Two Types of Centrifuge Separation

In the usage of a centrifuge you have two designs based on general physic rules.  One design is based on filtration via spinning the feed material at a increased "G" force allowing the liquid phase to pass through a filter media leaving the dewatered solids on the filter media.  The other basic centrifuge design is via sedimentation.  In this separation design a feed slurry is accelerated to a increased "G" force allowing the solid phase to settle against the inside diameter of the rotating assembly.  Once the solids are settled they are removed by hand, port opening, a scroll or a blade typically.  The liquid generally overflows a level ring or weir plate to be discharged.
