Blast Rotor Mill 

A blast rotor univesal mill has the following general features:
  • feeds ranging from brittle to elastic, including most of the materials handled by the other grinding tools
  • handles feeds that are slightly abrasive (such as limestone containing minor abrasive component)
  • temperature-sensitive feeds (such as resins and powder paints)
  • can achieve a final average particle size of less than about 40 microns
  • consists of several rigid, replaceable bars or blades mounted inside a pair of rings
  • operates like a turbine, generating a large volume of airflow during grinding and quickly dissipating the grinding heat
  • mounted inside a screen or combination stator
  • the final average particle size can be controlled by adjusting the tool's peripheral speed and choosing a particular stator
