The Rushton turbine is mainly used because of its extensive centrifugal effect for the dispersion of gas/liquid. This dispersion fosters the gas/liquid exchange for processes such as aerobic fermentation.
It can also be found in special applications such as stripping type processes.
It is often combined with one or more pumping propellers to stimulate the turbine during gaseous dispersion.
DESIGN OF THE RUSHTON TURBINE
Definition basis: Disk turbine with vertical blades
Number of blades: 6
Rotation direction: Clockwise or anticlockwise
FLOW OF RUSHTON STIRRING DEVICES - USE
Horizontal, radial, centrifugal flow.
Vortex creation by depression.
The stirrer equipped with a Rushton turbine can be mounted centred with counter-blades or offset without counter-blades.
Extensive shear effect at max. speed (medium peripheral speed ± 5 m per sec)
