Shredder for long wood scraps – the WLH 600

A reliable power transmission ensures consistent performance under varying load conditions. The rotor is driven by an electric motor via a V-belt, which efficiently transmits torque. The absence of a gearbox and clutch reduces the number of components prone to wear. This increases uptime and supports consistently high throughput rates.

A robust design minimises downtime in industrial operations. The rotor bearings are separated from the machine housing and protected against dust and particles. At the same time, they remain easily accessible for maintenance and inspection. This extends service intervals and increases the service life of key components.

A consistent particle size is essential for stable downstream processes. A bolted round-hole screen with hole diameters ranging from 10 to 80 mm is installed beneath the rotor. The material remains in the cutting chamber until it passes through the specified screen aperture. This allows the output size to be precisely adjusted and adapted to different requirements.

Whilst Biber machines are fed directly via a manual inclined feed, WLH and Tiger shredders use a vibrating chute for material feeding. It is available in various lengths (up to 40 m) and conveys items such as long strips, profiles or pipes to the feed roller located in front of the rotor. The roller grips the material to be shredded and conveys it horizontally to the rotor, where it is shredded between the cutting blades and counter-blades. The horizontal machine design simplifies the handling of long parts. Compared to shredders with a conventional hopper, the material cannot fly out uncontrollably, which significantly increases safety.

Automated processes reduce the workload on staff and improve process stability. The machine is equipped with standard data interfaces for integration into higher-level control systems. In automated operation, material feeding and shredding are process-controlled without the need for manual intervention. This reduces intralogistics requirements and increases overall plant efficiency.

Short distances improve efficiency in the production environment. The horizontal shredder can be positioned right next to the processing machines. Waste material is processed immediately, without the need for temporary storage or additional transport. This reduces handling effort and stabilises the flow of materials in the workplace.

Stable process control ensures consistent output quality during continuous operation. The Siemens PLC is housed in a separate control cabinet and centrally controls all machine functions. Process parameters can be configured to suit specific applications and integrated into production lines via standard interfaces. This results in reproducible finished goods with a high level of process reliability.

The cutting geometry plays a key role in determining performance and energy efficiency. The V-rotor, featuring two rows of blades, works in conjunction with a controlled feed roller to ensure a continuous supply of material. This reduces peak loads and keeps energy consumption stable. Reversible and replaceable cutting blades ensure consistent cutting quality whilst minimising downtime.
