Understanding particle hydrodynamics is crucial when designing and optimizing a cyclone system. Particle flow is more than the centrifugal force on the cyclone's wall, and deviations in this simple concept are at the root of the cyclone's issues and limitations. In an earlier PBE column, we discussed cyclone design and operation, 2 with an ...

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.

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.
