Centrifugal Separation - Christian Brothers University

The separation factor of a cyclone is defined as the ratio of centrifugal to gravitational forces: In most cyclones the particles being separated are small enough that Stokes' Law can be used to determine the drag force. This means that the force balance on a particle under centrifugal force becomes

How to Improve Cyclone Separation

Cyclone performance is rated in terms of particle cut diameter or cut size. The cut size, dp50, is the particle size which is captured 50%. The relationship between particle cut diameters for this type separator, where dp is the particle diameter and the numerical subscript denotes the collection efficiency of that size particle.

designs applied, the separation efficiency seldom surpasses 60%. The end result is that most grinding circuits closed by hydro cyclones operate with high circulating loads that range between 230 – 450%. (See figures 3, 4, 5 and 6 for circuit types). The grinding operation in a mineral processing facility typically consumes the

(PDF) Cyclone Separation | Bryle Kristiann Camarote ...

However, theoretically, cyclone separation efficiencies should increase with increasing particle density. This is because an increase in the air-particle density difference results to higher resultant centrifugal force in the cyclone separator (Gawali & Bhambere, 2015).

Air Pollution Control Technology Fact Sheet

The collection efficiency of cyclones varies as a function of particle size and cyclone design. Cyclone efficiency generally increases with (1) particle size and/or density, (2) inlet duct velocity, (3) cyclone body length, (4) number of gas revolutions in the cyclone, (5 ) ratio of cyclone …

Design and Analysis of Cyclone Seperator

cyclone separator by varying its flow temperatures. Finally to study the performance of a cyclone separator with collector and compare to that without collector. Four geometrical factors have significant effects on the cyclone performance viz., the inlet width, the inlet height and the cyclone total height.

Cyclone Dust Collectors | Industrial Air Filtration, Inc ...

Cyclone dust collectors rely on centrifugal force to remove larger dust particulates from the air in industrial applications. This type of dust collector uses a mechanical separator, usually a helical baffle, and a tapering cylindrical shape to remove dust and dirt, which then drops into a collection hopper once the dust loses velocity.

Mineral processing - Wikipedia

Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores .


Although the aim of cyclone operation is to separate particles by size, particle density, particle shape and other factors also affect the settling rate of particles and hence cyclone performance. Cyclones are used in preference to screens as a means of size separation in the grinding circuit as they are more efficient at fine separation sizes.
