Cyclone Dust Collector Manufacturing and Fabrication by BCE

Centrifugal separators, or cyclones, are the most commonly used types of dust collection equipment.  They are simple to manufacture, inexpensive and have no mechanical or pneumatic components and, unlike conventional baghouses, can operate at temperatures over 1000°F.

Dust-laden air enters a cyclone tangentially.  As the main vortex spirals downward, the coarser particles move to the wall, due to inertia, and are discharged through the hopper.  An inner vortex forms in the cone and spirals upward and out of the cyclone, carrying finer particles with it.  Cyclones are often used to remove larger particles from the air stream ahead of a baghouse in order to reduce the dust loading.

The major drawback of a cyclone is its low efficiency for respirable particulates (< 5 microns), although efficiency increases markedly at high dust concentrations and for agglomerating dusts.  If the material is especially abrasive, the walls are subject to erosion, in which case abrasion-resistant construction, replaceable inlet scroll or a liner may be indicated.  It should not be used for sticky dusts.

BCE offers single and multiple types of cyclone dust collectors.  Multiple cyclone collectors include dual and quad as well as multiclones, which feature a large number of small cyclones operating in parallel with a common inlet and outlet.
