Cryogenic Milling

Cold Grinding, Cryogenic Milling

Cold Grinding or Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.

A grinding under liquid and gaseous nitrogen is available on the following plants:

  • Pin Mill
  • Turbo Mill
  • Turbo Mill equipped as a Laboratory Mill

Cryogenic Milling is suitable for the following substances:

  • Tough and elastic materials
  • Products with a high oil or fat content, such as nutmeg, oilseed, spices, flavouring agents
  • Dust-explosive material, as nitrogen or carbon dioxide produces an inert atmosphere by oxygen displacement which safely prevents fires and explosions.

Fields of application for Cold Grinding:

  • Ethylene vinyl acetate (EVA)
  • Food for preservation of vitamins and proteins
  • Spices such as pepper, ginger, cardamom or cloves, for preservation of scents and flavouring agents, aromas, flavors and essential oils
  • Plastics, rubber, thermoplastics, elastomers and waxes
  • Substances with a low softening point
