Our wide range of variants: The ideal knocker for every system

Just as the application scenarios for pneumatic knockers are diverse, so too are the requirements. Whether high temperatures, special hygiene requirements or very large silos, singold gerätetechnik gmbh offers a wide range of pneumatic knockers so you’ll have no problem finding one perfectly suited to your specific needs.

Application temperature is crucial

The most important factor in selecting the optimum knocker is the application temperature. For temperatures up to 60 °C, a standard version with a plastic piston can be used. For applications above 60 °C, the piston is made of aluminium. Cover and anchor plate, tube and striker are made of aluminium, steel or stainless steel, depending on the individual application situation.

The pneumatic knocker can even be used with wall temperatures of over 140 °C. A T-shaped welding plate to increase the distance to the hot wall, a heat-dissipating plate and a heat insulation plate are available as accessories in this case.

Steel or stainless steel for special challenges

Even if the application temperature is below 60 °C, steel knocker models may still be the most suitable due to their resistance and durability. This applies to working areas with aggressive types of dust or vapours, such as the fertiliser industry, or if the knocker is to be used on different containers.

For plants with increased hygiene requirements, singold gerätetechnik gmbh produces knockers in which all external parts are made of stainless steel.

When direct mounting is not possible: Distance knockers

If a classic pneumatic knocker cannot be mounted due to movement or high temperatures, the Pneu­matic Distance-Knocker QJ is an alternative. Depending on the size, it bridges a distance of 25-35 mm to a container or a rotary drum. This makes it ideal for filling and emptying stations with changing containers, slowly rotating drums and hot walls. The piston rod is available without thread, with external thread and with internal thread, as well as in an extended version, allowing the distance of the knocker to be selected as high as possible for high-temperature walls. Versions free from non-ferrous metal are available for the metallurgical industry. ((Evtl. Link zum QJ-Text))

Models to improve sound insulation

To improve occupational safety, models with strikers made of the rubber-elastic material Vulkollan are available. In addition, noise emissions can be reduced with special noise protection hoods.

Special designs according to customer requirements

The experts at singold gerätetechnik gmbh will be happy to assist you in selecting the optimal knocker model for the respective application situation. In addition, our engineers are happy to respond to other customer requests in a flexible manner. Special designs are also possible.

 

Overview

K160: The Most Powerful Pneumatic Knocker in the World

singold gerätetechnik gmbh produces and sells the world’s most powerful pneumatic knocker. While competitor models can at best cover a wall thickness of up to 12 mm, the K160 can knock walls with a thickness of up to 25 mm. This makes it suitable for massive, heavy-duty containers. For example, it is used in the mining industry for discharge chutes, in the building materials industry for gravel bunker outlets, in the chemical industry for mixing plants, in the lime industry for silos with a capacity of over 200 tons and in the fertilizer industry .

 

Supernatural Strength

The powerful model has an impact energy of 423 newton meters. This corresponds to the energy generated when a weight of 42.3 kg is dropped from a height of 1 meter. This high impact energy cannot be achieved with human forces, even if a 20 kg sledgehammer were used. The reason? The acceleration and, consequently, the final velocity of the impact weight in the knocker is far higher than the final velocity that a human being can generate. When the piston, which is designed as a magnet, is pulled off the anchor plate, the acceleration in the K160 pneumatic knocker is about 25 g = 250 m / s². When the magnet hits the striker at a speed of about 7 m / s, accelerations of up to 3000 g = 30,000 m / s² occur. This is one of the fastest values ​​in applied technology. Due to the lower acceleration,

 

Knocking at the Limits of Technology

The pneumatic knockers from singold gerätetechnik gmbh are true masterpieces in the art of engineering: they create the greatest possible impact with the lowest possible dead weight, thereby testing the limits of technology. The K160 model weighs 62 kg and has compact external dimensions, meaning the knocker can easily be retrofitted into existing plants.

The sophisticated design of our pneumatic knocker could even enable the engineers at singold gerätetechnik gmbh to produce more powerful models than the K160, which could knock walls with a thickness of over 25 mm. However, there is a lack of possible applications for such potent knockers.

 

The Right Knocker for Every Plant

singold gerätetechnik gmbh offers a variety of other knockers in addition to the world’s most powerful one. Depending on the operating temperature, application area and wall thickness, a different model is optimally suited in each case. Our experts will be happy to advise you with their extensive knowledge in order to find the best individual solution to avoid problems in material flow.

New Sales Base in England with Powder Process Design Services

singold gerätetechnik gmbh has a new sales base for Great Britain and Ireland. Powder Process Design Services is now the point of contact for customers in the region.

The continuing expansion of singold gerätetechnik as a manufacturer of pneumatic knockers and flap locks led to the decision to provide customers in Great Britain and Ireland with a personal contact on site.

Powder Process Design Services was chosen for a good reason: “The company is specialized in plant engineering and process technology and has installed our knockers in the past,” explains the operation manager of singold gerätetechnik, Oliver Lüer. “Therefore, our contact person, Bradley Thomas, is familiar with and has an appreciation for our products.”

singold gerätetechnik worldwide

Powder Process Design Services compliments the network of singold gerätetechnik’s worldwide sales force. Additional business partners can be found internationally in Australia, Israel, Sweden, South Africa, and Switzerland.

Flap shutter from singold: lightning fast, enduring, low-maintenance

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 a high flap load can be opened quickly with little physical effort. Erwin Lüer, the company founder, applied for the patent of this innovative design in the 1970s.

Custom-made solutions for every application

The flap shutter is available in different materials, designs, and closing forces. Therefore, it can be used everywhere, where there is a need for shredding, sifting, drying, grinding, or sorting. The range of applications is enormous: from waste sorting and waste incineration to the mining of salt, bromine, lithium and titanium to the production of wood fibers or fertilizers. The flap shutter has achieved particular importance in the glass industry, for example in Zippe’s recycling and batch plants.

If two flap shutters are arranged one above the other, a double flap shutter is obtained. This is helpful when bulk materials are conveyed to a different pressure level, for example when discharging from cyclones.

 The closing force of the flap shutter can hold up to a 5 m water column. A special version is available for use at high temperatures (up to 350 °C).

We are happy to advise you on the selection of the ideal version for your company.
