SAG POWER INDEX (SPI®) TEST This test includes the SAG Power Index (SPI®) and Crusher Index measurements. The SPI® is a measure of the hardness of the iron ore from the perspective of semi-autogenous milling. The CEET Crusher Index (Ci) is used to predict the SAG feed size distribution of the ore, and is measured during the SPI®
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 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
belts to suppress dust in the plant, but this usage represents only a small fraction of the plant's total water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from
Causes Of High Mill Weight In The Sag Mill. Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder.A typical processing line at a mine might consist of a crusher followed by a sag mill followed by a ball mill.In this context, the sag mill and ball mill.
