Agitated Media Mills are media mills that employ an agitated (or stirred) grinding media action for grinding of the ultrafine particles. Many types of metallic or ceramic grinding media are available for the fine grinding of a particular mineral, metal or chemical power. ... They are dry airswept media mill used for the production of fine ...
The drive sets these balls in motion and the ground material is crushed between the balls. In agitated media mills, the balls are set in motion by an agitator. The PULVIS is suitable for ultra-fine materials and can achieve fineness levels of up to d 97 <1μm. Additional agitated media mills include the ATR (dry milling) and the ANR (wet milling).
