DISPERSING for Liquids & Powders
Dispersion is usually defined as the mixing of two or more non-miscible liquids, or solids and liquids, into a pseudo-homogeneous mass which is more or less stable as measured by its life before noticeable separation occurs. A high speed flat shearing blade is most often used moving at tip speeds of 4500-6000 fpm in order to achieve homogenizing, deagglomeration and/or particle size reduction. This can cover a wide range product types from low viscosity slurries to heavy dispersions such as pigment pastes, caulking compounds or dilatant products. Power input per unit volume can vary widely. -Dispersing can be a process unto itself or a step prior to fine grinding. It is critical to ensure that the process be completed based on the desired results which will depend upon many factors reviewed below
