  • the longitudinal axis 5 of the shaft 4 is arranged in the vertical direction.
  • the Cutting unit 1 On the shaft 4, six feed knives 6 are offset from one another along the longitudinal axis 5 arranged that they form a kind of spiral. A uniform offset is indicated by a Serrated tooth profile of the shaft 4 and the feed knife 6 ensured. Furthermore, the Cutting unit 1 also has six standing cutting knives 7, which also correspond to the Longitudinal axis 5 are arranged, but all in the same orientation. The feed knife 6 and the cutting blades 7 are arranged alternately.
  • the front, open area of the housing 2 serves the chip feed and is referred to below as the feed area 8.
  • the chips are supplied by means of a screw conveyor (not shown), which is approximately horizontal Direction is arranged and ends just before the cutting unit 1.
  • the feed can For example, something is regulated, especially narrowed, with the help of a baffle may be necessary especially with aluminum chips. Furthermore, the supply of the chips due to only temporary operation and / or a brief backward movement of the screw conveyor be regulated so that blockages can be avoided. To congestion too Corresponding sensors can be avoided (for example, monitoring the power consumption of the drive motor, the speed of the shaft, optical and / or acoustic monitoring) be provided, which reduces the supply of chips or increased load stops. In the rear area of the housing 2 opposite the feed area 8 there is a Sieve plate 9 is arranged, which is used in particular to separate excess liquid.
