2009-5-3  Mixing of powders is a common operation in any industry. Most powders are known to be cohesive, many agglomerate spontaneously when exposed to humid atmosphere or elevated storage temperature. Agitation of the powder (especially powders with different bulk densities) may result in migration of smaller particles downwards and of larger ones upwards. Another problem is segregation

CiteSeerX — Mixing of solids in different mixing devices

In this paper, static mixers, as devices for powder mixing, are tested as well as Turbula and V-shaped drum mixer, since those devices are commonly used for powder blending in industry. Mixtures that were blended by means of those three devices were made out of the model material, quartz sand, in different component ratios (20:80 and 30:70).

Mixing is completed using some form of impeller or mixing element such as paddles or blades. Shearing mixing is a high speed process that is part of the convection group. The shearing process involves the rapid movement of an impeller that shears, disperses, pulverizes, and greatly impacts materials such that they become smoother and mix easier.
