RKW says that the V-Eco machine is flexible and focuses on energy-efficient operation. It shreds extremely difficult materials with high-quality results and at a high throughput. The decisive advantage is its cutting geometry. The technology can be adapted to input and output requirements by changing the rotors and blades and selecting the right screen. Vecoplan fine-tuned these components for use at RKW by selecting rotor diameters, cutting geometries, screens and cutting tools to correspond to the mechanical properties, thermal properties and dimensions of the input material and the output requirements. As a compact machine design, Vecoplan says

Managers can also use their smart- phones, tablets or laptops to monitor machine operating states remotely. “Digitalisation, Industry 4.0 and the ability of our machines to make predictions based on data were the main factors that drove our decision to launch a new user interface for the control panel,” says Daniel Kessler, Head of Electrical Development at Vecoplan. The company says that the new operating concept supports the user by increasing the transparency and productivity of these solutions and making their operation more energy efficient, with statistical data recorders, for example, and dashboards – it also records all the machine parameters, which can also be exported. The new user interface can be used on all conventional mobile devices. Additional user benefits include the digital provision of service videos and machine documentation with self-explanatory pictograms and simplified images. The control elements can also be personalised and saved to match the needs of every individual operator. German films manufacturer RKW is using
Vecoplan’s shredding technology to recycle its production waste. RKW specialises in the develop- ment and production of high-quality plastic film and netting for round balers in agriculture. The company uses film waste from various production locations in the RKW Group. Previously, the waste was sent directly to a recycling plant. Now the company has significantly optimised the recycling process by investing in a shredder from Vecoplan’s V-Eco 1300 series, which includes equipment for conveying, separation and storage. This highly efficient system not only provides RKW with very homogeneous output material, it also helps the film manufacturer to cut costs, optimise its work processes and increase its production of regener- ated material.

that this reduction down to the essentials minimises susceptibility to failure, optimises the material flow and makes all service and maintenance work easier for users. The hydraulically swivelling bottom flap and the downward-swivelling screen allow easy access to the rotor for operators, who can immedi- ately remove extraneous material, exchange the counter knife or adjust it from the outside. Material feed to the rotor is continuous due to the inclined design of the machine floor and the continuously adjustable ram control. This ensures that the process is uninterrupted. For energy-efficient operation Vecoplan also installed the cost-effective Electronic Slip Control drive, which makes gears and turbo clutches unnec- essary. The multipole, asynchronous drive motor with its powerful frequency converter works together with a special belt drive that incorporates slip control and
