  • the opening is provided in the bottom of the container.
  • the rotor axis may extend perpendicular to the opening plane.
  • the rotor projects only or at least partially into the container. This results in the opening, around the rotor, an annular passage for the material.
  • the outer shape of the rotor and / or the inner sides of the container have deviations from the circular shape, so that continuously changes in rotation of the rotor cross-sectional changes result in the region of the annular passage and / or in the container itself. Since the rotor extends partially into the container, an annular gap between the rotor and the container walls also results within the container.
  • the deviations from the circular shape are preferably produced by a polygonal design of the container and / or the rotor. Also possible is the deliberate arrangement of crushing or sieve elements which protrude into the gap or space at least partially filled by the material.
  • the rotor has a cross-section that tapers in the direction of the interior of the container.
  • the rotor may be conical or conical.
  • the rotor is formed with a largest cross section outside of the container and a smallest cross section within the container. With a conical shape thus protrudes the tip of the rotor into the container, while the base of the cone is outside the container or in the region of the opening.
  • the rotor has a plurality of mutually angled surfaces in the circumferential direction.
  • six or more, preferably eight mutually angled surfaces are provided in the circumferential direction.
  • the individual surfaces are inclined with a conical design of the rotor and against the rotor axis of rotation, for example by 30 to 60 °.

  • the annular or circumferential opening gap between rotor and container in the region of the opening has a width of 5 to 20 cm at a rotor diameter - also in the region of the opening - from 40 to 80 cm.
  • the opening is not completely adjacent to the walls of the container which are angled relative to one another, but that transition elements are arranged between the opening and the walls, in particular to form an opening gap annularly defined in this area.
  • the walls are designed and arranged to give a polygonal cross-section.
  • an opening adjoining the walls would have a polygonal outer circumference. Due to the arranged transition elements, the opening is now circular.
  • the transition elements can also be wear segments.

  • the impact elements are preferably arranged in the interior of the container, for example in the region of the transition between the circumferentially successive and mutually angled walls.
  • the impact elements can extend up to the transition elements and support or hold them. Transition elements and / or impact elements are exchangeable as wear parts by themselves or together. It is also possible to form the transition elements without adaptation to a circular opening or to achieve another non-circular shape.

  • the rotor is adjustable in its position relative to the container, in particular for changing the size or shape of the circulating Opening gap.
  • the rotor may be slidable into or out of the container, preferably together with the drive motor.
  • the drive is held on the outside of the container.
  • the drive can be held on the underside of the container or on walls near the bottom, in particular on arms which are connected by struts with the container.
