ABSTRACT:
Hydrocyclone and method for separating and classifying solids in which a slurry is introduced into the cylindrical inlet section of the separation chamber of the hydrocyclone so that the slurry rotates about the axis of the chamber, then passes through a first conically tapered section of the separation chamber, and thereafter through a second conically tapered section which has a smaller cone angle than the first conically tapered section. The finer solids are removed through an overflow outlet toward the upper end of the separation chamber, and the coarser solids are removed through an underflow outlet toward the lower end of the chamber.
