Another dispersion technique such as media dispersion is necessary to provide adequate force to the agglomerated NPs. Media dispersion. In media dispersion, agglomerated NPs are broken up with the aid of a medium, which is classified as balls or beads, based on sizes of –40 mm and – mm, respectively.

General description. Silver is a good conductor and resistant to oxidation. It is used in printed conductors and printable inks (based on silver nanoparticles). Nanosilver is used as an antibacterial material in filters for air and water purification, in textiles, and for wound treatment.
Developing nanoparticle formulations or poorly soluble drugs. The extent of size reduction is governed by the grinding energy, which is determined by the intrinsic hardness of the drug, grinding media and milling power. The nanoparticulate dispersion was converted into solid intermediates for tabletting by granulating with watersoluble carriers.

Normally for efficient grinding and dispersion, the feed particle size should have a [] (90% of the particles are less than) 1/10 the media size. For example, for 100[micro]m beads, the [] should be about 10 microns (see Table 1).
A patent for a beater cross mill with hinged hammers was granted to H. Currier in Great Britain in 1875. ... specially designed agitator discs mounted symmetrically on a shaft transfer the energy required for wet milling and dispersion to the spherical grinding beads. 1970s.
Depending on your definition of nanoparticles (and nanomaterials in general), the size range where nanoparticles are created does vary. However, the definition given by the European Commission is one that is used in many places of the world and defines nanoparticles which are between 1 and 100 nm is size, where at least 50% of the nanoparticles in a given nanoparticle system/product need to fall into .
Media milling – or grinding – is the most wellestablished manufacturing method for nanoparticle production. Stirred media mills are used in many different industries to reduce particle size, and lithium ion battery manufactures are joining the ranks of those who are able to develop higherquality products because of this equipment.
