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…
As chemical processors continue to feel the pinch of the worsening economy, particle sizing is becoming an increasingly important issue because it can impact reaction rates and productivity. With the needs of chemical-process-industries (CPI) customers in mind, manufacturers of a…
Accuracy and reliability, ease of use, the ability to handle special materials and compactness are all factors to consider when purchasing weighing, proportioning and feeding equipment for use in the chemical process industries (CPI). Because each CPI application differs, there’s…
Learn what causes caking and how testing methods can help identify critical parameters for controlling it Caking occurs when an easy-flowing powder becomes cohesive after storage or transport, forming agglomerates comprised of individual particles that are bonded together. As a…
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…
TubeMaster, Inc. (Louisville, Ky.; edlinks.chemengonline.com/7373-547) has filed U.S. and foreign patents for Dog-leg — claimed to be the world’s first articulating catalyst-loading device that permits loading of single and multi-layer catalyst to any height or outage, regardless of reactor vertical-head…
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…
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…
Convey tough bulk materials that tend to pack, cake, smear, break apart or fluidize, and prevent separation of blended products Flexible screw conveyors are suitable for use with most bulk materials, from sub-micron powders to large pellets, both free-flowing and…
An automated and precise powder dispenser Intended for distributing resins from reservoirs into reactors, reaction blocks, and microplates, The REDI automated powder-dispensing platform (photo) is available in several configurations. These include: the REDI super, which distributes powder samples from 100…
