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
Semi-autogenous plus ball mill has been the "work horse" of mills. SAG vs Ball Mill Advantages . AG & SAG Mill Grinding Compared – Which is Best. Grinding rods and balls can be obtained in uniform sizes, weights and of a specified quality. Their action in a mill can be reasonably predicted.
The cradles need to be lifted up to sit under the shell then jacks placed under the cradles. You sit the jacks on some big thick steel plate to dissipate the load a bit otherwise could punch through the concrete. You will insert the jacks between the cradle and the shell and then if you lift the cradle up off the concrete plinths the same gap.
SAG mills and AG mills have different definitions and operate differently. SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore.

Q1. What is a SAG mill used for? A SAG mill is used to grind and crush large pieces of rock into smaller pieces of rock, gravel, or dust. It is commonly used in the mining industry. Q2. How does a SAG mill work? A SAG mill uses a combination of impact and attrition to grind the material.
Rods are also generally more expensive than balls and harder to handle. This means a rod mill equal in capacity to a ball or SAG mill would take up more plant floor area requiring a larger building. ... SAG mills are used predominantly with feed material with a larger max lump sizes (from primary crushing plant typically in the max lump size ...
Bal And Sag Mills Cemtex - friendsoftheloews. Molino Sag Y Ball Mill Toromocho. Bal And Sag Mills Cemtex. SAG 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.
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product ...

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
Safety Notes; they result from internal stresses in the balls impact and heat energy in the SAG mill causing a Martensite transformation in the ball (Crystals form in the metal) and they have a potential to rupture with very sharp edges.
