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.

He is a member of Tau Beta Pi, honorary engineering fraternity and is currently president of Professional Engineering Services, Inc.  

“Jim’s knowledge of the mechanics of screening, based on hundreds of applications, with many different screening methods, make this document a valuable tool for anyone who wants to understand and apply screening to their process,” says Jeff Sullivan, president of Triple/S Dynamics. “One peer reviewer commented he wanted to use it to train his young engineers in the application of screening.”
