ABSTRACT
Centrifuging and cycloning are in principle very much like gravity settling, but with the force of gravity increased many times using centrifugal force. They can be used to separate solid and liquid particles from gases, immiscible liquids from each other, and solid particles from liquids. Thus, they find frequent use in applications where gravity settling would be considered but would take too long. Such applications involve either low density difference between phases to be separated, small particle size of the dispersed phase, or high viscosity of the continuous phase. The multiplication of gravity by centrifugal force makes these applications possible in a reasonable length of time.
