a. A centrifugal device for dewatering, usually conical or bowl-shaped, in which the containing surface is imperforated. The greater density of the solid particles causes them to collect preferentially in contact with the inside of the containing surface where they are discharged mechanically; the water usually overflows from a position nearer to the axis. BS, 5
b. A rotating device for separating liquids of different specific gravities or for separating suspended colloidal particles, such as clay particles in an aqueous suspension, according to particle-size fractions, by centrifugal force. Colloidal particles that cannot be deposited from suspension by gravity can be deposited by centrifugal force in a supercentrifuge. See also: cyclone
