Definitions

  • the invention relates to a comminution device with a funnel-like container, in the outlet area of which two crusher rollers parallel to one another are mounted, which can be driven in opposite directions.
  • the crushing rollers of known shredding devices are constructed in a wide variety of ways, whereby a basic principle is always based on that on the outer circumference protruding elements of the crushing rollers are provided, the elements of adjacent rollers intermeshing. In this way, the material to be shredded introduced between the rolls is both gripped by the rolls and transported to the roll gap, and also shredded by the interaction of the two rolls. In order to ensure satisfactory operation, attempts were made to adapt the shape of the crushing rollers to the materials to be shredded. There is always the problem that the breaker rollers either cannot adequately shred the objects to be shredded or that the breaker rolls become blocked or clogged by the fragments that result from shredding. The prior art thus shows shredding devices which are not suitable for mixed materials, but rather can only be used in each case for shredding wood, metal or plastic.
  • the invention has for its object to provide a shredding device of the type mentioned, which can be used universally with a simple structure and easy handling and in particular enables the shredding of mixed materials with fast and economical operation.
  • the object is achieved in that the crusher roller has a cylindrical base body, to which a plurality of spaced-apart disk elements are fastened, on the peripheral region of which a number of crusher elements are attached.
  • the shredding device according to the invention is characterized by a number of considerable advantages.
  • the described design of the crusher rollers makes it possible to use a wide variety of materials, including mixed materials shred in a reliable manner. It can be observed that a very regular grain size is obtained.
  • the crusher elements arranged on the outer circumference of the individual disk elements result in a self-cleaning effect, so that the comminution device according to the invention can be operated without interruptions over a long period of time. Furthermore, the configuration of the crusher rollers according to the invention ensures a high degree of functional reliability, since foreign bodies which are admixed with the material to be comminuted do not lead to a malfunction. Foreign objects of this type can, for example, be metallic components which are connected to the wooden parts to be comminuted.
  • the shredding device according to the invention allows the processing of a wide variety of different materials, in particular it is possible to process wood, pallets, waste, tree stumps, root pieces or the like. Plastics and compostable materials can also be shredded. In any case, the crushed end product produces a very fine grain.
  • the comminution device is constructed such that the disk elements of the two crusher rollers and thus the crusher elements are offset with respect to one another in the longitudinal axis of the crusher shafts.
  • the crusher elements thus each engage in opposite spaces of the adjacent crusher roller, so that these spaces are cleaned of crushed particles.
  • the overlap of the crusher elements thus leads to the self-cleaning effect described.
  • each disk element can be attached to each disk element, preferably four or six crusher elements are provided.
  • the breaker element is plate-shaped and arranged essentially in a tangential plane of the disk element. It is also possible to position the crusher element slightly on the inside to the tangential plane. The oblique configuration of the crusher element thus results in a linear force on the workpiece to be shredded, the radially inner side of the crusher element leads to a squeezing movement of the workpiece into the nip.
  • the crusher element can be provided with a cutting-like bevel on its front side.
  • the crusher element is mounted by means of a support body lying in the plane of the disk element.
  • the support body can be arranged in front of the crusher element in relation to the working direction of rotation of the crusher roller. It can furthermore be advantageous if the support body has a radially oriented front edge and a segment of a circle arranged in front of the crusher element. In this way, the support body serves not only to support the crusher element, but also at the same time to shred materials, the support body acting like a blade, as is the case, for example, with a circular saw blade. It is beneficial if the diameter the area of the support body which is in the form of a segment of a circle is substantially identical to the circle described by the front edge of the crusher element.
  • the shredding device thus brings about a multiple shredding of the materials in the configuration of the crusher rollers described last.
  • crushing takes place in the longitudinal direction of the crusher rollers through the individual crusher elements and their cutting edges, which are each arranged parallel to the crusher roller axis.
  • the support bodies lead to a dismemberment of the respective workpiece into sections which correspond in length to the distance between the individual disk elements.
  • the interlocking of the crusher elements ensures reliable cleaning of the spaces between the disc elements. It is particularly advantageous if the disk elements of the crusher rollers and the crusher elements are dimensioned such that a crusher element of one crusher roller engages in the space between adjacent disk elements of the other crusher roller.
  • the individual crusher elements of adjacent disc elements are preferably offset in the circumferential direction, so that a side view of the crusher roller results in a spiral arrangement of the individual crusher elements. This ensures uniform power transmission and prevents the crusher rollers from rattling. At the same time, it is ensured that no material is transported through the nip without being crushed.
  • the breaker rollers can preferably be driven in both directions of rotation. In relation to the roll gap formed by the crusher rolls, it is possible to in the crusher rolls until a predetermined circumferential force is reached To move the working direction towards each other. If a workpiece is clamped between the crusher rollers that cannot be shredded, the crusher rollers are subsequently rotated in the opposite direction for a predetermined period of time in order to clear the roll gap in this way.
  • the shredding device according to the invention can either be designed to be portable or stationary.
  • FIG. 1 and 2 each show an embodiment of the comminution device according to the invention in side view and plan view.
  • This comprises a funnel-like container 1, in the outlet area 2 two crusher rollers 3 and 4 are arranged.
  • the crusher rollers 3 and 4 are rotatably mounted parallel to one another and are each driven in opposite directions by means of a drive, not shown in detail.
  • a belt conveyor 13 is provided below the outlet area 2, by means of which the comminuted material can be transported into a container or onto a heap.
  • the two crusher rollers 3 and 4 are firmly coupled to one another via a gear for synchronous movement; the drive can take place, for example, via a hydraulic motor 14 which is only shown schematically. Furthermore, safety clutches or the like can be provided in order to prevent overloading of the device.
  • 3 shows an end view of the device according to the invention, from which the funnel-like design of the container 1 and the arrangement of the crusher rollers 3, 4 results.
  • FIG. 4 and 5 a first embodiment of the crusher rollers 3 and 4 according to the invention is shown.
  • the crushing rollers are shown in FIG. 4, as well as in FIG. 6, with an increased mutual distance in order to be able to better describe the structure.
  • the crusher rollers 3 and 4 consist of an essentially cylindrical base body 5, which is provided with suitable bearing and drive devices (not shown).
  • a large number of disk elements 6 are fastened to the base body 5 and, on their outer circumference, as can be seen in particular from FIG. 5, carry a plurality of crusher elements 7.
  • the breaker elements 7 are each plate-shaped and arranged essentially in a tangential plane to the respective disc element 6.
  • FIG. 5 a view is shown in which the roller rotates in the counterclockwise direction.
  • a support body 9 is arranged in front of each of the crusher elements 7 and has a radial front edge 10 and a region 11 in the form of a segment of a circle.
  • the front edge 8 of each crusher element 7 is chamfered in a cutting shape.
  • the exemplary embodiment shown in FIGS. 6 and 7 differs from the exemplary embodiment according to FIGS. 4 and 5 only in that instead of six crusher elements 7, only four crusher elements 7 are provided.
