On Thursday, February 18, 2021 at 2 p.m. Eastern/11 a.m. Pacific, Dr. Kerry Johanson, chief operations officer for Material Flow Solutions Inc., will present "Understanding and Controlling Size Reduction in Processing or Milling – a Mechanistic View" as part of Powder & Bulk Solids' DryPro webinar series.
The breakage of particles during processing or packing leads to customer complaints and sometimes products that cannot accomplish their designed purpose. Likewise, placing a particular material into a specific mill sometimes leads to unexpected results in terms of particle size control. This webinar will address controlling breakage of material in processes, including milling.
When we understand what causes a particular material to break and how it breaks, we can use that knowledge to understand/predict how a particular material might behave in a mill or other prescribed process. In the case of the process, we want to design that process to limit breakage. In the case of milling, we want to design or chose the mill that can create material with a prescribed size distribution.
Johanson began his career in powder flow and material handling as a summer lab technician with Jenike & Johanson in Billerica, MA during his high school and undergraduate years. After receiving his BS in 1985, he spent 14 years with JR Johanson Inc. in San Luis Obispo, CA, finally serving as their chief technical officer. He received his Ph.D. in chemical engineering from Brigham Young University in 1994, and in 2000, he branched out and moved to Florida, where he divides his time researching at the University of Florida Particle Engineering Research Center and serving as the chief operations officer for Material Flow Solutions Inc., the consulting firm he founded in 2001.
Johanson has authored 40+ technical papers which have been published in numerous technical journals internationally. He has developed a course for teaching powder flow and technology to graduate students and mentored five doctoral graduates at the University of Florida. Johanson has presented numerous industry seminars on the topic of powder flow in industrial applications.
Johanson holds PE licenses in both Florida and Utah and is an active member of AAPS, AIChE, ASME, ASTM, and IChemE.
