HYDROCYCLONE AND METHOD FOR LIQUID-SOLID SEPARATION AND CLASSIFICATION

摘要

Hydrocyclone and method for separating and classifying solids in which a slurry is introduced into the cylindrical inlet section (31) of the separati on chamber of the hydrocyclone so that the slurry rotates about the axis of the chamber, then passed through a first conically tapered section (22) of the separation chamber, and thereafter through a second conically tapered sectio n (23) which has a smaller cone angle than the first conically tapered section . The finer solids are removed through an overflow outlet (32) toward the uppe r end of the separation chamber, and the coarser solids are removed through an underflow outlet (28) toward the lower end of the chamber.
