A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing. The Sag mill is usually part of the primary stage in the grinding process. Pieces of raw or fairly reduced materials are ground into smaller pieces for further processing or sorting.

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

SAG Mill Power. SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly non-linear and shift as the ore hardness, steel load and liner conditions change.

Sag mill gets like 1.5-2x the output of a pulverizer with dark steel balls. So I use sag mills for processing my ores. I think an IC2 furnace is the fastest furnace available? But regardless, I just use an alloy furnace since it's far from slow, and it fits the style of the sag mill. Plus, I don't like IC2.

Multotec, a South-Africa based supplier of mineral processing equipment, recently highlighted the capabilities of its SAG mill trommel screen line, describing it as a viable alternative to vibrating screens in SAG mill scalping applications, with features that offer high throughput and extended wear life.

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of …

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%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44 ...

SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material ...

Autogenous and Semi-Autogenous Mills Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media.

Outotec presents the world's largest SAG mill. Outotec has recently been awarded a contract to deliver one of the largest grinding mills in the world.

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...

The mill's continuous operation is interrupted when the mill liner — which comprises riser bar plates that protect the original casing and provide required lift required for grinding action — wears out after months of processing abrasive material. Overall, SAG mills are expensive to operate due to several factors, including high power ...

Abstract In the existing JKMRC breakage testing method for AG/SAG mill modelling, ore is characterised using mainly high energy single impact tests. However, recent DEM studies have suggested that breakage in AG/SAG mills is mainly due to low energy repetitive (or multiple) collisions rather than single high energy impacts. Furthermore, several of the published AG/SAG ore hardness tests ...

The SAG mills are generally used in pre-processing of any type of material in grinding process. SAG mills are also known as first stage grinders. These heavy output SAG mills are usually powered by electricity. As requirements and needs in grinding field are enhanced. Improved SAG mills came in trend, which gives highly rated production.

The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product.. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.

Interesting, as in a recent article in Mining Magazine (July/August 2014, pp. 27), Kurt O'Bryan of Weir Minerals says that, although SAG mills have been around for over 40 years, the demand to process more ore in less time is a key factor in where comminution trends are heading. He says that "SAG mills have to be bigger to meet these demands.

The one sound operators do not want to hear is the sound of the mills standing still. A gold-processing plant, I visited recently valued their SAG mill downtime at US$ 130,000 per hour, so extending the life and availability of mill liners is crucial to them. The reduced damage improves the mills' availability and minimises the downtime.
