Definitions

  • the invention relates to a device for the treatment of Asphaltaufbruch according to the preamble of claim 1.
  • the invention further relates to a method for the separation of bitumen parts from Asphaltaufbruch.
  • Asphalt concrete as it is used in particular in road construction, consists essentially of chippings, so crushed natural stone of various particle sizes and bitumen as a binder and is processed in the heated state at about 180 degrees Celsius. Under Asphaltaufbruch solid, cooled Asphaltbrocken, as incurred in road or bridge construction during repair work understood.
  • the invention aims to remedy this situation.
  • the invention is based on the object to provide a device for the treatment of Asphaltaufbruch, which allows an economic separation of adhering to the chips parts bitumen.
  • this object is achieved in that the separating elements are formed by flexible impact elements.
  • the invention provides a device for the treatment of asphalt break-up, which enables an economic separation of the bitumen adhering to the split parts.
  • the flexible impact elements impulses are applied to the bitumen split composite parts, which cause a separation of the bitumen from the chips parts by the different material properties.
  • the flexible impact elements are metal chains that are connected to the shaft.
  • Such chains are inexpensive and have a long service life.
  • the striking elements are releasably connected to the shaft. This allows the exchange of worn impact elements.
  • a screening device preferably in the form of a vibrating screen, is connected downstream of the separator for separating the bitumen and grit fractions of the asphalt.
  • separators are known in the art.
  • the lighter bitumen particles are separated from the heavier split parts by means of vibrating sieves.
  • the invention is further based on the object to provide a method for the treatment of asphalt break-up, which allows an economic separation of adhering to the chips parts bitumen.
  • this object is achieved in that the asphalt asphalt is first crushed in a crusher and then the bitumen split composite parts are acted upon by means of rotating flexible impact elements with pulses.
  • the fractions of purified grit and bitumen residue are subsequently separated via a sieve device.
  • a split fraction can be achieved, which can be used to a high extent in the production of the base course in road construction.
  • the bitumen content can also be reused in the asphalt mixture.
  • the embodiment according to FIG. 1 selected device consists essentially of a housing 1, in which a shaft 2 is arranged, which is provided with two axially arranged rows of flexible metal chains 3.
  • the housing 1 is formed substantially cuboid. On its upper side, a hopper 11 is arranged to supply the asphalt material. At its bottom opposite the funnel 11, a material outlet 12 is arranged, which is provided with a sieve device 13.
  • the shaft 2 is connected to a - not shown - drive unit, via which the shaft 2 is rotatable.
  • a - not shown - drive unit via which the shaft 2 is rotatable.
  • two axially extending rows of eyelets 21 are formed in the embodiment diametrically opposite each other, which serve to receive the metal chains 3.
