The SPI® test itself requires 2kg of ore with a top size of 19mm (¾"), but a total of 10kg of 38.1mm (1-½") is generally preferred, which allows for the determination of a crusher index (the crusher index is used to estimate the size distribution of the primary crusher). The sample is prepared to have an F. 80.

AG/SAG Mill Liners Shapes. The shape of the AG/SAG mill liners include: Flat liner. For fine grinding silo, the rising height of the grinding body depends on the static friction coefficient between the lining plates. Bead liner. Used in the first bin, it can make the grinding body rise higher and have larger impact energy. Convex ribbed liner.

The point of the Coarse Ore Silo is to supply a flow capacity between the SAG mill and the existing crusher building. The Coarse Ore Silo is a cylinder made of concrete having a diameter of 64 feet and a height of 118 feet. The interior surface of the silo is lined with steel rail track. On top of the silo is a structural steel penthouse with about 38 feet long by 22 feet wide and 18 feet in

Ore grindingthis uses a single stage SAG mill operating in a closed circuit. This produces a 200 micron feed which is then directed to the leach tanks. The SAG mill operation is unusual in that sulphuric acid is added to the circuit to start the leach process early in advance of the leach tanks. Service Online

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your

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 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of
