Besides the direct synthesis of these materials by chemical methods, wet grinding in stirred media mills is a suitable method for the production of sub-micron particles. The main advantage of using wet grinding in stirred media mills over alternative grinding methods is the possibility to apply higher power densities necessary to produce very ...

1.3 Stirred Media Milling 1.3.1 Media Mills Stirred media mills have been in use for over 70 years, Szegvari invented the first mill in 1928. However, media mills did not become popular until the 1950's when they were used as disperser in the pigment and paint industry.42 Stirred media mills come in

Abstract The production of ceramic nano particles in stirred media mills is, due to high grinding media wear and therewith a product contamination as well as high energy requirement and long grinding times not very suitable at the moment. New high-power-density mills and a special modification of the process lead to better economical values for this kind of process.

Wet stirred media milling (WSMM) has been used for the production of nanoparticles of various active agents such as poorly water-soluble drugs, agrochemicals, nutraceuticals, etc. in suspension form as it is a scalable, solvent-free, environmentally benign process. However, the process is energy intensive, costly, time-consuming, and can cause ...

Aug 01, 2005 The control of increasing particle–particle interactions with decreasing particle size plays a crucial role in wet grinding of nanoparticles in stirred media mills. In this contribution it was shown that besides suspension stability parameters like concentration of potential determining ions the operational milling conditions can influence the grinding behavior of nanoparticles in stirred media mills.
