Rotary ball vibrators for fine powders and granular materials
Ideal for preventing material build-up and blockages, these rotary ball vibrators enhance the flow and compaction of fine powders and granular substances across various production processes.

Compacts and Vibrates Fine Powders and Granular Materials
The Rotary Ball Vibrators S-series from WAMGROUP offers a highly efficient solution for precise vibration and compaction tasks. Using a ball in an eccentric guide, these vibrators produce low amplitude, high frequency vibration, perfect for managing fine powders and granular materials such as sand, seeds, and chemical products. Available in eight different sizes, the S-series operates on an air pressure range of 2 to 6 bar (29 ~ 87 PSI) and is compliant with ATEX EX II 2DG cT(x), ensuring safe usage in explosive environments. Its robust design—featuring a blue aluminum body and galvanized steel cover—ensures durability in demanding conditions. With operating noise levels reaching 90 dB(A) and low air consumption, it’s an economical choice for continuous and manual operations in sectors ranging from construction to pharmaceuticals. Versatile in application, the S-series ensures efficient handling of end-products like talcum powder, granular fertilizer, PET pellets, and more.
