discharge systems. Mining.
Conventional straight-radial semiautogenous grinding SAG mill pulp lifters suffer from incomplete discharge of the rockportion of the charge. The resulting backflow of undischarged rock limits ...
The primary ballSAG mill discharge is one of the most severe duties in mineral processing. The suction wearplate is subjected to rapid wear due to high solids concentration and the coarse nature of the slurry. Goulds developed a proprietary process to locate and mold ceramic rods into the rubber liner for the optimum combination of hardness
Nov 26, 2019 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.
AGSAG Mill Liners. We have supplied pulp lifters for AGSAG Mills up to 40 ft in diameter. We are pioneers in design of both radial and curved pulp lifters and discharge systems. We also design and manufacture rubber and PolyStl grates, lifter bars, shell plates, end plates and all other associated grinding mill liner components. Learn More
to specific ballSAG mill operations. Mill capacity, ball size and other parameters are used to select and specify the design features for each installation. Besides removing worn grinding media from the ball mill discharge and saving energy, trunnion magnets have other advantages that appeal to SAG mill
size distributions in AGSAG mills. The existing models and understanding of grate discharge and classification are known to be flawed and have been identified as one of the key limitations in AGSAG modelling. The aim of this thesis is to improve on the current understanding of discharge in the SAG
The capacity of the SAG mill is related to lots of factors such as feed size, size distribution, discharge size and grindability, etc., and it should be confirmed according to the actual situation. SM4014means it is a dry mill.
