The cutpoint size, a measure of a cyclone's performance, is defined as the particle size for which half the particles exit at the top and half at the bottom. A coarser (larger) cutpoint means that only larger particles can be separated. A finer (smaller) cutpoint means that smaller particles can be removed.

Phenomenological Study On Fine Particle Misplacement

Nov 10, 2016 The flow field inside a hydrocyclone is essentially a swirling flow, generated by tangentially introduced velocity. Specifically the radial distribution of the tangential velocity, at any cross section, suggests a Rankine vortex flow profile [1, 10, 12].The unsteady nature of particle separation in a vortex flow depends on the length scale of the sediment particles and also the characteristic ...

Sep 15, 2010 Dilute flow separation in a hydrocyclone (φ P ≲ 7.5%): a) radial concentration profiles of narrow particle size classes; b) dilute flow separation; c) shape of the separation curve. Obviously the highly turbulent character of the hydrocyclone flow is the reason for the shape of the separation function ( Re number in the range 10 5 to 10 6 ).

Factors Affecting The Classification Efficiency Of

May 19, 2021 In general, the height of the hydrocyclone column is 0.6-1.0 times the diameter. The higher the height of the column, the finer the separation particle size, but if it exceeds a certain limit, it will lose its effect due to the increase in the pressure loss of the mine. B.

A hydrocyclone separator is a piece of equipment used to classify particles according to their size and density. Hydrocyclones have no moving parts; instead they are shaped like a cone to produce a vortex when slurry is fed into the cyclone. In generating sufficient centrifugal force, this vortex allows coarser and finer particles to separate.
