Wood waste shredder – the WL 20 from WEIMA

To precisely control one or more machines, including their conveyor systems, all you need from WEIMA is a single control cabinet. The built-in Siemens PLC control system is optimally tailored to the shredding process. Various slide valve controls and rotor settings can be easily adjusted to suit the desired application. All control cabinets are designed in-house and built at our German production facilities.

Many of our customers describe the profiled V-rotor as a true all-rounder when it comes to shredding. With two rows of blades, the material feed is optimally designed. The V-rotor delivers high throughput, low energy consumption, reduced thermal stress and low wear costs.

The pusher feed can be controlled manually, in cycles or based on load. Depending on the application, it may be advisable to enhance the standard material pusher with technical options. To prevent jamming and improve guidance, the pusher can be mounted on rollers. WEIMA also recommends the use of a segmented floor – particularly for very thin materials.

Shredding particularly tough materials requires suitably robust bearings that are easy to maintain. WEIMA therefore uses durable self-aligning roller bearings, whose sturdy construction and mounting away from the machine frame protect against impacts and uncontrolled force transmission. Their additional shaft seal effectively prevents the ingress of contaminants or dust.

Adjust the screen to suit your needs. The smaller the hole diameter, the finer the crushed material that is discharged. Screens can be easily swapped and are bolted in place as standard.

For most applications, electromechanical drives are the traditional choice, as they are low-maintenance and robust. What sets WEIMA apart is that we manufacture our own gearboxes, which are specifically designed for shredding operations. Torque monitoring and shock-absorbing vibration dampers complete the package. A hydrodynamic start-up clutch is available as an option to provide additional protection for the machine.

The shredder’s feed gate is moved back and forth hydraulically. With the turbo-hydraulic system, this happens even faster. For continuous operation, an additional oil cooling system and a length measurement system are available as optional extras.

Thanks to compact hard-rubber feet, there is no need to anchor the machine to the floor. This allows for flexible positioning. More importantly, disruptive vibrations that have a negative impact on the surrounding area are effectively prevented.

WEIMA shredders easily break down pallets into wood chips, which can then be used as a fuel source for your own heating system or sold at a profit. Nails and foreign materials can be removed using a magnet.
