Recycling and crushing technology
BHS-Sonthofen will unveil the new Universal Shredder of type NGU at IFAT 2016. This new product extends the company”s range of single-shaft shredders by a machine designed for conventional recycling facilities and use in the manufacturing industry. It is generally suitable for all materials that can be cut and is characterized by a sturdy design, easy operation and high availability. The new Universal Shredder is available in several versions – for example with a screen perforation of 30 mm – for a throughput of 6.5 t/h and more.
The new Universal Shredder of type NGU shreds the loaded material to a size between 20 and 100 mm. It can be used at conventional recyclers for shredding various materials, for example, for cutting paper and paper rolls, for destroying files and data media, as well as for almost all plastic parts, leather and textiles, residual wood, cables or parts made from PET.
It is also suitable for production companies that generate large volumes of waste. In this field of application, it size reduces the material so it can be processed further at the same facility or to facilitate transportation to the treatment company. A typical application involves plastic barrels, which are collected centrally at one location in a company and then shred in order to reduce the transport costs for further processing.
Dennis Kemmann, Managing Director of BHS-Sonthofen GmbH, has completely redesigned the machine with his team: “Our aim is for our customers to achieve the lowest possible processing costs per ton. Before getting down to the design, we asked many users what their main shredding requirements were. Their answers and the long-standing experience of our engineers were incorporated into the design. The result: A completely newly developed machine that economically shreds everything you can possibly cut.”
BHS added many technology advances insuring excellent machine uptime. This begins with the sturdy design and long service life of the individual components and extends from the simple removal of contaminants through to short maintenance times and the rapid availability of spare parts.
The loose feed material is loaded into the feed hopper, which BHS-Sonthofen individually adapts to the material and type of feeding.
A hydraulically driven slide pushes the material along the base plate and toward the cutting system where granulation takes place. The rotor is equipped with replaceable blades, and the stator has an adjustable counter-blade with a material specific profile. BHS configures the style, quality and number of blades to the specific application at hand.
Once the cut material reaches a defined partical size, it falls through a screen basket downwards and out of the machine. The size of the discharge material is defined by the hole size of the screen, it can be between 20 and 100 mm. The screens are individually replaceable and can be rotated at 180°, increasing their service life considerably. The screen basket can be lowered downwards. In this way, BHS avoids the need for overhead work when inspecting the machine or replacing the screen.
As contaminants can never be fully prevented from falling into the feed material, the base plate is mobile and can be lowered from the cutting gap, if required. This allows for fast removal of contaminants. The screen basket can also be folded away for inspections.
The throughput depends to a large extent on the density and toughness of the material as well as the method of feeding. Interested parties can request that the company perform tests in their technology center at the Sonthofen plant, to determine the ideal machine configuration. This gives customers the certainty that their material will be processed efficiently.
BHS-Sonthofen supplies the machine in two versions: The Universal Shredder of type NGU 0513 with a rotor length of 1300 mm for a throughput of up to 5 t/h as well as type NGU 0518 with a 1800 mm rotor for up to 6.5 t/h – each based on a hole diameter of 30 mm. The motor drives are available up to 132 kW.
The drives are frequency controlled, and the speed of the rotor is adjustable between 80 and 240 rpm. As a result, the machine can be configured to account for the properties of different feed materials. For easy to shred materials, for instance foils, high speeds are preferable in order to attain a high throughput. Solid semi-finished plastic products, full plastics as well as thick or heat-sensitive materials are shred at lower speeds.
The blades of the rotor shaft can be utilized on both sides and are rotated with minimum manual effort. The counter-blade can be adjusted. This ensures that the cutting gap is always optimally calibrated. It can also be used on two sides and replaced within the shortest time.
The design engineers have also attached considerable importance to high availability in the context of adapting the machine to various requirements: The screen basket can be changed within a few minutes. This is advantageous when destroying files, for example, if different protection classes are applicable in successive batches.
Recycling machines from BHS-Sonthofen:
When taking over AMNI Maschinenbau GmbH in 2013, BHS-Sonthofen extended its product portfolio of recycling machines by adding shredders and granulators with cutting technology. Today, the company offers a wide range of shredders, granulators and crushers with impact and shear crushing alongside cutting technology.
At IFAT, BHS will present a further single-shaft crusher for the first time: The new “SpeedCut Granulator” of type NGV with a throughput of up to 15 t/h is designed for the granulation of domestic refuse or industrial waste for refuse-derived fuels.
BHS-Sonthofen will also continue manufacturing the proven “HeavyCut Granulator” of type NGH with swiveling stator for heavy feed material such as tires, electrical and electronics scrap or aluminum composites.
