Standard Designs of Industrial Cyclones
Standard configurations of industrial cyclones for particulate collection/removal
are available resulting from a compilation of many empirical measurements.
Cyclones for other applications (e.g. industrial hygiene or pharmaceutical)
are usually custom designed, but they are based on the same principles.
The table below lists some of the standard designs. Generally they are
grouped into 3 classes: high efficiency, medium efficiency and general
purpose. All dimensions listed (e.g. inlet height) are normalized
to the cyclone's body diameter.
