The 6 Diameter X 2 Long Continuous Feed Autogenous/SemiAutogenous Mill With Base amp; Stand Description: Designed for autogenous or semiautogenous grinding, the 6 X 2 continuous feed Autogenous or SemiAutogenous Mill may be used as a pilot plant to determine the size for larger mills or for small scale milling projects.
The difference is that the barrel body of efficient autogenous mill is larger, which does not use steel ball or any other grinding medium. 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.
The Autogenous/Semiautogenous Grinding Mills are in most cases used as primary crushers. AG Crushers use the ore exclusively as their grinding media. In case the hardness and the abrasiveness of the Ore is not suitable enough to carry out the grinding process, steel balls are added inorder to assist the process; these are called SAG Crusher.
The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).
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 for the following grinding stages.
supported grinding mills up to the largest sizes. SAG/ball mill circuit incorporating pebble crushers and a POLYCOM#174; highpressure grinding roll. SAG and ball mill for gold ore grinding. One of three SAG mills with m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.
SAG mills (semiautogenous grinding mills) Semiautogenous mills or 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

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.
The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media; the rock itself In conventional milling, the ore is crushed to, plus or minus, 3/8 of an inch, before it is put into a mill for grinding. In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself. The size of
#0183;#32;Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media. Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills.
Autogenous grinding, strong selective crushing effect, less over crushing, easy to screen, which is beneficial to improve mineral processing index and increase the concentrate grade and recovery.
Worldwide manufacturer''s representative of standard amp; custom grinding amp; mineral grinding mills. Mills such as ball mills amp; semiautogenous grinding (SAG) mills are available. Onsite field winding amp; installation services are available. Meets ASTM, ASME, API amp; AWWA standards.
Semi autogenous grinding mill used in mineral processing pilot plant testing for primary autogenous or semiautogenous grinding gives the following information needed for selection of mills, circuit design, and mill design, and since the ore determines the nature of the product from an autogenous or semiautogenous grinding circuit
High Impact Grinding Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semiautogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process.
