material flow solutions
The original: The world’s first and most powerful pneumatic knocker was developed at singold gerätetechnik gmbh. For over 50 years, singold knockers have been ensuring optimum material flow in the building materials, chemical and food industries and in many other areas of application.
Another ingenious invention of the singold engineers is the flap shutter for the complete emptying of containers and silos. In specialist circles, it is affectionately known as the “singold flap”.
singold gerätetechnik stands for expertise and experience in material flow solutions and is produced exclusively in Germany – 100% Made in Germany quality. From expert technical advice to top products and customised special designs, you get everything from a single source!
The Pneumatic Knocker is used for bulk goods with material flow problems for instance bridge, siphon and residue formations, when high speed shakers and vibrators with soft sine-shaped oscillations are no longer effective.

The Pneumatic Distance-Knocker QJ is suitable for knocking against slow-moving drums and filling or emptying stations with moving containers.

Choose the right knocker for your application
We have two types of knockers in our range: our classic ‘singold’ Pneumatic Knocker Type K is suitable for many applications in which the knocker is attached to the silo wall. The special developed Pneumatic Distance-Knocker Type QJ is suitable for knocking from a distance against slow-moving drums and filling or emptying stations with moving containers.
The singold flap closure is suitable for all conceivable bulk materials and solid-liquid mixtures if the container is emptied completely.
Double Flap Sluice
The Double Flap Sluice are used when bulk materials are conveyed to a different pressure level, are fed and discharged in batches or are fed into other processes or plants in batches.
Cellular Wheel Sluice
Cellular Wheel Sluice are installed below silos and bunkers to relieve the silo pressure from the bulk material and to relieve downstream discharge devices such as screws, troughed chain conveyors, tube chain conveyors or discharging weighfeeders etc.
