Jenike & Johanson marks 60 years leading bulk solids handling. They apply science-based engineering to solve complex storage, feeding, conveying, and processing challenges for reliable operations. TYNGSBORO, MA - Jenike & Johanson is celebrating its 60th anniversary, marking six decades of engineering innovation, scientific leadership, and problem-solving in bulk solids handling. Since its founding in 1966 by Dr. Andrew Jenike, the company has helped transform bulk solids handling from a largely trial-and-error discipline into a field grounded in material testing, flow science, and proven engineering principles. Today, Jenike & Johanson continues to apply that foundation to some of the most complex storage, feeding, conveying, and processing challenges faced by industry. For 60 years, the company has partnered with manufacturers, processors, equipment suppliers, and engineering organizations around the world to improve the reliability, safety, and performance of bulk material handling systems. Its engineers work across industries including mining, chemicals, food, pharmaceuticals, energy, cement, biomass, and advanced materials. “Reaching our 60th anniversary…

Dr. John Carson has published a new biography detailing the extraordinary life and technical breakthroughs of Dr. Andrew Jenike, the founding engineer behind the modern science of bulk solids storage and flow. Jenike & Johanson is pleased to announce that Dr. John Carson, President Emeritus of Jenike & Johanson, has published a new book titled Andrew Jenike: Founding Father of the Science of Bulk Solids Storage and Flow. The book explores the life and contributions of Dr. Andrew Jenike, widely recognized as the founding figure in the science of bulk solids storage and flow. The Breakthrough in Bulk Solids Design On April 16, 1953, Dr. Jenike made a pivotal decision to dedicate his work to solving one of industry’s most persistent challenges: understanding and predicting the flow behavior of bulk solids. His research established the fundamental principles that continue to guide the design of hoppers, silos, feeders, and material handling systems across industries. From Wartime Poland to Engineering History Dr. Jenike’s work introduced key concepts such as mass flow and funnel flow, flow/no-flow criteria, and methods for calculating wall angles and outlet dimensions—approaches…
