James Swindlehurst, Primasonics, UK, explains how acoustic cleaners can help maintain maximum continuous material flow in many industrial processes including silos and hoppers.
A
coustic cleaners are widely employed wherever ash, dust, and powders are generated, processed, stored, or transported. Primasonics acoustic cleaning systems ranging from 60 - 420 Hz in fundamental frequency have been beneficial in both preventing material hang-ups and maintaining maximum continuous material flow in a range of industrial processes including silos and hoppers. Indeed, some of Primasonics’ most challenging but successful applications have been within silos which
contained dry materials such as cement, carbon black, and fly ash, to name a few common examples. It is important to understand several main advantages that acoustic cleaners have over the alternative cleaning and material handling methods which have been employed to try and aid material flow. Primasonics’ acoustic cleaners operate at fundamental frequencies much higher than the natural frequency of the silo construction, thus
