About us
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!

singold Pneumatic Knocker
MAXIMUM IMPACT EFFECT WITH THE LOWEST WEIGHT 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 effect of the knocker is comparable to that of the famous “silo hammer”, but without distorted silo spouts impeding the material flow. The knocker is normally controlled by an electrical control system with a solenoid valve. Within the area where the knocking takes place there should be enough space for the impact to expand in all directions. Reinforcements of the silo walls and additional ribs should be avoided, as this increases the weight and the strength of the silo walls and thus reduces the effect of the knocker. The Pneumatic Knocker produces an ideal elastic shock that is specified as the impact energy [Nm] and as impulse [Ns]. There is no impact force or imbalance such as vibrators generate. The effectiveness of the knocker is evaluated according to the following rule: IF THE PRODUCT CAN BE KNOCKED OFF OR MADE TO FLOW WITH A HAND HAMMER, THE PNEUMATIC KNOCKER IS ALSO EFFECTIVE.
singold Flap Closure
The “singold” Flap Shutter is used for all kinds of bulk material and solid-liquid mixtures, when the container is to be completely emptied. Examples: Container scales, container, primary and secondary vessels in mixing plants, wagons, reservoirs under filters and separators, cone worm mixers By means of the lever system, the flap is vertically moved down and swivelled laterally by the side of the discharge opening, thus enabling a free discharge of the product. Joints and bearings are situated outside the product stream, their standard execution is service-free (until approx. 200 degrees C). The pneumatic design allows the flap quick opening, so that the product stream is not deviated. Also in case of manually operated flap designs, large nominal widths can be opened quickly with low energy consumption at a high flap load. The Flap Shutter is available in different designs, materials and compressive strength.
