  • the present invention relates to a vibrating screening machine which is particularly suitable for classifying bulk materials, in particular solid materials such as e.g. Stones, and the like is suitable, and which has a housing with two side walls, to which at least one screen deck is attached.
  • a vibrating screening machine which is particularly suitable for classifying bulk materials, in particular solid materials such as e.g. Stones, and the like is suitable, and which has a housing with two side walls, to which at least one screen deck is attached.
  • Schwingsieb- or Vibrationssiebmaschinen have become known, for example, are suitable for classification, for pre-separation, for deflagration, drainage and / or eg for FremdMechabsiebung.
  • classifying there is generally a separation of the feed stream into two or more equivalent products, which are separated according to grain size.
  • the goal is to separate material that is to be removed from the further processing process, with a screening machine.
  • a typical example of this is the cup relief before the primary crusher in the quarry. Stones whose grain size falls below a predetermined level, should be passed to the primary crusher to relieve the crusher.
  • Deflagration is the classifying process in which interfering fine particles are separated or emaciated from a product. Screening machines for foreign matter screening are used to sift out sporadically occurring foreign substances in the feed material.
  • Vibrating screens for pre-separation of different power generally have the same working principle, but are dimensioned differently.
  • the disadvantage is that each Schwingsiebmaschine practically represents a redesign, even if the same vibration principles are used and the machine is provided for the same weg.
