Open Blade Turbine

  • In open blade turbine, the blades are directly mounted on the hub.  The number of blades may be two, four, six or eight.
  • Two-blade paddle is generally used for solid suspension or blending applications requiring high flow and low shear.
  • Paddles are normally operated at low speeds
  • Coil impellers were developed for applications where solids frequently settle at the bottom of the vessel
  • Spring design ensures that the impeller has adequate mechanical rigidity, strength to overcome the resistance offered by stiff solids during mixing operation
