The Attritor is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2"
What is the Difference Between Attritor Mill and Ball Mill?
Another difference between ball mills and attritor mills is the milling atmosphere. In ball mills, the materials to be ground are placed in a container that is filled with air or an inert gas.

Silicon powder (99.99 %, particle size 0.05mm) was ball-milled in an attritor ball-mill at 400 rpm for 30 h in hexane. It was found that slurry of ball-milled silicon in hexane was produced as a result of the milling. This slurry was sprayed into a silica tube at high temperature (800±1100℃) under an argon atmosphere.
