Chat Online### Modelling SAG milling power and specific energy

It is also possible to use the −1″ fraction that shows a positive effect on the SAG mill throughput (the power consumption decreases but the specific energy decreases more) because the mineral goes faster to the mill discharge leaving a greater part of the grinding task to the secondary ball mills.

Chat Online### Charge behaviour and power consumption in ball mills

The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.

Chat Online### Optimization of mill performance by using

Mill power Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration.
