The efficient autogenous mill uses the crushed material in the barrel body as the grinding medium, which continuously impacts and grinding to achieve the purpose of grinding. Sometimes, in order to improve the processing capacity of the autogenous mill, a small number of steel balls can be appropriately added, usually accounting for 2-3% of the ...
throughput of autogenous grinding/semi-autogenous (AG/SAG) grinding mills, but also contributes other process benefits such as improved wear life and operator-friendly steady and smooth mill operation. Following its introduction in 2006, Outotec's patented Turbo Pulp Lifter (TPL™) design has been retrofitted at existing sites and also
Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...
The grinding media of autogenous mills derive from the feed ore size and composition (Delboni and Morrell, 1996) and the varying ratio of different components in the mill feed affects the mill charge and consequently the whole breakage process. after developing a new AG/SAG mill model that describes the influence of mill charge composition on ...
Intermediate autogenous grinding can efficiently replace the rod mill and ball mill stage of a conventional grinding circuit. The need was shown for closed …
Autogenous (AG) and semi-autogenous (SAG) mills have been used for over 20 years for the coarse grinding of diverse ores (including gold, copper and iron ores). They offer advantages with regard to capital costs and operating expense compared to the secondary and tertiary crushers used in conventional size-reduction systems.
Description: Designed for autogenous or semi-autogenous grinding, the 6′ X 2′ continuous feed Autogenous or Semi-Autogenous Mill may be used as a pilot plant to determine the size for larger mills or for small scale milling projects. …
Autogenous mills, or AG 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, AG mills reduce the material directly to the desired final size or prepare it …
AG mill (autogenous mill) is a medium-free mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for self-grinding. The ore larger than 100mm in the AG mill plays the role of grinding medium.

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
An Autogenous (AG) Mill is a t umbling mill which utilizes t he ore itself as grinding media. For some ores, an auto genous mill combines t he size red …
The sights and sounds of large grinding mills in operation are impressive to even the most seasoned mill operator. Grinding systems are a symbol of the application of brute force to extract mineral wealth from nature and are a major and critical part of any mineral processing facility. Autogenous (AG) grinding is the size reduction of material ...
Five 40-foot AG (autogenous grinding) mills will be used for grinding the ore. For the ore mills, Siemens is supplying the gearless drives, …
AUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT ENERGY CONSUMPTION ABSTRACT The through-put and energy efficiency of an autogenous (AG) grinding mill are adversely affected by variability in rock size and rock competency. This applies to both fully autogenous and semi-autogenous (SAG) grinding circuits.
AG Mills&SAG Mills:φ2.4x1.2～φ13x4.0m,Effective volume 5.6～216m3； Since the early 1990s CITICIC has been designing and manufacturing both semi-autogenous (SAG) and autogenous (AG) grinding mills under the CITIC brand.CITIC HMC manufacture a full range of Grinding Mills for the Mining Sector.

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing …
The mill charge volume has a great impact on grinding efficiency. For efficient grinding, autogenous (AG) and semi-autogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.
generated. However in sag mills and in partcular ag mills the grinding media derive from the feed ore. The feed ore hardness and size distribution therefore dictate the number and size distri- bution of the grinding media which will vary greatly from mill to mill and ore type to ore type. It is this factor which has remained cen-
Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media. Our ball mills are the most robust design in the industry, available with either geared or gearless drive arrangements. The cost-effective …
Simplifying wet grinding with AG/SAG mills. AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.
For autogenous mills, like the dry Aerofall mills, MacPherson and Turner established that the power consumption was a function of mill diameter and length. For dry commercial AG mills they derived the power as (9.8) P M = 0.992 L D 2.8 ρ c where ρ c = bulk density of the mill charge (rock plus balls and water) (t/m 3) L, D are in metres and P ...
