Rotary ball vibrators for bulk solids discharging
In many industries, fine powders or granular materials such as sand or seeds often present flow issues in silos, hoppers, or bins. These materials may become compacted, impeding smooth discharge and causing operational inefficiencies.

Generate low amplitude, high frequency vibration
The S-series Ball Vibrators by WAMGROUP generate vibration through the movement of a ball inside an eccentric guide, producing low amplitude, high frequency vibration. These vibrators are particularly effective for fine powders and granular materials, aiding in the smooth discharge in bulk handling. Constructed from durable blue aluminium with a galvanized steel cover, the S-series is available in eight different sizes. They operate with a working pressure range of 2 to 6 bar (29-87 PSI) of oiled air, making them energy-efficient. Additionally, they are compliant with ATEX EX II 2DG cT(x) standards, suitable for explosive environments. Their operating noise level reaches 90 dB(A), and they are the most economical solution among pneumatic rotary vibrators.
