SCUA Pneumatic Knockers provide elastic shocks to the sides of bins and hoppers, ideal for preventing material from settling. Bridging, siphons and residue formation usually occur at or near the actual discharge points. Depending on size and configuration of the bin, chute or silo, a number of knockers could be fitted at trouble spots. Simply put, if the material may be brought to flow by use of a hammer, Pneumatic Knockers would be an effective option.
The Pneumatic Knocker is highly versatile as the percussion rate can be varied to suit a given application through adjusting the air flow/pressure from the control panel. Available in three sizes (40mm, 70mm and 100mm piston) Pneumatic Knockers can generally be used to achieve the desired result when high speed shakers and vibrators with soft sine shaped oscillation are no longer effective.
