Definitions

  • the length of the hub sleeve in the direction of the axis of rotation is greater than the length of the rim of the wheel disc.
  • the length of the hub sleeve in the direction of the axis of rotation is at least 30%, better at least 50% greater than the corresponding length of the rim.
  • a certain proportion of classifier air is additionally blown into the classifier space via the coarse material outlet 8 or the auxiliary air supply 9 arranged there, by means of a blower (not shown in the figure).
  • This auxiliary air supply is in Figure 1 symbolized by the small black arrow. This means that particularly fine material that has unintentionally fallen into the area of the coarse material outlet or unintentionally falls into this area threatened to fall, transported back into the sifting room. This leads to a significant improvement in the quality of the screening results.
  • the classifier wheel 7 essentially consists of a classifier drum 14 with a classifier wheel shaft 11, which forms its axis of rotation.
  • the rim is preferably provided on its outer peripheral surface with one or more sealing grooves 23, which form part of the labyrinth-like seal with which the classifier wheel is sealed on its end faces from the fine material outlet 6 - which will be discussed in more detail later.
  • the preferred design of the spokes 17 can be seen from the rear part of the Figure 6 comprehend.
  • the spokes 17 preferably extend in a purely radial direction from the hub sleeve 16 to the rim rim 18.
  • Each spoke 17 is just as long as the latter where it is connected to the hub sleeve 16, measured in the direction of the rotation axis L.
  • Each spoke 17 tapers towards the rim 18. This means that each of the spokes usually protrudes into the interior of the sifter drum 14 and protrudes outwards on its opposite side in the direction of the axis of rotation L over the rim rim 18. In this way, the spokes have a relatively large area and can therefore effectively help to get the classifier air to rotate.
