Chat01/01/2016· Mills that grind hard ores with fracture characteristics that do not lend themselves to fully autogenous milling are charged with a small amount of steel balls to assist in the size reduction. These are known as semi autogenous grinding (SAG) mills. In the mining industry all of these types of mills are in use.

ChatAUTOGENOUS MILLS AND SEMI AUTOGENOUS MILLS. In the process of autogenous grinding, the material itself is used as a grinding body. In the course of semi autogenous grinding, auxiliary grinding media (usually steel balls) are used. 's MSI/MPSI mills are ideal for grinding ore or primary crusher products. This line of mills includes models of various sizes

ChatAutogenous 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

The model relates charge motion and composition to power draw and size reduction. Size reduction is described by considering impact and attrition/abrasion as separate

Chat12/10/2017· 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.

ChatAdvanced Simulation for Semi Autogenous Mill S ystems: A Simplified Models Approach 147 description it is necessary to consider the relationship between the feed stream and mill charge level. This relationship is known as the transport rate and is probably the least developed aspect in models proposed so far (Apelt et al., 2002 a,b). 2.2 Transport and water balance The

ChatAutogenous grinding mill: in this grinding mill, rotating drums throws in large balls of matter in a rapid motion. This causes the ball to break and make smaller particles. SAG mill: SAG is the short form of semi autogenous grinding. The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill. SAG mills have built in lifting plates inside the

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusherfor mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with di

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. These heavy output SAG mills are usually

ChatAutogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is normally two to three times the length. It can, therefore, be concluded that autogenous grinding was not suitable with this particular gold ore, but semi autogenous operation with about 8% ball charge was the preferred option. Based on these test results, a m diameter × m length SAG

Chat20/07/2017· In autogenous grinding, one way to change the product size is to switch to semi autogenous grinding which will give a coarser product than autogenous grinding and usually at less power consumption per ton. The Cleveland Cliffs Iron Company referred to this in their paper on autogenous grinding.

ChatConcentrators vary similarly. A new large concentrator unit typically consists of a semi autogenous grinding mill, high pressure grinding rolls, two ball mills, and a flotation circuit. It can treat up to 170 000 tonnes of ore per day (Sartain, 2010). Larger concentrators consist of multiples of this basic concentrating unit. Smelters are almost always large because their

SAG mills have built in lifting plates inside the

ChatThe semi autogenous mill is also called SAG mill which is an acronym for semi autogenous grinding. It is similar to an autogenous mill but uses grinding media like a ball mill grinder. It takes material itself as the main grinding media and grinds through their mutual collision. However, some raw materials with a diameter greater than 20mm and less than 80mm are

ChatSAG is an acronym for semi autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42 (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44 (13.4m) diameter and a power of 35
