Webinar: How to Choose Between a Rotary Valve and Screw Feeder
Eric Maynard, vice president, Jenike & Johanson

Both the rotary valve airlock and the screw can be effective feeders for bulk solids. However, there are subtle differences in their operation and integration with the hopper design that could upset flow and performance if not addressed. This webinar will discuss features of each type of feeder and provide critical design tips to help you to avoid common design and operational problems.  

On Wednesday, September 18, 2019 at 2pm Eastern/11am Pacific, Eric Maynard, vice president, Jenike & Johanson, will present “How to Choose Between a Rotary Valve and Screw Feeder” as part of Powder & Bulk Solids’ DryPro webinar series.

Maynard received his B.S. in Mechanical Engineering from Villanova University and his M.S. in Mechanical Engineering from Worcester Polytechnic Institute. During his 23 years at Jenike & Johanson, he has designed handling systems for bulk solids including cement, coal, limestone, plastic powder, food products, and pharmaceuticals. He is the cement industry specialist at Jenike & Johanson, as well as the technical specialist for dust explosions and powder electrostatic behavior. He routinely lectures on the storage, flow, and pneumatic conveying of bulk solids for the American Institute of Chemical Engineers (AIChE) continuing education series, private companies, in-house courses, and the Powder & Bulk Solids Conference).
