Fundamentals of Powder Flow Technology- Eric Maynard, Senior Consultant, Jenike & Johanson

Handling or processing powders and bulk solids is fraught with problems, whether you are dealing with chemicals, plastics, pharmaceuticals, foods, metals, or a myriad of other materials. This tutorial will provide solid insights into common flow problems that arise when powders and bulk solids are put into silos, bins, and hoppers. Ways to characterize a material's flow properties will be presented along with proven, practical, and cost effective design solutions. Retrofits to existing equipment as well as design of new facilities will be discussed. This topic is critical to all industries in which bulk solids are being handled, processed, or refined because greater emphasis is being placed on process optimization, safety, and cost reductions, all of which are often dependent upon reliable bulk solids handling.

Step-by-Step Process for Designing a Bulk Solid Storage Vessel-Eric Maynard, Senior Consultant, Jenike & Johanson

The procedure for developing a design for a storage vessel for a bulk material is not commonly taught at the university level. Rather, many companies rely upon equipment vendors to provide silo designs for a powder or granular solid. It has been documented in many cases where the silo design was not appropriate for the bulk material to be handled, and as a consequence, costly flow problems have resulted in the solids handling system.
This tutorial will provide a proven, practical step-by-step procedure for designing a bulk storage system fundamentally based upon the measured characteristics of the powder or granular bulk solid. A set of requirements will define the design process, while example flow properties will be utilized to guide the selection of the silo cylinder, hopper, and feeder equipment. This topic is critical to all industries in which bulk solids are being handled, processed, or refined because greater emphasis is being placed on process optimization, safety, and cost reductions, all of which are often dependent upon reliable bulk solids handling
