Eriez has released a new educational video providing an overview of best practices for designing hopper transitions in vibratory feeding and conveying systems. The video is intended to assist engineers and operators in achieving more reliable and consistent bulk material handling performance by focusing on transition geometry and its influence on material flow.

Hopper transitions, which connect bulk storage hoppers to vibratory feeders, play a critical role in how material is delivered onto the feeder tray. The video explains how specific design choices can affect flow behaviour, discharge rates, and the mechanical load imposed on feeding equipment.

Among the topics addressed are the effects of hopper wall angles, throat size, and the overall shape of the transition section. The video highlights how steeper wall angles and properly sized throat openings generally promote better flow, while flat or vertical walls and oversized throats may contribute to issues such as material buildup or erratic flow patterns. These problems can, in turn, affect the feeder’s performance and lifespan.

“Minor deviations in transition design can result in inconsistent material flow or increased loading on the feeder,” notes Clay O’Dana, Global Product Manager – Vibratory at Eriez. “This can complicate equipment sizing and reduce operating efficiency over time.”

The video also discusses the importance of accounting for material characteristics—such as cohesiveness, particle size, and bulk density—when designing a transition. Since these properties vary significantly across applications, the video emphasizes that hopper transition design should be approached on a case-by-case basis.

In addition to highlighting common design flaws, the video offers a range of practical suggestions for improving system performance. These include ensuring smooth internal surfaces, maintaining appropriate discharge clearance, and avoiding abrupt geometry changes that may disrupt material flow.

The resource is intended for use by plant engineers, maintenance teams, and equipment designers involved in the handling of bulk solids using vibratory technology.
