Single-shaft shredder, model WL 10, for wood and paper

The Siemens PLC enables precise control of all relevant process variables, including gate and rotor parameters. Operating conditions can be quickly adapted to different material flows via the control panel, which minimises set-up times and ensures consistent performance even with varying waste qualities. The central control system also simplifies integration into higher-level automation networks.

The contoured V-rotor, featuring two rows of cutting blades, optimises material intake and ensures high throughput rates whilst reducing energy consumption. The curved rotor geometry improves the feed of bulky wood and paper waste and reduces thermal stress in the cutting zone, thereby increasing efficiency during continuous operation.

The hydraulically driven feed gate positions the feed material precisely in front of the rotor and can be controlled based on load, manually or in cycles. This precise guidance prevents jamming and ensures consistent shredding performance, which enhances process reliability, particularly with mixed waste streams.

The rotor bearings are separated from the machine frame and protected from dust and foreign particles by robust seals. This bearing arrangement reduces mechanical stress, extends maintenance intervals and enhances reliability in continuous industrial operation.

The standard screw-mounted screening system can be flexibly adjusted to the desired particle size. Smaller hole diameters produce finer particles, which improves the homogeneity of the ground material and enhances its suitability for downstream processes such as extraction or pelletisation.

The low-maintenance electromechanical drive combines a powerful electric motor with an in-house WAP gearbox. This solution provides high torque reserves, reduces mechanical stress and simplifies servicing, thereby increasing the machine’s uptime.

The turbo-hydraulic system accelerates the movement of the material pusher, thereby increasing the effective feed rate. Combined with optional oil cooling and a length measurement system, this configuration is suitable for demanding continuous operation with high material volumes, without disproportionately increasing energy consumption.

The vibration-damping feet minimise the transmission of vibrations to the hall floor and the surrounding area, thereby improving the working environment. At the same time, there is no need for fixed floor anchoring, which increases installation flexibility and protects the service life of adjacent systems.
