Abstract

A method and apparatus for grinding thermoplastic material utilizing a jet and anvil type mill where the particular material to be ground is injected into a chamber against a rotating anvil means while also injecting a liquid into the chamber, the liquid evaporating to cool and embrittle the particles, and then accelerating and re-injecting the particles into the chamber while the liquid continues to be injected for evaporation.
