How to Choose the Right Vibrator for Material Flow Problems
Linear vibrators are best sized by the wall thickness of the bin. The vibrator will clean ≈ 4' to 6' area. It may be necessary to apply several linear vibrators when the entire bin must be cleaned. If the object is to maintain material flow only, fewer vibrators may be used. Use the following guidelines for impacting vibrators:
