Air classifier

The RHEjet air classifier is ideal for classifying processes with high capacities and at the same time a very fine cut. 

The RHEjet air classifier combines the functional principles of a Sturtevant classifier and an Onoda classifier into a completely new classifier type. By means of CFD simulation of the expected particle flows, it was possible to achieve the design of a very high dust loading of up to 700 g/Nm3 and a pressure drop of only 9-12 mbar while achieving a sharp separation.

Advantages of the RHEjet air classifier

  • Perfect adaptability by adjustment of the volume flow, rotational speed, flap positions and feed rate
  • Dispersion of the solids before entering the classifying zone across several spreading discs optimizes the result
  • Ideal inflow to the impeller by deflector plates adjustable from the outside
  • Low pressure differences thanks to flow-optimized geometry ensures reduced operating costs due to lower energy consumption and low-wear operation
