Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine …

It can pick up gold associated with other minerals, such as sulphides but generally, it is most efficient at targeting free gold due to the high density difference." As the name suggest the Continuous Knelson is designed to be run in continuous mode and doesn't need to be installed in a circulating load to maximize recovery efficiency.

The presence of a sizable quantity of pebbles in the pulp lifter limits the space available and reduces the flow gradient through the grate thus increases the load inside the mill and hence the mill power-draw. This paper analyses all the problems associated in discharge of slurry and pebbles in SAG mills with pebble circuits.
