Mixing and blending of bulk solids is a common processing step in many industries. For example, in pharmaceutical manufacturing of solid dosage formulations (tablets or capsules), small amounts of a powdered active drug are carefully blended with excipients, such as sugar, starch, cellulose, lactose and lubricants. With foods, many powder-form consumer products result from custom mixed batches; consider...

Blending and segregation are two opposite and competing processes in solids handling that ideally fit the expression “two sides of the same coin.” But, if you think about it, coins have three sides and sampling completes the idiomatic expression perfectly. Blending is a necessary and essential process operation widely employed in many industries and materials, from nano-scale powders to...

  Over 1,000 exhibitors from all over the world will fill six halls at the Nuremberg Fairground for Powtech/TechnoPharm 2011 (October 11–13). Held every 18 months, Powtech — the International Trade Fair for Mechanical Processing Technologies and Instrumentation — is the meeting place for representatives of many sectors of the chemical process industries (CPI), including chemicals and...

These days, there seem to be more reasons than ever to change feedstocks throughout the chemical process industries (CPI). Whether environmental, or more directly based on financial and market drivers, big benefits usually require big changes. This is especially true in switching to many renewable feedstocks, which either add or compound challenges related to processing solids. When Columbia Forest...

Portable mixers for pilot plant and small-scale production processing The PB Series pharmaceutical mixers (photo) feature a lightweight frame motor with a right-angle drive, 316 stainless-steel wetted parts, dry running mechanical shaft seal with CIP (clean in place) capabilities and vibration-free operation. Easily tailored to user requirements, the mixers can be configured with shafts up to 48-in. long...

The incorporation of floating solids into liquids is a common challenge throughout the chemical process industries (CPI) in operations ranging from polymerization reactions to fermentation processes and water treatment. Yet, it has received much less attention in comparison to processes involving heavy solids that tend to settle. Both established and recently proven design recommendations for incorporating...

A. Alexander and F. Muzzio, Rutgers University Proper blender selection can improve the mixing of bulk solids. Be sure to consider post-blending segregation problems Mixing and blending of bulk solids occurs frequently in many industrial processes. Though small-scale mixing and blending functions were in use back in the early days of man (for example, mixing flour, salt, yeast and water to make bread)...

Several manufacturing procedures for chemical, cosmetic, pharmaceutical or food products distribute powder-like solids during the liquid or pasty phases of operations. The systems usually used for these operations require the injection of powders in an agitation tank. Dispersion is often performed by the same tool (located on the bottom of the tank) as the one that insures (if required) the emulsion of...

At the Chem Show last month (New York; Oct. 30 – Nov. 1), Resodyn Acoustic Mixers Inc. (Butte, Mont.; demonstrated its new, impeller-free mixing technology, which induces microscale turbulence through the propagation of acoustic waves. Dubbed ResonantAcoustic Mixing (RAM), the now commercially available process promises solutions for many of the complications associated with...
