Ball Vibrators

RTI S.r.l.’s ball vibrators generate thrust via a ball that, driven by compressed air, rolls along two tracks made of heat-treated steel. Due to the friction—albeit of the rolling type—between the metal parts, it is recommended to use lubricated air in order to extend the vibrator’s service life and reduce wear.

Lubrication is not, however, mandatory: ball vibrators can also operate in dry or partially contaminated air. Under these conditions, however, mechanical wear increases and noise levels rise over time.

From a design perspective, the sphere has a less favorable geometry than the turbine when it comes to receiving airflow. Furthermore, the gap between the sphere and the vibrator body allows a greater volume of air to pass through. Consequently, overall efficiency is lower, with higher air consumption and noise levels. On the other hand, ball vibrators allow for higher average vibration frequencies.

Typical applications for these models include the handling of small parts, such as fasteners and small components, the unloading of small hoppers, and use in screening systems, where rapid and effective vibrations are required.
