An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process. In this type of circuit, the ore must be competent so large chunks of ore can be used to grind smaller chunks of ore. https://

The designs of autogenous and semiautogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described.

A recent calculation on a 30′ diameter, 7000 Hp, semiautogenous mill indicated that a flat end vs. conical end construction would require a shell weighing 13% more to account for stress alone. Deflection was still better in the conicalended mill as opposed to the flatended mill. ... (as many autogenous mills do) it is vitally important ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Introduction The degree to which slurry is held up within autogenous (ag) and semiautogenous (sag) mills influences their grinding capacity and power draw. The roles of the grate and the pan lifters (in trunnion discharge mills) are particularly influential in this regard. Once a mill has been installed little can be done to affect the ...

In spite of the important advances in modelling and simulation of autogenous and semiautogenous grinding made in recent decades (NapierMunn et al., 1996, Morrell, 2004), risks exist in designing a circuit adopting AG/SAG mills for lowgrade itabirite iron ores from benchscale information.
