INTRODUCTION. Pilot-scale testwork based on a 6' x 2' mill is arguably still the. most reliable method for predicting full scale autogenous (AG) and semi-autogenous (SAG) grinding mill behaviour when treating. a given ore. However, the cost of a detailed pilot-mill programme. both in terms of providing sufficient sample material as well as the.

The idea and intention of applying this technology to SAG mills is not new. There have, no doubt, been many conversations which lamented the fact that the mysteries inside a SAG mill could not be directly observed via a camera, given the limiting assumption that such a camera could not survive the environment while providing a live video feed.

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by …

hemisphere. It employs the world's largest SAG mill, 40 ft diameter and two 22 ft ball mills in the grinding circuit. In that project, the owners considered it necessary to assess the dynamic response of the foundations for the SAG and ball mills due to vibration problems experienced in other installations. Numerical models of the foundations

The findings from emptying out and sizing 62 tons of charge, from a 4.7 m by 3.5 m diameter South African style SAG mill, into four axial segments are presented.

By this summer, a grinding mill that is bigger around than a Boeing 747 will turn chunks of copper ore into gravel-sized bits for smelting and refining. The largest ring gear ...

The SAG mill product flows to two 3.6 m (12′) by 7.3 m (24′) horizontal screens, whose combined oversize (pebbles) is diverted to two MP 800 cone crushers. ...

* SAG mills are the machines with the highest reduction rate which performs crushing, grinding and washing together. It offers a much higher reduction ratio than 3-stage crushing and screening system. * Feeding material in the dimension of 200-300 mm, is reduced to d100: 2 mm and below. This capability increases the efficiency of the ball mill ...

reliable drive system for SAG mills. Early SAG mills had a diameter of about 32', later increasing to 34, 36, 38 and 40'. At the same time the mill volume also increased. Typically a SAG mill has a much larger diameter compared to its length. Yet the SAG mill of Newmont's Yanacocha mine in Peru is a single stage mill (no ball mill after ...

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.

This paper expands the SAG mill survey database published by the Author at Procemin 2013. The new database includes 49 published SAG/AG mill surveys and includes mills from all over the world. The ...

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 mill's ...

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

24/05/2008 · First of all if you use CRS it will twist and crawl right off the table so you don't have to worry about sag. Bridgeports have a lot of sag when they come from …

7.0 m length (190) single SAG mill equipped with a 20 MW electric motor. The SAG mill product flows to two 3.6 m (120) by 7.3 m (240) horizontal screens, whose combined oversize (pebbles) is diverted to two MP 800 cone crushers. The crushed product returns to the SAG mill feed, closing the primary grinding circuit. The horizontal …

2. Background. The SAG grinding process has been modeled by various authors, either generating explanatory models of the grinding process, with the aim of modeling, simulating, and optimizing the individual process, as well as integrating it into aggregate processes, such as the mine-to-mill (M2M) paradigm, a practice that has …

The SAG mill power does not increase with an increase in the mill speed ratio, but when the speed reaches about 85% of the critical mill speed, the power decreases and the mill power increases ...
