Abstract
A centrifugal separator having a bowl and means to rotate the bowl about a longitudinal axis, the bowl including a cylindrical section and a coextensive conical section whereby, in use, a bath of feed material will form partially up the conical section as the bowl rotates with the remainder of the conical section forming a beach area up which separated solids are conveyed by a screw conveyor adapted to collect separated solids from adjacent the inside wall of the bowl and convey them out of the bath and up the beach to an outlet from the bowl, with weir means in the form of an overflow passage to allow substantially solid free liquid to be removed from the bowl, a first conduit extending into the bowl through one end thereof and coincident with the rotation axis thereof, and one, or more second conduits within and coaxial with respect to the first conduit and each other to define an inner passage and at least one outer annular passage through which feed material, and at least one separate treatment material may be delivered into the bowl.
