Definitions

  • the present invention relates to a material processing machine according to the preamble of the independent claim.
  • Another known arrangement is a shredder formed, in which the stator on a multi-point bearing is held.
  • the pretense of all Fasteners one after the other allowed the Align the stator parallel to the rotor so that one over the To obtain a grinding path with a uniform gap distance. On the other hand the gap distance can be adjusted.
  • stator during gap adjustment does not remain parallel to the rotor, but against it is tilted because the attachment points only one after the other can be adjusted. This is especially the case with minor ones Gap distances problematic, because here a slight one Tilting can lead to the opposite Touch the grinding elements of the stator and rotor.
  • the aim of the present invention is to create something new for to provide the commercial application.
  • the arrangement is advantageously in the door on the machine housing integrated.
  • the door attached to the machine housing by means of swivel joints.
  • the entire arrangement is pivoted away from the rotor and when the door is closed, the stator is in immediate Arranged close to and aligned with the rotor. It is easily possible with conventional door hinges, a stator aligned once parallel to the rotor together with its holder always reproducible in the same Swivel position back.
  • the stator is preferred to achieve parallel alignment carried on an adjustable multi-point attachment, with which he is in the generally parallel alignment Tilt can be adjusted.
  • a multi-point attachment can manufacturing tolerances of rotor disc, Stator and / or grinding elements, rotor axis misalignments etc. can be compensated without problems.
  • the multi-point attachment is preferably designed at least as a three-point fastening, the stator being attached by means of tension and / or compression screws and with which at least two are separated from each other Attachment points a tilt is possible.
  • the multi-point attachment can in particular the stator wear indirectly, namely that the multi-point attachment a bearing, which with the stator together in the alignment generally parallel to the rotor is adjusted.
  • the multi-point attachment is preferred on the outside of one machine door pivotable in front of the rotor.
  • a preferred fastening is formed with a thread, in which the one with a suitable external thread Stator can be rotated back and forth.
  • the stator is moved towards or away from the rotor.
  • the general alignment of the stator to the rotor remains received because even if the stator and rotor are not complete aligned coaxially, the stator will tilt nevertheless safely avoided, since only the point of closest approach rotate on the grinding track by rotating the stator becomes.
  • the rotation of the stator is typically 15 to 30 ° may be possible, and the gap distance between Vary 0.2 and 4 mm.
  • An adjusting means is preferably provided, which on the one hand attacks on the attachment and on the other hand on the stator. Between the points of attack formed as supports or abutments an actuator is provided, which the abutment and support moved towards or away from each other, and so the Gap distance between stator and rotor changed.
  • the actuator can be formed by a fine-thread spindle be whose thread is generally perpendicular to the thread of the Bearing stands, with abutments and supports for the fine-thread spindle on bracket and storage are arranged so that the rotation of the spindle reciprocates the stator causes.
  • stator is radially outside of it Grinding path is held. In general, it is advantageous to Keep stator radially spaced from its axis because so the strong forces on the stator are best absorbed can.
  • 1 comprises a comminution machine, generally designated 1 1 as a material processor Machine with a housing 2, a rotor 3 and an opposite one Stator 4.
  • the rotor 3 is as by means of an electric motor (not shown) driven rotor disc formed on her radially outer circumference grinding track elements 3a carries out highly wear-resistant material and made for easier Exchange attached to the rotor disk by means of bolts 5a are.
  • the axis 6 In the middle of the rotor disk 3, this is on an axis 6 attached by means of a bolt 5b.
  • the axis 6 passes through the housing 2 and is rotatable in a low-friction bearing 7 stored.
  • the low-friction bearing 7 is for a fixed axial positioning of the rotor disk 3 is formed.
  • a stator disk 4 is located opposite the rotor disk 3 provided, which also has grinding track elements on its outer circumference 4a carries, which are fastened with bolts 5c, as well further wear elements 9, the radially inside of the grinding track elements 4a lie.
  • a Through hole 10 is provided, which for a sufficient Grist flow is dimensioned, which is via a filling path 11 is passed through the hole 10.
  • the grinding track elements 4a of the stator and the grinding track elements 5a of the rotor are opposite and on top of each other facing closely adjacent with a gap distance at the youngest point between 0.2 and 4 mm.
  • the stator disc 4 is preferably on it as shown bead-shaped circumference 4b provided with an external thread 4c, which revolves around the circumference.
  • the external thread 4c of the stator disk 4 meshes with a suitable one Internal thread 22 of a holder 23, which the stator surrounds in a ring.
  • the annular holder 23 is adjustable on the pivotable 2 hinged door frames held on the machine housing. For adjustment serve the pressure and / or tension screws 24a, 24b, which together with the third screw 24c equidistant are distributed over the scope.
  • the third screw of the arrangement 24c is like the other two pressure and / or tension screws trained, but only has a holding function.
  • the threaded spindle 26 is at its end with a Ball provided in a corresponding hole 25a of the bearing 25 is arranged. On their opposite At the end, the spindle 26 has a handwheel 29.
  • the screws 24a and 24b are adjusted until a uniform over the entire circumference of the stator disc Gap distance to rotor 3 results. So that the stator is parallel aligned with the rotor. Then the threaded spindle 26 turned until a desired gap distance between Rotor disc 3 and stator disc 4 has set. Possibly now the threaded spindle with a lock nut countered and thus fixed the gap distance. Then it will be the inlet funnel 11 is pushed into the central opening and the machine is ready for use.
  • a change in the regrind is desired in the company because, for example, a finer size reduction is desired, can loosen the lock nut provided on the threaded spindle and the gap is adjusted while the machine is running become.
  • the typical design of the thread 22 and the Fine-thread spindle 26 allows adjustment of the gap for example 0.2 to 4 mm.
  • the threaded spindle can if necessary also provided with a scale or a vernier to show the gap distance.
  • the gap distance can be set by pressing of a single control element carried out without problems and is so especially from unskilled workers feasible.
  • the gap distance is not simply a single one Times to a fixed setpoint, rather, regulations can also be provided according to the invention with which the setting in operation automatically is changed.
  • the gap distance can be optically or otherwise sampled, the temperature or fineness of the emerging regrind or certain properties such as moisture content, hardness, etc. of the supplied material be determined and in control and / or control loop an adjustment of the gap distance can be made.
