Alpine AFS Cutting Mill

Alpine AFS Cutting Mill


The Alpine AFS Cutting Mill uses cutting forces created by a toothed rotor disc for coarse milling of plastics.

  • Designed for coarse milling of soft to medium-hard plastics
  • One-piece grinding discs with a variety of toothing geometries optimized with regard to wear and maintenance.
  • High throughput capacity at low specific energy consumption.
  • Quick and easy access to the grinding chamber

The feed material, usually between 4 and 8 mm in size, is fed into the grinding zone via the intake chute on the mill door. Size reduction takes place between the axially adjustable stator disc and the rotating grinding disc, which rotates at a high peripheral speed in accordance with the shearing and cutting principle. The actual grinding is effected in stages through a grinding gap which tapers from the inside to the outside. The finely ground product exits the grinding zone through an exactly defined gap.

Wherever an exact top-size limitation is required, the mill can be operated in circuit with a suitably designed screening machine. The oversize particles are routed back into the grinding zone. Most types of plastic can be finely ground at ambient temperature using this technology. If, on the other hand, the feed material is heat-sensitive, cryogenic mode is also possible.
