Semi-autogenous grindingis applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed byball millsorrod mill-ball millcombination.[email protected]
Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. Metso offers flexibleautogenous(AG)mills,semi-autogenous(SAG)mills,balland pebblemills, as well as stirredmillsto fit your needs.
Semi-autogenous millsorSAG 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 millsreduce the material directly to the desired final size or prepare it for the following grinding stages.

Semi-autogenous millsare more common. TheAG Millor SAG grinds primary crusher product and prepares it for final grinding in aball mill. Its product is usually passed over a large vibrating screen to separate oversize ‘pebbles’ from correct-size particles. Thecorrect-sizematerial is sent forward to aball millfor final grinding.
The designs ofautogenousandsemi-autogenous(SAG)grindings millsare described followed by the description of their methods of operation in grinding circuits involving crushers andball mills. Methods of estimatingSAG millvolumes,millcharges, feed size and power consumptions and optimum speeds of rotation during operation are described.

Semi-autogenous grindinguses a minimalball chargein the range of 6-15% whileautogenous grindinguses ore only. SAG and AGMillsoperate by lifting ore/grinding media and dropping it on the operating bed of themillcharge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in themill.

SAG is an acronym forSemi-AutogenousGrinding.SAG millsare essentiallyautogenous mills, but utilize grinding balls to aid in grinding like in aball mill. A SAGmillis generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles.
Autogenous mill, AgMill,Semi-autogenous Mill,Ball Mill... Sometimes, in order to improve the processing capacity of theautogenous mill, a small number of steel balls can be appropriately added, usually accounting for 2-3% of the effective volume of theautogenous mill(also known assemi-autogenous mill).
Semi-autogenous milluses the mineral and steelballas grinding medium for ore grinding.
