Hydrocyclone Working Principle
The centrifugal force (the central Hydrocyclone Working Principle) that is generated by this spin, forces the "bigger particles outwards towards the wall of the cyclone. If you were able to do a cross section of a cyclone while it is operating, you could see that the ground rock will become finer the closer that you get to the centre of the ...
