WL 15 – Shredder for wood waste for huge demand

High shredding capacity
Consistent grinding results
Robust and low-maintenance design
Reliable material feed
Flexible PLC process control
Robust solid-material rotor

The WEIMA WL 15 is an industrial single-shaft shredder with an extended working width of 1,500 mm, designed for shredding large volumes of wood waste. As the all-rounder in the WL series, it is used in woodworking businesses and is suitable for the industrial shredding of materials such as pallet wood, production offcuts or bulky wood waste.

With flexible control, a profiled V-rotor and variable discharge options, the WL 15 offers higher capacity than the WL 10 and is ideal for larger material flows where higher throughput is required.

Below is an overview of the technical specifications, applications and available options for this proven single-shaft shredder.

The all-rounder with a screw-on sieve

Consistent crushing processes thanks to integrated Siemens PLC control

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.

Maximised shredding performance thanks to the versatile V-rotor

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.

Consistent material feed via a hydraulic slide gate with a serrated plate

The hydraulically driven ram 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.

Long service life thanks to offset rotor bearings with protective seals

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.

Adjustable particle sizes thanks to interchangeable screens

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.

Reliable performance thanks to a robust WAP gearbox and electric motor

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.

Increased material intake thanks to the turbo-hydraulic option

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.

Reduced vibrations thanks to vibration-damping machine feet

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.
