Typically this type of mill can deliver a product with a fineness of less than 0.1 mm. Testing of material is needed before hand to determine the suitability of the ore for processing in an autogenous mill. The rod mill (Fig 1) is a tumbling mill which is having a large percentage of its volume (30 % to 40 %) loaded with steel rods.

The so-called semi autogenous mill is formed by adding an appropriate amount of steel balls into the autogenous mill. According to the shell shape and ore discharge method: the ball mill is ...

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.

SAG mill. SAG stands for Semi-Autogenous Grinding. Just like ball mills, these machines also have grinding balls in them. Actually, a SAG mill is used as a primary stage solution for grinding. It comes with a 28 MW motor and a diameter of 44 inches. As a matter of fact these machines are used at platinum, copper and gold mines.

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.

nano mill core parts . Autogenous grinding uses big fragments of material as the media, hence it is milling by attrition (self-grinding) rather than impact. A cascading motion is created by a rotating drum, which induces breakdown into finer particles.

Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.

What's the Difference Between Ball Mill, Rod Mill and SAG Mill? There are several classification methods for grinding machines. Among them, the more commonly used one is to divide them according to different grinding media: whose media is metal balls is called the ball mill, steel rods the rod mill and the ore itself the autogenous mill (AG mill).

The autogenous mill (AG) or semi-autogenous mill (SAG) for grinding particulate can have a feed inlet for flowing feed particulate into the mill. The feed particulate is also known as "the charge" in the mining and milling industries.

The autogenous welding limits the wall thickness to approximately .16 in. or 4 mm. ... 316L, VIM/VAR, ultra low manganese, electropolished to a 5Ra max., hydrogen bright annealed OD with electrically etched mill markings when all you thought you needed was stainless steel. The following considerations are some of the most important for selecting a

Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore. Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media.

Other articles where autogenous mill is discussed: mineral processing: Grinding: Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.

SAG is the abbreviated form for Semi-Autogenous Grinding Mill. This type of Mill is used for grinding large fragments into small pieces. Pieces are then used for further processing. 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.

The Solios Carbone contract consists of the engineering and supply of all equipment for the following: hot crushing of the crust shovels and anodes butts cleaning bath; cooling in a metallic pan conveyor; processing in an airswept autogenous mill designed by Fives Solios for storage of the product dedicated to the cover of the electrolysis pots.

Semi-autogenous Outotec SAG mills, as they are often called, 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 directly to the desired final size or prepare it for the following grinding stages.

Autogenous and Semi-autogenous (AG/SAG) grinding mill circuits are among the common grinding devices in comminution circuits. AG/SAG take advantage of ores whose

An autogenous AG mill is a grinding mill used in the minerals processing industry It is shaped like a huge drum on its side and spins rapidly to carry ore to the top using centrifugal force Gravity assists in smashing ore against other ore to pulverise rock to a size small enough to seperate minerals from gange.

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 ...

In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore. The main source of reduction comes from the impact of the rock falling on rock.

Semi-autogenous grinding mill. It is a rotating barrel in which ore is broken by ore pieces (0.2 m diameter) and steel balls (0.1–0.14 m diameter) falling on ore as they are lifted and fall off the moving circumference of the barrel. Autogenous grinding mills are similar but without the steel balls. The mills are fed and grind continuously.

It is called autogenous mill with its own ore as medium. The so-called semi autogenous mill is formed by adding an appropriate amount of steel balls into the autogenous mill. According to the shell shape and ore discharge method: the ball mill is divided into short tube, tube and cone overflow ore discharge and lattice ore discharge, the rod ...

In order to improve the quality of autogenous mills products and reduce grinding cost, semi autogenous grinding mill manufacturer invests great manpower, material resources, and financial resources. This paper will take Xinhai mining group as an example to introduce the advanced technology of semi autogenous grinding mill manufacturer.

Mill operators have long used operating work indices to evaluate grinding circuit ... circuit or the overall performance of an autogenous-semiautogenous (AG-SAG)/ball mill circuit, but they are of limited value in evaluating AG-SAG and ball mill sections separately. This problem arises due to the difficulty of

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...
