Abstract
A classification system utilizing a cone which is rotated at a specified speed is provided. A stream including a solvent is introduced into the classification, and the stream impacts against the cone and flows along the inside face of the cone. The side of the cone is sufficiently long that the conic face filters the introduced flow, thereby removing substantial portions of the solvent and leaving the heavier or classified parts. The discharge from the cone is thus segregated liquids and solids, and the solid stream is a flow of classified particles and a portion of the solvent. The solvent portion is sufficient in volume to conduct the classified particles as a heavy or thick slurry out of the system. There is an interplay between the length of the cone, i.e. the length along which the introduced slurry must flow, also, the cone angle, and the pores through the cone wall.
