Definitions

  • the invention relates to a rotor for a crushing machine, wherein the rotor is formed of a rotor shaft with spaced in the axial direction of the rotor shaft support disks, rotatably mounted between support disks of the rotor striking tools and protective caps, wherein the protective caps are attached to or between support disks, wherein a A plurality of radially or between the support disks arranged protective caps a roller-shaped shell of the rotor is formed with openings for the striking tools.
  • Crushing machines are known from the prior art, which, inter alia, have a rotor consisting of disks.
  • Such comminution machines are also referred to as so-called hammer crushers, since rotatable striking tools or hammers are mounted between the disks or support disks, by means of which comminution of, for example, metal scrap, plastic waste, wood waste or similar fractions can take place.
  • comminution machines are also referred to as so-called hammer crushers, since rotatable striking tools or hammers are mounted between the disks or support disks, by means of which comminution of, for example, metal scrap, plastic waste, wood waste or similar fractions can take place.
  • outer surfaces of the discs can suffer considerable damage due to a collision of material during comminution, it is known that the discs to be provided with a protective agent.
  • the protective means can extend over a length of the rotor and thus form a wear-resistant, roller-shaped jacket for the disks of the rotor
  • the protective means are regularly designed as so-called protective caps and, like the hammers of the rotor, are subject to wear even though they are not actively involved in the comminuting process.
  • the protective caps are therefore also known as inactive wear parts.
  • the protective caps are fastened together with the hammers, which are also referred to as active wear parts, on an axle which is passed through the washers so that the hammers can swing freely and the protective caps substantially completely clear the spaces between the hammers fill out. By removing or extracting the axle from the support disks, the protective caps and the hammers can be exchanged or replaced in case of advanced wear.
  • the basic structure of such a rotor of a crushing machine is for example from the DE 2 605 751 A1 known.
  • Protective caps are known, which are not molded as one piece caps, but in several parts.
  • a partial jacket surface of these protective caps is formed from a bent and hardened sheet steel, to which a connecting plate of structural steel is welded on the inside and in which a hub is designed for attachment to an axle. So can also one comparatively hard, wear-protected surface of the protective cap and a comparatively tough and soft suspension of the same are formed.
  • a disadvantage of such protective caps is that the steel sheet used can have segregations caused by a manufacturing process of the steel sheet. By bending the steel sheet it comes to tensile and compressive stresses within the steel sheet, which can cause bending cracks. As has been shown in practice, cracks on the protective caps preferably also occur in the region of segregations of the steel sheet, in particular under the influence of tensile and compressive stresses during bending. These cracks then cause premature failure or wear of the protective caps.
  • the present invention is therefore based on the object to propose a rotor for a crushing machine, which is universally applicable and has a long service life.
  • the rotor is formed of a rotor shaft with axially spaced apart the rotor shaft spaced support disks, rotatably mounted between the support disks of the rotor striking tools and protective caps, wherein the protective caps are attached to or between support disks, wherein a plurality of radially on or between the support disks arranged protective caps a roller-shaped shell of the rotor is formed with openings for the impact tools, wherein the jacket forms impact edges.
  • feed material can first be coarsely crushed by means of the impact tools or hammers of the rotor, whereby a finer size reduction of the coarsely comminuted material can be carried out simultaneously by means of the impact edges.
  • the finer size reduction results on the one hand by a striking effect of the impact edges on the feed material and on the other hand by an impact effect of the impact edges.
  • the feed material is thus conveyed away from the jacket of the rotor, into a comminuting space. Unlike an all-round shell, the feedstock can not slide along the shell upon rotation of the rotor and cause abrasive wear. A concentration of feed material directly on the jacket is thus prevented.
  • the impact edges may be distributed at regular, radial intervals over the mantle. Thus, a uniform concentricity of the rotor can be ensured.
  • the impact edges may be formed extending in the axial direction over the jacket.
  • the impact edges may extend continuously over the jacket axis parallel to a rotational axis of the rotor or be interrupted in sections by impact tools.
  • the impact edges can be arranged relative to each other in the radial and axial directions offset from each other on the mantle or extend helically over the mantle.
  • the impact edges can form a V-shaped pattern on the shell, so that the feed material can be concentrated in a central region of the shell.
  • the impact edge may be formed so that an average outer diameter of the shell of the striking edge is radially überragbar. Consequently, the protective caps forming the shell project beyond the mean outer diameter of the jacket, each with their impact edge.
  • no feedstock can concentrate directly on the mantle, since the feed material rebounds constantly from the striking edges and is conveyed in the direction of, for example, hammers.
  • the protective cap can also have an impact edge.
  • the surface portions relative to each other may be arranged so that a relative to the rotor axially extending edge is formed on the protective cap.
  • the impact edge or impact edge can then cause a rebound of feed material from the jacket when the rotor rotates.
  • An undesirable concentration of feed directly at the Jacket surface can be avoided alone by the formation of the protective caps.
  • the impact edge may be formed by an application of a wear material.
  • the impact edge can be repaired, for example, even when worn by a new order of wear material.
  • the wear material may be a coating or material applied by simple build-up welding.
  • the impact edge may be formed by at least one blow bar.
  • the blow bar can then be a strip-shaped component or element. It is basically irrelevant whether the blow bar runs as an element over the entire jacket of the rotor or only a protective cap. In this case, then a plurality of protective caps each have blow bars. A blow bar can project beyond the jacket or a protective cap in a comminution chamber, so that the blow bar can come into direct contact with feed material during a rotation of the rotor.
  • the blow bar may consist of a cast material, a fine-grained structural steel or a ceramic insert, wherein the blow bar may have a hardness of 350 to 550 Brinell (HB).
  • the blow bar can also have a hardness of 430 to 550 Brinell.
  • the hardness of the blow bar or the material can be selected so that the blow bar is adapted to the respective feed material.
  • the blow bar can be attached to the blow bar holder in a form-fitting and replaceable manner. Since the blow bar is exposed due to their exposed position on the jacket of a particularly high stress, the blow bar can then be easily replaced according to a wear of the blow bar. Depending on the design of the positive fastening of the blow bar on the protective cap It may not even be necessary to disassemble the protective cap from the rotor, but the respective worn blow bars can be disassembled for themselves by the rotor.
  • the protective cap may be formed from a plurality of elements joined together.
  • the elements may preferably be joined by welding, although other suitable joining techniques may be provided. So it is also possible to form the elements each of materials that are most suitable for a determination of the elements.
  • the protective caps can form a substantially closed jacket, which is broken through the openings for the impact tools or hammers.
  • the protective caps can be distributed in the axial as well as in the radial direction relative to the rotor over the shell and form these by respective segment-shaped partial circumferential surfaces.
  • the segment-shaped partial circumferential surfaces can be of different size or shape.
  • impact tools do not necessarily have to be arranged between all support disks of the rotor. It is essential, however, that the partial jacket surface of the protective cap or of the respective protective caps of the rotor can be formed from at least two planar surface sections.
  • planar surface sections can be used to form the partial jacket surface, it is not necessary to bend a steel sheet to form a partial lateral surface adapted to the rotor or its circular cylindrical form. Any cracking caused by existing segregations in the steel sheet and tensile and compressive stress during bending can thus be effectively avoided.
  • the protective cap can then also be produced in a particularly cost-effective manner, since it is possible to dispense with a complex bending of a comparatively thick steel sheet associated with a machine insert. So it is also possible a significant cost savings in the production of the cap and an extension of a life of the cap to achieve.
  • the protective cap can also form more than two planar surface sections. It is essential that the entire partial circumferential surface of the protective cap can be composed almost completely or predominantly of flat surface sections.
  • the surface sections are each formed from a plate-shaped or straight-shaped wear element.
  • the plate-shaped Schl adoptedelement can be particularly easily made of a steel sheet by cutting.
  • the plate-shaped wear element can then also be subjected to a temperature treatment, such as, for example, annealing, hardening and / or tempering. A possible deformation of the plate-shaped Schlndrii due to the temperature treatment is not important in contrast to curved Schlndriin.
  • the surface portions may preferably be arranged such that surface normals of the surface portions extend relative to each other at an angle ⁇ .
  • the angle ⁇ can be a deviating from 0 °, acute angle.
  • the angle ⁇ may be defined by 360 ° divided by the number of area sections relative to a circumference of the shell.
  • the angle ⁇ can then be the same for all the protective caps forming the sheath.
  • the surface portions may then each have a respect to the circumference of the shell same radial length.
  • the flat surface sections are made even easier.
  • the protective cap can be designed so that surface normal of the surface portions can intersect in a rotational axis of the rotor. Thus, a possible imbalance of the rotor can be prevented wherein the jacket of the rotor can be further approximated to a circular shape.
  • the blow bar receptacle can be particularly easily formed from two profile elements, wherein the profile elements can be arranged between or on the Schl hinderriin, wherein the profile elements can also form a receiving groove for the blow bar.
  • the formation of the receiving groove is particularly advantageous since the blow bar can then at least partially inserted into the receiving groove and secured in this.
  • the receiving groove is easy to produce by arranging the profile elements in parallel at a distance relative to each other. If the profile elements are arranged between the Schl hinderettin, the profile elements can also form a surface portion of the shell. Furthermore, a particularly stable attachment of the profile elements can result from the arrangement between the wear elements. For example, the profile elements can be welded to the Schludgen.
  • a longitudinal groove can be formed in the blow bar, in which engages a projection within the receiving groove. Accordingly, a positive reception or attachment of the blow bar in the receiving groove can be realized particularly easily.
  • the blow bar can then be easily inserted into the longitudinal groove. By the projection within the receiving groove then falling out of the blow bar from the receiving groove in the radial direction is reliably prevented.
  • the projection may be formed, for example, in the manner of a nose, wherein the nose can then engage in the longitudinal groove, which has a matching shape.
  • an application coating may be formed on the profile elements and at least partially on the surface sections of the wear elements adjacent to the profile elements.
  • Such an application coating may consist of a wear-reducing, suitable coating material.
  • the application coating can also be formed by welding material onto the profile elements and the adjacent surface sections.
  • the protective cap can form a fastening web with a hub for fastening the protective cap on or between support disks.
  • the fastening web can then be arranged in the radial direction relative to a surface section at right angles to this. If the rotor has axles which are inserted through openings of the support disks or the support disks themselves form axles or projections, the protective cap can easily be attached to the hub on an axle and thus securely fastened.
  • the wear elements are welded directly to each other.
  • a completely closed partial circumferential surface can be formed for a protective cap.
  • the protective cap is formed of a plurality of elements, all elements can be welded together.
  • the impact edge can be formed by a weld of the Schlndiata.
  • the weld may have a comparatively high hardness compared to the material of the surface sections. Since the impact edge is expected to be more stressed than the surface sections, so premature wear of the striking edge can be avoided.
  • the wear elements can further have a hardness of 350 to 550 Brinell (HB).
  • HB Brinell
  • the hardness can be 430 to 550 Brinell. This ensures that the wear elements or the surface sections of the protective cap formed by the wear elements are sufficiently resistant to damage and wear.
  • the Schl mustieri can be particularly wear resistant and yet inexpensive to produce if they are made of fine-grained structural steel. Fine-grained structural steel is also particularly suitable for a temperature treatment to achieve a desired hardness.
  • the protective cap may have support elements, wherein the support elements may be arranged on a bearing side of the wear elements facing away from the partial jacket surface, such that the protective cap can be adapted to a shape of the support disks.
  • the protective caps can then be adapted by means of the support elements to the respective outer contour of the support disks so that the protective caps each rest on at least two points on the support disks or their outer contour.
  • the protective caps can then be supported by means of the support elements on the support disks, wherein moreover a tilting of the protective caps or an undesirable relative movement to the support disks can be easily avoided.
  • it can be provided to use three support elements for supporting a protective cap on an outer contour of a support disk.
  • the protective cap can also rest on the support disks at other points of the protective cap on which no support elements are arranged.
  • a fastening web of the protective cap may be formed of a connecting plate for the Schl hinderimplantation, wherein the connecting plate may also be reinforced with reinforcing plates. Consequently, the Schl hinderieri can be connected to each other via the fastening web, wherein the Schl hinderieri can be welded to the fastening web or the connecting plate.
  • the reinforcing plates can be arranged on both sides of the connecting plate and also connected or joined with two Schl possessettin. So it is also possible a special To realize good attachment of the protective cap on, for example, an axis of a rotor, since the axis may be passed through a through hole in the connecting plate and the reinforcing plates.
  • the protective cap can also be designed as a one-piece cast element, wherein the protective cap can then also have the shape of a welded or otherwise joined protective cap.
  • the advantages arising from the planar surface sections with regard to a treatment of the feed material can also be used for cast protective caps.
  • the jacket of the rotor may be polygonal in the radial direction, based on a cross section of the rotor.
