Autogenous and SemiAutogenous Mills |

Rely on our proven track record of SAG and AG Mill superiority Since the early 1980s, we have been designing and manufacturing SemiAutogenous (SAG) and Autogenous (AG) Grinding Mills under the FullerTraylor brand Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenousSemiautogenous minevik 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 stagesSAG mills minevik Outotec

Some dry autogenous mills operating in Canada are 85 m in diameter and 15 m in length These are known as Aerofall mills The Cadia Hill (Australia) wet SAG mill is 122 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the worldthroughput of autogenous grinding/semiautogenous (AG/SAG) grinding mills, but also contributes other process benefits such as improved wear life and operatorfriendly steady and smooth mill operation Following its introduction in 2006, Outotec’s patented Turbo Pulp Lifter (TPL™) design has been retrofitted at existing sites and alsoImproving Autogenous/SemiAutogenous Grinding

Semi Autogenous Grinding Mill an overview

Size reduction occurs through a primary crusher followed by semiautogenous grinding (SAG) Large rocks are screened from the overflow and are sent through a pebble crusher, which recirculates the ore back to the SAG mill The smaller material after SAG milling is classified by hydrocycloningMill Sizing: After laboratory and pilot plant testing confirm the feasibility of autogenous or semiautogenous grinding, it can be used to establish the exact grinding circuit and mill sizeIn the pilot plant tests, the tare power of the pilot plant mills should be determined before and after each test run The tare power should be for the empty millAG Autogenous & SAG SemiAutogenous Mill

Semiautogenous mill power prediction by a hybrid neural

There are few methods of semiautogenous (SAG) mill power prediction in the fullscale without using long experiments In this work, the effects of different operating parameters such as feed moisture, mass flowrate, mill load cell mass, SAG mill solid percentage, inlet and outlet water to the SAG mill and work index are studied A total number of 185 fullscale SAG mill works are utilized toAG/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 sizeWhat's the Difference Between SAG Mill and Ball Mill

Semiautogenous mill power model development

Mill powers of the semiautogenous mill have an effective influence on the mill performance In this regard, a new predictive model based on gene expression programming (GEP) was developed to predict the mill power of the SAG mill To achieve this purpose, a total number of 186 fullscale SAG mill works were investigated and the most effectivethroughput of autogenous grinding/semiautogenous (AG/SAG) grinding mills, but also contributes other process benefits such as improved wear life and operatorfriendly steady and smooth mill operation Following its introduction in 2006, Outotec’s patented Turbo Pulp Lifter (TPL™) design has been retrofitted at existing sites and alsoImproving Autogenous/SemiAutogenous Grinding
