Definitions

  • the invention relates to a device for comminuting feed material according to the preamble of patent claim 1.
  • Such devices are assigned to the field of mechanical engineering, in particular the conversion of a starting material into a final product of a predetermined shape and size by means of comminution.
  • Such devices include disc mills, such as those from the DE 202 16 056 U1 are known.
  • Such disc mills have a rotor which cooperates within a housing with a stator.
  • the rotor consists essentially of a carrier disk, which is equipped over its outer peripheral portion with lying in the disk plane grinding tools.
  • the grinding tools are in axial distance while maintaining a Mahlspalts stationary stator opposite, which are arranged on the housing inner wall concentrically around the axis of rotation around.
  • Both rotor and stator tools can be formed by segments and are screwed to the carrier disk or the housing wall. This very time-consuming work not only increases the assembly costs for wear-related tool change, but also increases the proportion of downtime of the disc mill, which precludes efficient use. For this reason, disk mills already use rotor and stator tools, which consist of a complete ring that can be exchanged as a whole. Although the tool change times are thereby shortened, the profile of the grinding tools is limited to a substantially radial corrugation in terms of production technology.
  • the state of the art also includes mills, such as those in the EP 2 070 596 A1 are described.
  • the mill disclosed therein has a cone-shaped housing, the inner circumference of which is provided with a hollow truncated cone-shaped Mahlbahnmbi to form a stator.
  • Mahlbahnmbies coaxial with a rotor is arranged, whose rotor tools are formed by pendulum-mounted, radially aligned impact plates that stroke while maintaining a Mahlspalts on the inner circumference of the stator along.
  • the hollow truncated cone-shaped Mahlbahnnot forms the stator and is used as a whole in the housing, with a clamping ring on the larger diameter end face of the housing securing against axial changes in position of the grinding track insert guaranteed.
  • a substantially coaxial corrugation on the inner circumference of the grinding track insert is possible due to the monolithic design of the Mahlbahncons here.
  • Variations in the geometry of the corrugation in order to adapt the surface of the stator tools effective for the comminution to a specific feed material or to achieve a specific processing result are not possible.
  • the US 3,873,047 discloses a breaker with a rotor with clubs and a cylindrical housing surrounding the rotor. On the inner circumference of the housing a plurality of axially extending, an impact path forming crushing bars is arranged. The crushing bars are held in position on one side by a circumferential dovetail flange and on the other side by clips.
  • mill segments of a grinding path are arranged on the inner circumference of a cylindrical housing, which are defined between the housing bottom and the housing cover.
  • the object of the invention is to further develop known devices with regard to the shortest possible downtimes during the tool change and the greatest possible flexibility in the adaptation of the stator tools to the feed material and the properties of the end product.
  • the invention it is possible at the same time to satisfy the mutually exclusive requirements in the prior art for the fastest possible change of the comminution tools on the one hand and the greatest possible freedom in selecting the type of corrugation of the comminution tools within a device.
  • stator By segment-like design of the stator, it is possible that two successive segments have a different corrugation, whereby both the intensity of the crushing and the residence time of the feed material in the crushing can be controlled. At the same time the segments are placed for mounting only in the stator and then fixed with a clamping element in position. In this way, extremely short tool change-related downtimes can be achieved.
  • the invention enables a more economical operation of the device according to the invention by a simplified tool change with simultaneous qualitative improvement of the processing result due to the ability to better adapt the stator to the respective conditions.
  • the Fig. 1 and 2 give a vertical and horizontal section through a device according to the invention in the form of a mill 1 again.
  • a frame-like, made of steel profiles substructure 2 which forms with its top a horizontal platform 3 with a central opening 4.

  • the annular flange 10 serves as a support and Attachment of a concentric bearing ring 11, which is formed angularly in cross-section and the horizontal leg is connected to the annular flange 10.
  • the housing 6 continues in a bell-shaped, hollow truncated cone-shaped upper part 12, the larger diameter underside of which is open and assigned to the lower part 7 and whose smaller diameter upper side has an opening 14 which is bounded by a circumferential, radially inwardly pointing collar 13.
