Particle segregation in hydrocyclones | SpringerLink

1996-8-1 · Hydrocyclones and other dynamic separators are normally fed with pulps consisting of water and solid particles. The solids usually consist of particles of different sizes, shapes and densities. Except in the special case of monocharacteristic particles, the particles are segregated by these differences in size, shape and density. Segregation is magnified by the high values of centrifugal ...

2003-6-1 · Fractionation of kraft wood pulp fibres was carried out in a hydrocyclone. Long fibres tend to migrate to the low shear region and report to the overflow stream. Excellent fractionation was found at high pulp slurry feed rates with a split ratio between 0.07 and 0.3. However, when air bubbles are sparged, all the fibres are more uniformly distributed inside the hydrocyclone. When increasingly ...

The hydrocyclone is a dominant versatile classifier in mineral processing plants with a simple design that separates particles based on size, density, and shape. The separation is achieved by the dual-vortex flow behaviour set up by the tangential injection of a feed slurry through the inlet and the design of the vortex finder and spigot orifices.
