Grinding and dispersing with stirred media mills (Fig.) represent important process steps in many branches of industry. The course gives an overview about the physical phenomena of grinding and dispersing in stirred media mills, and shows how this knowledge can be used for the design and optimization of grinding and dispersing processes.
Bead Mills That Offer Nanotechnology. Bead mills are grinding and dispersing machines designed to grind and/or disperse particles down to the micro and nano scales. Beads (grinding media) inside the grinding chamber are agitated by rotating the shaft and the particles are ground and/or dispersed by the collision and shear force of the beads.
A grinding process for forming a slurry of nanoparticles, consists of the following steps: forming a mixture by mixing a matrix, a dispersant and dispersing media together; adding a pre-treated grinding-media into the mixture; wherein the grinding-media are glass beads with an average particle diameter of less than 100 m; milling or grinding the mixture; and separating the grinding-media from ...
Over the past few years we have observed an increase in the desire to use bead mills for grinding and dispersion of "nanoscale" particles. The objective of this paper is a general discussion of how this process works in a bead mill, the parameters required to successfully produce these nanoscale dispersions, and some experience in grinding or particle size reduction of solids to the nanoscale.

nanoparticles: one is known as "bottom-up" and the other is called "top-down." Bottom-up processes may begin with either a gas or a liquid, and the desired particles are extracted or fabricated by means of evaporation, precipitation, or the action of various solvents. The top-down process consists of grinding or dispersing solids or
