Micronization and nanoparticle production of poorly water-soluble drugs was investigated using single wet milling equipment operating in the attritor and stirred media modes. The drug particles in the median size range of 0.2?2??m were prepared by changing the milling mode and operating conditions of a Micros mill with a purpose of elucidating ...

Grinding behavior of nanoparticles in an attritor mill and the minimum achievable particle size are strongly influenced by the suspension stability. In the present work, suspension stability (i.e. ζ-potential) of nanoparticles was studied by measuring pH as a function of grinding time in the wet milling process. It was found that after a ...

On the other hand, the attritor mills can process higher quantities of powders (between 100 g and 10 kg) and takes several hours for the large scale production of nanoparticles in commer-cial premises [22]. Tumbler mills are more economi-cal than the high energy ball mills for the large scale synthesis [23]. On the other hand, vibration mills

New Developments in Attritors. The attritor, or stirred ball mill, is a grinding mill containing internally agitated media. There are quite a few types of attritors; they can be categorized as dry grind, wet grind, regular speed (to 400 rpm) and high speed (400–1,800 rpm) attritors. A useful and simple equation describing the grinding ...
