Autogenous grinding or semiautogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally.
Autogenous Grinding Explained. Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5½'' diameter mill had both pebble ports and ½" wide slotted grates. The plus ½" mill product was crushed in a cone crusher and returned to the mill feed along with the minus ½" plus 4 or 6 mesh fraction.
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. The grinding is facilitated in autogenous mills by attrition ...

circuit or the overall performance of an autogenoussemiautogenous (AGSAG)/ball mill circuit, but they are of limited value in evaluating AGSAG and ball mill sections separately. This problem arises due to the difficulty of describing particle size distributions with different shapes by one number, the eighty percent passing size. This

Jul 30, 2012· Autogenous (AG) and SemiAutogenous (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 to 1. AG mills employ ore as the grinding media.
The two main character of an Autogenous Mill size reduction which occurs through the detachment of material from the surface of larger particles (referred to as ''abrasion'') and the grinding ...
Since the days of mandatory high cost pilot plant testing in 6 ft × 2 ft SAG mills autogenous griding/semiautogenous grinding (AG/SAG), mill speci c energy is now calculated by various fi empirical formulae and pilot testing carried out in small laboratory mills. Barratt (1989) described

Early research pointed to an optimum feed of 40% minus 3inch, 20% 3 to 6inch and 40% 6 to 10inch ... modeling of grinding circuits. Overall blast/mill ...
We offer autogenous (AG), semiautogenous (SAG), ball, rod, and pebble mills in sizes ranging from kWs up to 30+ MW. Our product range also includes a number of unique solutions, including the world''s largest acidresistant grinding mills, which can operate with extremely corrosive slurry.
Mar 16, 2016· Question what is an Autogenous mill? 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 assist...
In this case, Xinhai efficient autogenous mill solved these problems effectively. Xinhai efficient autogenous mill can achieve two and three stage crushing, part or all crushing of ball mill and rod mill, it is suitable for the coarse grinding after coarse crushing.
autogenous (SAG) mills were first used on ores in the 1950s, but they were not seriously considered by the mining industry until the 1960s. By the 1970s, most designers of new plants considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the grinding plants that were built used FAG
Is the Autogenous Mill a Cornish invention? The highest throughput grinding circuits in the mining industry use autogenous grinding (AG) or semiautogenous grinding (SAG) mills. An AG mill is a tumbling mill that uses the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media and preferably be ...
Ores which are comprised of sufficient competent pieces are amenable to AG mills. For such ores, AG mills perform crushing, fine and coarse grinding steps of size reduction. On the other hand, semiautogenous grinding (SAG) mills use steel balls as an additional grinding media.
Nov 26, 2019· AG/SAG is short for autogenous mill and semiautogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media, through the mutual impact and grinding action to gradually reduce the material size.
