What makes it special? The flap swings completely out of the product flow to the side, ensuring no wear occurs on the flap itself. The singold Flap Shutter is a true masterpiece of engineering, standing out with its exceptional robustness and durability. What makes it special? The flap swings completely out of the product flow to the side, ensuring no wear occurs on the flap itself. All bearings and joints are located outside the product flow, making them virtually maintenance-free. Thanks to the sophisticated mechanics, the seal experiences no friction or shearing forces. Additionally, the bulk material remains undamaged and unaltered. [IMG06**M80**Style] Handles tough working conditions with ease This makes the flap shutter significantly advantageous for highly abrasive bulk materials compared to rotary and pendulum flaps or sliders. Some singold Flap Shutters have been in operation for several decades and still perform their tasks reliably to this day. It’s no surprise, then, that all major glass plant manufacturers, for example, rely on singold’s proven Flap Shutter. [IMG03**M60**Style]

Pneumatic Knockers pose a simple but effective approach, just like a hand hammer can get the bulk material flowing again, the Pneumatic Knocker will do the same. Shakers, vibrators, knockers – there are many solutions for free material flow in the bulk goods industry. Yet, finding the right one can sometimes feel more complicated than necessary. singold gerätetechnik gmbh, manufacturer of the world’s first and, therefore, original pneumatic knocker, has a simple but all the more effective approach: whenever a hand hammer can get the bulk material flowing again, the pneumatic knocker will do the same. However, it has significantly more power, requires no human effort and does not dent the silo. The pneumatic knocker was first developed over 50 years ago by company founder Erwin Lüer, and to this day, singold’s pneumatic knockers remain the most powerful on the market. They operate only when needed, minimizing strain on weld seams that can otherwise fatigue under continuous vibration. By activating as required, the pneumatic knocker protects containers, reduces compressed air consumption, and lowers noise levels, contributing

Problems with flow? Bridging, funnel flow, stagnant zones can be counteracted with a pneumatic knocker, when vibration is not enough. The pneumatic knocker is used for bulk goods with material flow problems for instance bridging, funnel flow 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 additionally 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 E = m/2 × v2 [kgm/s2 = Nm] and as impulse J = m × v [kgm/s = Ns]. There is no impact force or out-of-balance

Distance-Knocker QJ - installed at a distance from the object to be knocked off Distance-knocker QJ from singold: Engineering at its very best The pneumatic distance knocker from singold gerätetechnik gmbh is a unique product and the result of the highest level of engineering - well thought out down to the smallest detail. It was developed by the company’s founder Erwin Lüer, whose pneumatic knockers remain the most powerful on the market today. Mode of action The distance-knocker QJ is based on the simple, yet ingenious idea of the pneumatic knocker. Spontaneously released energy stored in the form of compressed air, accelerates the percussion piston, which is designed as a permanent magnet. The piston hits a mobile impulse part, which is strongly accelerated after the impulse set and transfers the energy to the element to be knocked off. This process occurs at such a high speed that it is barely visible to the human eye. Due to its additional impulse part, the distance-knocker QJ broadens the application possibilities when compared

Singold introduces a flap shutter, a further development of the pendulum flap. It can be used for the complete unloading of containers and bulk material of all kinds. The flap shutter from singold gerätetechnik gmbh is an advanced version of the conventional pendulum flap. The flap shutter is used for the complete unloading of containers and bulk material of all kinds. Examples include hopper scales, primary and secondary vessels in mixing plants, wagons, reservoirs under filters and separators and cone worm mixers. Sophisticated mechanics The flap shutter from singold gerätetechnik gmbh was developed with the highest level of engineering. Thanks to its ingenious mechanics, the flap shutter first moves vertically downwards and then quickly swings completely to the side out of the product flow. This minimizes wear, especially with abrasive materials. The bulk material is neither damaged nor modified, nor is there wear on the flap shutter. This and its lubrication-free slide bearings make the flap shutter from singold an extremely enduring and low-maintenance device. Even with manually operated designs, large nominal widths with
