Rushton turbine

The Rushton turbine or Rushton disc turbine is a radial flow impeller used for many mixing applications (commonly for gas dispersion applications) in process engineering and was invented by John Henry Rushton.

[1] The design is based on a flat horizontal disk, with flat, vertically-mounted blades.

[2] Recent innovations include the use of concave or semi-circular blades.
