E&G Associates has developed significant expertise in the application of powder characterization methods to the solution of both product and process development challenges faced by our clients. This led in turn to the formation of iPowder Systems, which serves as a vehicle for instrumentation development for mechanical property measurements of powders as well as commercial sales.

 Evins Mill, Nashville, TN

 Registration closes: November 17, 2014

Powder Flow I:  Measuring Powder Flowability & Its Applications - A Hands-On Design-Oriented Workshop
Nashville, TN • December 8-9, 2014
Registration form
This powder flow workshop should be of interest to those involved in powder and pharmaceutical processing issues for which powder flow properties are critical, including material transfer/handling, segregation, feeding and filling operations, encapsulation, roll pressing and tabletting.  The course is equally of interest to those involved in formulations, bulk drug production, or quality control, who wish to engineer or control powder flow properties to minimize handling problems or improve product quality

Powder Flow II:  Industrial Solids Handling & Mixing- Plant Design Principles & Operation
Nashville, TN • December 10-12, 2014Registration form
By popular request, a new follow-on companion workshop treating industrial applications of the powder flow principles of Powder Flow I and solids mixing, which delves into commonly encountered design & operational issues of powder handling and blending.  Topics include unassisted mass/funnel flow discharge; flow promoting devices such as inserts, aeration and vibration; handling difficult powders; feeders and feed control; mechanical and pneumatic conveying of powders; processing of segregating blends; solids blending & mixing, mixer selection and mixture quality.  This course is useful for anyone optimizing current or designing future solids mixing and handling systems. It presumes a requisite knowledge of powder flow principles such as Powder Handling I, or equivalent experience.

An Introduction to Powder Processing
Nashville, TN • December 8-9, 2014 •Registration form

A new, first powder technology workshop introducing participants to the unique attributes of powders, contrasted to more well understood liquids, and the impact of these complexities on solids processing.  Topics include powder characterization (particle size, moisture sorption, surface area, surface chemistry, hardness, density); segregation & powder sampling; and an overview of key unit operations of mixing, grinding, agglomeration, classification, fluidization, and drying, as well as solids transport between unit operations.   It is valuable to anyone new to powder processing or current practitioners who have not had the opportunity to learn underlying principles of handling and characterizing powders.

Design and Optimization of Granulation & Compaction Processes
 for Enhanced Product Performance

Nashville, TN • December 10-12, 2014Registration form
Course content will include principles of agglomeration; demonstrations of characterization techniques and key agglomeration rate process phenomena; design, scale-up & operation of various granulation processes and compaction techniques (fluid-beds, mixers, pans, tabletting, roll pressing, and extrusion).  Interactions between formulation properties and process equipment are particularly emphasized in the course. Presentations of participant case studies and pre-course characterization of samples are also offered; contact us directly for further details.  This course is based on latest advancements in size-enlargement theory based on the work of Dr. Ennis and colleagues as highlighted in Section 19:Solids-Solids Processing (8th Ed) & Section 20: Size Enlargement (7th Ed) of the Perry's Chemical Engineers' Handbook, “The Science and Engineering of Granulation Processes,” Kluwer Academic Press, 2004, and “Theory of Granulation: An Engineering Perspective,” in Handbook of Pharmaceutical Granulation Technology, 2nd Ed., Marcel Dekker, 2005.
