Triple/S Dynamics has just released “Screening Theory and Practice." This 54-page technical paper written by James F. Sullivan, former President and Chairman of Triple/S Dynamics, distills his 55 years of experience in the design, development, manufacture and sale of bulk granular material handling and classifying equipment. Mr. Sullivan discusses the principles underlying the performance, design and application of mechanical equipment for particle separation by screening. Mr. Sullivan holds a BME with distinction from the University of Minnesota, 1947. He is a member of Tau Beta Pi, honorary engineering fraternity and is currently President of Professional Engineering Services, Inc.
