Gravity Separation - an overview | ScienceDirect Topics

Centrifugal separation can be regarded as an extension of gravity separation, as the settling rates of particles are increased under the influence of centrifugal force. It can, however, be used to separate emulsions which are normally stable in a gravity field. Centrifugal separation can be performed either by hydrocyclones or centrifuges.
