  • FIG. 8 shows a side view of the deck 4, the core tube 11 of the first rotary element 7 having a different outside diameter than the core tube 11 of the last rotary element 10 and the further rotary element 5 arranged below the last and penultimate rotary element 10, 9 ,
  • the rotation elements 3 are arranged at a distance from each other, as can be seen in particular with reference to the detail views of FIG.
  • the spacing of the rotary elements 3 to each other results between immediately adjacent rotary elements 3 each have a gap 6.
  • the pure distance 17 between adjacent core tubes 1 1 of the rotary elements 3 ultimately corresponds to the web height 16 of a coil 12 plus a few millimeters. An arrangement without spacing would lead to high wear and possible damage to the device 1.
  • a corresponding spacing is also provided between the further rotation element 5 and adjacent rotation elements 7, 8 and 9, 10.
  • the distance 17 of the rotary elements 3 is shown to each other, which is provided between the outer edge of the coil 12 of the rotary member 3 and the core tube 1 1 of the immediately adjacent rotary member 3.
  • the pure distance 17 of the immediately adjacent rotation elements shown with the pure distance 17 between two immediately adjacent core tubes 1 1 results.
  • a distance 18 of the further rotation element 5 results for the first rotation element 7 or for the second rotation element 8 and in the same way for the penultimate rotation element 9 and the last rotation element 10.
  • the distance 17 of the rotary elements 3 is designed to be adjustable to each other. Furthermore, it is also not shown that the distance 18 of the further rotation element 5 to the immediately adjacent rotation element 3 or the rotation elements 7, 8 and / or 9, 10 is designed to be adjustable.
  • the distances 17, 18 can be adapted to the feed material 2 as well as to the loading of the device 1 caused by the feed material 2.
  • the respective spacing is to be considered that the smallest possible distance 17, 18 results in an increased self-cleaning effect or a significantly improved cleanliness of the exposed outside of the core tube 1 1.
  • the rotation elements 3 and the further rotation element 5 can be driven at the same angular speed. They are driven in the illustrated embodiment by the drive means 14, so that a synchronous operation and a constant angular velocity of the rotation elements 3 and the further rotation element 5 results.
  • This is particularly favored by the fact that the rotary elements 3 and the at least one further rotary element 5 via a drive means 15, formed in the illustrated embodiments as a roller chain, are interconnected and are therefore also driven together.
  • the spiral pitch of the rotary element 3 and the spiral pitch of the further rotary element 5 per 360 ° are at least substantially the same.
  • FIG. 2 shows that the device 1 carries out a separation of the feedstock 2 into at least two fractions.
  • an oversize fraction is deposited on top of the deck 4.
  • Another fraction - the fine grain fraction - can be deposited downwards between adjacent rotation elements 3. The fine grain fraction accordingly passes through the deck 4 and is carried away below the deck 4.
  • FIG. 6 also shows that a further fraction can be conveyed away transversely to the conveying direction X, wherein the further conveying direction extends along the axis of rotation or the longitudinal axis of the rotary elements 3.
  • a drop can take place via the ends of the rotary elements 3 and of the further rotary element 5.
  • Wrapping with elongated feed material 2 on the last rotation element 10 can be effectively prevented by the further rotation element 5, which acts as starsro- tationselement in the illustrated embodiment.
  • the deck 4, which is formed by the rotary elements 3, may be designed tiltable.
  • the holder 13, to which the rotation elements 3 and also the one or more further rotation elements 5 are fastened can be adjusted via a tilting device.
  • the height of the deck 4 may be designed to be adjustable in an embodiment not shown.
  • the deck 4 can form a curved separating surface.
  • the release surface that is, the top of the deck 4, at least substantially planar and / or straight.
  • the rotary elements 3 may be arranged in a curved separating surface, wherein at least three rotary elements 3 are not arranged in a common plane.
  • a further rotation element 5 below the deck 4, that is, below the rotation elements 3, can be arranged, in particular to increase the Disreini- tion of the rotary elements. 3
  • the feed material 2 is abandoned in the conveying direction X on the deck 4 formed by the rotation elements 3.
  • the feed material 2 can be applied to the first rotation element 7.
  • the feed material 2 is conveyed in the conveying direction X, wherein a fine grain fraction can be separated by the intermediate space 6 between immediately adjacent rotating elements 3.
  • An oversize fraction remains above the deck 4 and can be dropped in the conveying direction X and / or in a further conveying direction arranged at an angle to the conveying direction X, in the direction of the rotational or longitudinal axis of the rotating elements 3.
  • a further rotation element 5 rotates among the rotation elements 3.
  • the further rotary element 5 ensures that the rotary elements 3 are kept clean or (self-) cleaned and the interspace 6 or working space is cleaned between two immediately adjacent rotary elements 3 of the deck 4.
