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
