  • the design of the impact device is particularly suitable viewed as a ring inserted into the housing. Because of this insert, it is not just the housing configuration independent of the impact device, but it can also systems that are basically similar in structure own, be retrofitted accordingly. It's about it also advantageous to replace the ring in the housing hold so that if you use it over a longer period of time wear occurs the impact device is replaced can be. Another advantage of interchangeability is that depending on the type of grain or other parameters Impact devices with different cone angles can be used.
  • Impact device limited in the longitudinal direction of the axis of rotation adjustable.
  • This adjustability of the impact device in relation to the rotor has the advantage that the area which mainly acts on the goods to be processed is changeable and thus a more uniform Wear over the entire axial length of the impact device can be achieved. So that the service life of the impact device significantly extended.

Since the lid 3 is removable from the housing 2, the impact device 10 easily accessible so that it is convenient to the impact device 10 to be arranged in the housing 2 such that the impact device 10 is easy to remove or reinsert. In this way it is possible to exchange the Impact device 10 against another, for example one Impact device which has a different angle of inclination or in the event of wear of the baffle 11 against one new impact device.
  • a funnel 15 is held by the cover 3, which is for input of the grain to be peeled.
  • the Funnel 15 connects to a metering tube 16 through which the grain to be peeled is fed to the center of the spreading disc 7 becomes.
  • the housing 2 includes conical component 13 at the lower end of which there is an opening 14 is located through which the components of the peeled Cereals, namely the cereal grains, the empty husks as well carried dirt and dust for further processing or separation are removed.
  • An electric drive motor is used to drive the throwing disc 7 17 provided that structurally combines with the housing 2 is and is also carried by the support feet 12.
  • a pulley 18 arranged over which one or more V-belts 19 are placed are, which the drive motor 17 with the rotor shaft 6 couple the pulley 9 frictionally.
  • a control device 21 is arranged, which is not only for Commissioning of the peeling system, but also for speed control of the drive motor 17 is used.
