Vibration is induced by the rotation of a chrome-plated steel ball within ball vibrator housing, which is driven by compressed air (or another inert gas) around a set of hardened steel races within the Vibrator's aluminum or malleable iron cylindrical body. The Speed or Frequency, measured as Vibration-Per-Minute (VPM), is determined by the ball’s RPM. The VPM is adjustable using an air regulator to adjust inlet PSI or an adjustable speed-control exhaust muffler.

Notably, the smaller the ball in the ball vibrators, the higher the VPM at the same PSI air pressure. Higher PSI causes higher VPM. The Centrifugal Force Pounds (lbf) is based on ball size/weight and its RPM: A larger ball or an increase in RPM results in an exponential increase of the centrifugal force produced.

Sizing Guide
Ball Vibrators, when used to prompt material flow, are sized based on the weight and characteristics of the stored material held in the sloped portion of the bin, hopper or other vessel. Generally, for consistent, long term results, select a Ball Vibrator that at 80 PSI (can be run @ 30 to 100 PSI) produces 1-lbf for every 10-lbs of stored material.

Common Applications for Ball Vibrators
Fine, dry materials in small to mid-size bins; Can lines; Chutes & downcomer pipes; Packaging and settling Applications; Moving parts in assembly processes.
