GENERAL DESCRIPTION AND ACCESSORIES Pneumatic knockers from singold • World's most powerful knockers • Greatest possible impact effect • Lowest own weight • Reliably remove product residues, caking, as well as shaft and bridge formation in containers and silos

Pneumatic singold-knocker – General information 1 The pneumatic singold knocker is used on bulk solids with material flow disturbances such as bridging and rest formation when high speed vibrators or shakers with soft sinusoidal oscillations are not effective. singold-knockers achieve the greatest possible impact effect with the lowest possible weight. The effect of the knocker is comparable to the effect of the infamous "silo hammer", without having dented silo spouts making the material flow even more difficult. The effectiveness of the knocker is evaluated with the following rule: If the...

4 Technical data pneumatic singold-knocker type K: Type *1 The internal stroke describes the distance covered by the magnetic impact piston, i.e. the acceleration distance until it hits the striker bolt. *2 The impact equivalent weight, often also called impact force, corresponds to the effect of the weight specified here, which falls from a height of one meter. The knocker is controlled by an electrical control with a 3/2-way solenoid valve. It requires a working time for the function (pressurized) and a pause time for returning to the initial position (exhausted). Working time is the time...
