Rushton (RT) Radial Flow Disk Blade Turbine
High-intensity mixing where medium duty gas dispersion is required. Works well in processes requiring simultaneous solids suspension. Designed to handle low to medium viscosities.
The original disc blade turbine invented in the 1950’s, the standard Rushton Turbine model features 6 flat vertical blades, however, 4 and 8 blade options are common, depending on the application. In low to medium duty gas dispersion applications, the Rushton power input will drop due to the gas presence up to 60% requiring a variable frequency drive, or two-speed motor.
The Rushton Turbine should not be utilized for solid-liquid mixing applications, as radial flow turbines do not suspend solids for the least power input. However, in three-phase reactors with both a high gassing duty and solids suspension requirement, the gas dispersion demand is more critical to process success and a Rushton Turbine must be used. In this case, the process success dictates the agitator design and the power input does not factor when deciding on the optimum impeller-mixer configuration.
