Definitions

  • the invention relates to a crushing roller for roller crushers, consisting of a roller body and a plurality of crushing rings which are composed of segments and which are connected to the roller body by undercut, positively interacting projections and recesses which are formed continuously on the roller body in its longitudinal direction are.
  • a known crushing roller of this type (GB-PS 394 430)
  • four longitudinally extending, dovetail-shaped undercut grooves are provided on the circumference of the roller body, while the crushing ring segments, which each cover a half circumference of the roller body, have dovetail-shaped projections on their inner side which match the grooves wear.
  • a projection that fills the entire groove cross section is provided in the middle of the segment, while projections are provided at the segment ends that fill one half of a roller body groove, while the other half of a corresponding half projection of the adjacent one Crush ring segment is filled.
  • This design has the disadvantage that the crushing rings each have their smallest cross-section in the area of the groove boundaries of the roller body and thus in their central part or at least at such a large distance from their ends that considerable bending moments with a correspondingly high risk of breakage occur at these points.
  • the invention is therefore based on the object to provide a crushing roller of the type mentioned, whose ring segments are less ruchgefährdet b and may be sized accordingly more economical.
  • the solution according to the invention consists in that on the roller body in cross-section, T-shaped ribs and at the ends of the ring segments each an inner one under the web Rib matching projection and an upper projection are provided, wherein the upper projections adjacent within a ring substantially completely cover the associated rib of the roller body.
  • the ring segments according to the invention are less susceptible to breakage than the known ones when operating with hot crushed material, because the cross-sectional weakening caused by the holding members is arranged at their ends, where no significant bending moments occur.
  • the invention also leads to a very simple shape of the ring segments, so that it is economical to make them short, for example, that they only extend over a quarter of the roller circumference, while the previously known ring segments generally extend over half the roller circumference, which is corresponding leads to higher bending stress. Due to the shortness of the segments, thermal expansions can also have less of an impact. Thanks to their small size, the ring segments according to the invention can also be easily replaced without the need to remove the roller.
  • the segments 3 can be moved in the longitudinal direction of the crushing rollers and can be replaced in this way.
  • the crushing rings each arranged at the end of the roller are protected against sliding off the ribs 2 by suitable securing devices, for example by securing rings attached to the end of the roller body.
  • suitable securing devices for example by securing rings attached to the end of the roller body.
  • the invention does not require any continuous bolts for clamping the segments together because, owing to their brevity, these can be adequately held by the ribs of the roller body with a suitable width dimension.
  • the only figure shows a cross section through a crushing roller.
  • each pair of ribs 2 includes a group of segments 3 arranged axially one behind the other. Four segments 3 complement each other to form a crushing ring. At the end, each segment 3 is shaped to be complementary to half the cross-sectional shape of the associated rib 2 in such a way that each segment is held between two rib halves. Recesses 4 at the rib ends each take on the web end of the T-shaped rib cross section. Within the cut-out 4 there is a projection 5, which engages under the undercut of the rib 2 and causes the form-fitting hold between the rib and the segment. Above the cut-out 4, an upper projection 6 is provided which, together with the corresponding projection of the adjacent ring segment, protects the rib 2 in a protective manner. Expediently there is so much play
