the importance of grinding autogenous mill ME Mining

the importance of grinding autogenous mill. Autogenous grinding is gaining in popularity, as the grinding media costs are much less, and this process does not produce as much slime or fines as traditional rod and ball mills. Autogenous mills can handle both wet and dry operations. In some applications that require the grinding of minerals, such

AG Autogenous Grinding

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

Autogenous and Semi-Autogenous Mills ScienceDirect

Jan 01, 2016· 9.1. Introduction. Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. 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.

MacPherson Autogenous Grindability Test Mining SGS

The mill power draw, throughput and product size distribution are used to compute a specific energy input and the MacPherson autogenous work index (AWI). Although the importance to achieve steady-state in a grinding test is widely accepted (Bond tests), the MacPherson test remains the only small-scale AG/SAG mill test that offers this option.

The Modelling of Autogenous Grinding ScienceDirect

Sep 01, 1989· It is evident that mechanisms of grinding must be different or at least have different importance from both ball mills and from large diame- ter autogenous mills. Therefore some of the assumptions made for ball mill models are not appropriate and ball mill models cannot be used in mod- elling autogenous mills nor pebble mills.

The Importance of Evaluating Grinding Performance AusIMM

Description. Previous papers at Metplant conferences have covered the options for crushing and grinding circuit selection. High Pressure Grinding Rolls (HPGR) may have considerable advantages over autogenous milling circuits but test work and evaluating different grinding circuits must be done to establish which circuit provides the best option.

Semi-autogenous grinding (SAG) mill liner design and

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

Small-Scale Continuous SAG Testing Using the Macpherson

Fully-autogenous (FAG) and semi-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

Autogenous and Semiautogenous Grinding Practices

Picking the proper crushing and grinding method must, therefore, be done with great care, so the best circuit is chosen. In the past 10 years, there has been a strong trend toward using autogenous or semiautogenous grinding in mills throughout the world. Autogenous grinding is favored when the ore is quite competent and a fine grind is needed.
