We will address the required operating conditions for a bead mill to grind and disperse particles to less than 200 nanometers and the requirements for grinding large particles to a nanometer range. PARTICLE SIZE CONTROL The particle size achieved from a bead mill is a direct function of the media size used for the grinding process.

The breakage of these aggregates or agglomerates is called dispersing, and thus the stirred media milling of TiO 2 particles can be referred to as dispersing or deagglomeration instead of grinding.
