Jenike & Johanson, Westford, Massachusetts, engineering specialists in the handling of bulk solids, has developed successful, application-specific solutions to particle segregation (demixing) occurring during chemical production.
Drawing on the pioneering investigations into the properties of powders and solids conducted by company founder Dr. Andrew Jenike, Jenike & Johanson engineers have devised a unique Tumble Blender and specially-designed Y branches and discharge stations. Through the project-specific adaptation of these and other techniques, specified material blends have been maintained despite even extreme differences in particle size, density or handling characteristics. When asked to supply as well as design specified process equipment, Jenike & Johanson provides written mechanical and performance warranties.
According to Jenike & Johanson Project Engineer Herman Purutyan, "Demixing during processing costs chemical producers dearly in rejected material, inconsistent product quality and inefficient processing." Extra blending is the first cure many try. But as Purutyan notes, this not only limits productivity but can actually cause segregation instead of preventing it. As a result of particle segregation and other solids-handling difficulties, many chemical plants are severely underperforming, he claims.
In addition to its Westford headquarters, Jenike & Johanson maintains offices in San Luis Obispo, California; Etobicoke, Ontario; and Viña del Mar, Chile.
