Mini with high performance - processing of the smallest sprues

The small, compact Hellweg 80 series of beside-the-machine granulators are used directly mounted on the frame of an injection moulding machine or beside-the-machine. There they grind, among others, sprues arising from small to very smallest components and products in so-called micro injection moulding of, for example, mobile phones in telecommunications, or medical products such as syringes, drain tubes, etc.

Other application fields are the laboratory area and model construction.

The benefits:

  • slow running granulator (280 rpm)
  • ideal granulate quality with very low dust
  • co-rotating rotor discs prevents material
  • trapping between rotor and housing
  • special sieves guarantee constant grain size
  • quick sieve and knife change
  • no need to adjust the rotor knife
  • knives can be reground several times
  • external bearing, dust resistant
  • basin with connector for suction
  • almost maintenance-free
  • easy and fast handling
  • opening without tools
  • CE certified
