Rotary roller vibrators for material flow assistance
Enhance material flow efficiency in your production line with high-frequency, low-amplitude vibration technology—ideal for demanding environments such as concrete consolidation and precise hopper emptying, ensuring optimal performance where consistent material handling is crucial.

The OR-series Rotary Roller Vibrators from WAMGROUP are integral for industries requiring precise material flow and compaction solutions. These vibrators generate low amplitude and high frequency vibrations through rollers moving inside an eccentric guide, providing more force than traditional ball-type options. Ideal for applications such as concrete consolidation, foundry moulds, and hopper emptying, they support diverse end-products including concrete blocks, foundry castings, and animal feed pellets. Operating within 2 to 6 bar (29 ~ 87 PSI), they are suited for explosive environments, achieving compliance with ATEX EX II 2DG cT(x). The vibrators are available in various sizes, each equipped with a durable aluminum casing and brass cover, ensuring reliability under high-temperature conditions. Integration is seamless, supporting continuous operations with easy installation. With operating noise levels of 90 dB(A), these can be incorporated into existing lines with minimal disruption.
