Definitions

  • the invention relates to a device for the mechanical comminution of materials, in particular material conglomerates of different materials.
  • the comminution device comprises a vertically extending comminution chamber with an upper feed side and a downwardly pointing outlet side, which comminution chamber is surrounded by a particular circular cylindrical and / or conically downwardly expanded comminution chamber wall.

  • the rotor carries impact tools which, at least during operation, extend at least substantially radially into the crushing chamber, e.g. Batons or chains.
  • the rotor is held stationary with respect to a support base of the comminution device, on which support base the comminution chamber wall is also supported.
  • Such shredders have vertically aligned the crushing chamber so that the feed side faces up and the outlet side down.
  • the crushing chamber wall is held vertically adjustable relative to the support base in the axial direction R of the comminuting device, which lifting device has a first working position, in which the lower edge of the comminution chamber wall is arranged close to the support base or an associated part, in particular abuts the support base , and a maintenance position in which the lower edge of the crushing wall is vertically raised above at least one of the impact tools of the crushing device.
  • the complete crushing chamber wall is height adjustable held by the lifting device.
  • the lifting device comprises at least one hydraulic cylinder, which is fastened in a stationary manner in connection with the support base, is preferably fastened directly to the support base, and engages on the cylinder chamber wall or an associated mounting part.

  • the lifting device is mounted on the support base, i. its U nterseite is connected to the support base, which has the advantage that the support base carries all the essential components of the crushing device and thus the crushing device is realized as an integrated arrangement.
  • the crushing device In the raised maintenance position, at least one of the striking tools, but preferably all impact tools of the rotor or the rotors is exposed, so that all impact tools of the crushing device can be easily replaced.
  • the lower edge of the crushing chamber wall preferably rests on or on the supporting base, with which the crushing chamber is sealed to the supporting base, in which case preferably the outlet is arranged in the region or in the supporting base.
  • the crushing device has an electrical circuit breaker for its drive, which is in contact with the support base and on the other with the separation chamber wall or with contact elements fixedly connected to these elements. In this way, you can only put the crusher in operation when the lifting device is in the working position, which precludes the impact tools are freely accessible when the crusher is put into operation.
  • the motor (s) for driving the rotor (s) can therefore only start when the circuit breaker is closed, which in turn is only possible when the lifting device is in the working position. Such an embodiment of the invention is thus very safe to work.
  • the crushing device includes a rotor / rotors speed detecting device that detects whether or not the rotors are rotating, which speed detecting device is capable of giving an enabling signal when all the rotors are stationary.
  • the crushing device includes a safety circuit that allows the power supply to drive the lifting device only when the release signal is present.
  • a simple electrical device assures the operation of the lifting device that lifting the cylinders of the crushing chamber wall with the rotor running is impossible. This measure also serves considerably the safety of the crushing device. Together with the electrical disconnector, this ensures 100% working safety.
  • the crushing chamber wall is formed as a cylindrical wall with a circular or polygonal base, as it is commonly used in crushing devices. Such a crushing chamber wall is on the one hand easy to manufacture and on the other hand in a simple manner by a lifting device between the maintenance position and the working position movable.
  • a task cone is arranged in connection with the crushing chamber wall on the supply side, which cooperates with a feed hopper which is movable by the lifting device separately and / or in connection with the lifting of the crushing chamber wall.
  • a feed hopper which is movable by the lifting device separately and / or in connection with the lifting of the crushing chamber wall.
  • an air flow device for guiding a particle / air mixture produced in the comminution chamber is arranged in connection with the comminution chamber.
  • This air flow device has at least one coaxial with the axis of the crushing chamber arranged fan rotor, which is driven by its own fan drive.
  • the fan rotor can thus be rotated independently of the rotors of the crushing device.
  • the fan rotor is located under the lower edge of the crushing chamber wall, when this is lifted by the lifting device in the maintenance position. In this way, the fan rotor of the air flow device can be easily maintained.
  • each rotor of the comminuting device has a fastening device for releasable attachment of the percussion tools, which allows easy replacement of the impact tools when the comminution chamber wall is raised.
  • a flat distributor bottom is arranged on or in the support base on the outlet side of the crushing chamber. This allows a simple way to provide at the support base containers for receiving the different material fractions, so that the crushing device requires no additional material or particle guiding devices.
  • FIG. 1 shows a first embodiment of a crushing device with the lifting device in the working position.
  • Fig. 2 is a perspective view of the first embodiment of the invention with the lifting device in the maintenance position, and
  • Fig. 3 shows a second embodiment of a crushing device in which can be adjusted relative to a task cone with the lifting device and the distance of an inlet funnel.

  • blow bars made of metal can be used as impact tools and chains or pivotally suspended batons.
  • a fan rotor 26 is formed, which is arranged in the support base 20 under a receiving plate 30 arranged on the upper side of the support base 20, in order to supply the particulate particles, which are formed during comminution, to a particular lateral outlet for further processing. to deposit there the valuable mineral components.
  • the outlet is preferably arranged at the same height as the fan rotor in order to effectively remove the comminuted particles.
