Wood and paper shredder – the Hacker WL 6 from WEIMA

The aggressive WEIMA rotor principle ensures powerful and continuous material intake. Even bulky or voluminous wood waste is reliably collected and shredded. The result is high throughput combined with a stable process – ideal for businesses with high material volumes and cost-effective requirements.

The specially developed hopper design ensures a consistent feed of material without bridging. The material fed into the hopper moves forward in a controlled manner, thereby preventing interruptions in the shredding process. This enhances process reliability and significantly reduces the need for manual intervention.

The hydraulically controlled feed gate automatically adjusts to the material load and feeds the material evenly to the rotor. This prevents bridging, reduces the need for manual intervention and ensures consistently high grinding quality with defined particle sizes. The load-dependent control system minimises wear and ensures stable operation under varying production conditions.

The screening system can be adapted to the requirements of various applications: depending on the desired particle size, either a fine-mesh or coarse-mesh screen can be fitted. The standard screw-on mounting allows for quick screen changes and ensures consistent grinding results, which optimally supports further processing or the extraction system.

The sensitive hydraulic components are integrated into the machine frame, thereby protecting them from dust, dirt and the elements. A separate service access panel allows for easy maintenance, whilst the protection of the hydraulic system increases machine availability and reduces unplanned downtime.

Depending on operational requirements, the shredded material can be discharged via a vacuum extraction system, a discharge screw or a conveyor belt. This integration into existing conveying and disposal systems enables a seamless process chain without the need for additional modifications and supports the efficient recycling of waste materials.

The rubber machine feet effectively absorb vibrations and ensure stable machine operation without the need for fixed floor anchoring. This improves the working environment, reduces stress on the structure and supports smooth, reliable production over long periods of operation.

The compact, robust design, featuring an internal WAP gearbox and a powerful electric motor, ensures continuous operation even during demanding shredding tasks. The in-house developed gearbox delivers high torque reserves, is easy to maintain and reduces mechanical stress. This extends the machine’s service life and lowers total operating costs in industrial applications.

The offset position of the rotor bearings provides reliable protection against dust, dirt and material ingress. This significantly reduces the load on the bearings and extends maintenance intervals. The result is a durable design offering high operational reliability – even during multi-shift operation.
