Oct 16, 2015 Perhaps by making the device bigger, or at least more expensive should suffice. TEs upgrade system just does not fit well with the multi block structures. Perhaps by expanding the face(s) that accepts power the crusher can support higher voltages, by expanding the input face they would increase items processed per tick. So on, so forth.

Apr 24, 2014 Primary crusher power peaks were reduced significantly during these campaigns. In order to achieve optimal performance of downstream processes with the finer ROM, a number of changes and adjustments were made to the crusher, SAG and ball mill circuits. The resulting mill throughput averaged 4,100 tph for the three trial blasts, and plant ...
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,

Jun 06, 2016 However, open circuiting the SAG mill by feeding crushed pebbles directly to a ball-mill circuit is often considered as a technique to increase SAG throughput. An option to do both can allow balancing the primary and secondary milling sections by having the ability to return crushed pebbles to SAG feed as per a conventional flowsheet, or to the SAG discharge.
Nov 26, 2019 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 4000, while the ball mills ...
Mar 25, 2019 SAG mills. Replacements are seldom done to SAG mills due to cost and also the constraints of other circuit equipment. Instead, often additional production lines are added. Also, if the bottleneck is the SAG mill, adding a pebble crusher can provide a small production boost (typically 5 to 10%). Ball mills. For ball mills, replacement is less common. Often, after optimizing ball charge, liners
Tumbling mills are described using 2 indices M ia and M ib Crushers have one index M ic HPGRs have one index M ih For tumbling mills the 2 indices relate to coarse and fine ore properties plus an efficiency factor which represents the influence of a pebble crusher in AG/SAG mill circuits.
SAG mill can be applied as the first stage grinding equipment. It can effectively avoid the occurrence of sliming phenomenon, and avoid further grinding of fine particles. It can play a good role in controlling granularity and energy saving. Infrastructure investment and equipment cost is lower than common process The unit grinding cost of ore ...
A secondary crusher installed in 2014 allowed reduction of SAG feed size from 150 mm to 24 mm, thus enabling a significant shift in the milling circuit unit energy demand. With the feed size reduction, the circuit could process 1,850 mt/h, with a lower sensitivity to hardness variations throughout the orebody.
The pebble crusher product is fed back to the SAG mill. The grinding circuit has a cluster of 14, 500 mm Cavex Cyclones (130 mm polyurethane vortex, 102 mm ceramic spigot). Eight of these cyclones are used at any one time. The cyclone feed rate is 1,600 m3/h to 2,000 m3/h and the feed densities are nominally 60%. The cyclone overflow is fed to a ball mill (rubber lined Marcy ball mill, 5.03 x 8.50, 3.8 MW, fixed

20 EGL SAG mill, a Raptor 900 pebble crusher and two 24 x 396 ball mills. Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From startup, the mill struggled to meet the required production rates. Over time, a
May 25, 2021 Polyus says the mill is running at annualised capacity of 3.5Mt following the upgrade of the crushing and grinding circuit that included installation of an additional crushing circuit of a ball mill and two vibrating screens, an additional cone crusher and screens to reduce recirculation and increase the SAG mill capacity.
Jun 02, 2017 Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
Single-stage SAG mill models changed, removed open circuit SAG and replaced with two closed circuit SAG options, one with other without pebble crushing. Mill model detail pages now include an extra line of model detail showing values for key model sub-components. 2020
Oct 12, 2017 1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.

In Figure 7.35 shows the SAG mill closed with a crusher (recycle or pebble crusher). In SAG mill operation, the grinding rate passes through a minimum at a critical size ( Chapter 5 ), which represents material too large to be broken by the steel grinding media, but has a low self-breakage rate.
