Definitions

  • the invention relates to a rod cage sifter for sifting granular material to be separated, having at least one motor-driven rod cage, a housing for the rod cage, the housing having at least one inlet opening for an air flow with suspended material therein, which is arranged in such a way that the air flow from on the outside of the rod cage, and at least one outlet opening for an air flow with fines suspended therein, which is arranged at a first axial end outside the axial length of the rod cage and within the diameter of the rod cage, and at least one outlet opening for coarse material, which is arranged at a second axial end outside the axial length of the rod basket and outside the diameter of the rod basket.
  • the object of the invention is to provide a rod basket classifier that at least partially compensates for its own flow resistance.
  • an impeller on the rotating rod basket with the help of which air or a conveying gas can be compressed from a process plant.
  • This compressed air or this compressed conveying gas can be added to the inflowing conveying air with the conveyed material suspended therein, or it can be fed into an air flow or material flow emerging from the basket classifier rod.
  • the impeller is separated from the rest of the rod cage by a partition wall. This enables a gas separation or a separation of different material streams.
  • the impeller is in flow connection on its inside with an inner air duct and is in flow connection on its outside with the outlet opening for coarse material.
  • This gas routing from the inside to the outside makes it possible to feed the compressed gas into the separation space immediately outside the rod cage, so that the conveying air or the conveying gas for the sifted material and also the conveying air or the conveying gas for the coarse material are mixed with the compressed conveying air or the compressed Conveying gas are applied.
