Preventing Particle Segregation and Its Harmful Effect on Product Quality-Eric Maynard, Senior Consultant, Jenike & Johanson

Maintaining a uniform blend of dry bulk solids is a problem faced daily by engineers and operators in industries as varied as chemicals, pharmaceuticals, foods, plastics, and battery production. Even if a "good" blend is achieved, often the major problem is how to maintain that blend through downstream powder handling in equipment. The inability of maintain a blend (i.e. segregation) at the point where it is needed, is always costly in terms of rejected material, extra blending time, and defective end products. This topic is important to industry because once the mechanisms of segregation are understood, they can be used to analyze existing problems and to ensure design techniques are applied to prevent problems.

Mixing, Blending, and Sampling of Bulk Solids-Eric Maynard, Senior Consultant, Jenike & Johanson

Obtaining a uniform blend of dry bulk solids is a common problem in many industries, especially pharmaceuticals, foods, chemicals. Poor blending, or the inability of maintain a blend (i.e. segregation) at the point where it is needed, is always costly in terms of rejected material, extra blending time, and defective end products. This topic is important to industry because once the mechanisms of blending are understood, they can be used to properly select blending equipment. In addition, particle sampling techniques are discussed.
