WLK 1500

The proven multi-talent with 1,500 mm working width

The WEIMA WLK 1500 is designed for high throughput rates and lend themself to the shredding of almost all types of waste - especially for: Plastics. Plastic lumps, pipes, automotive scrap, blow-molded materials (PE/PET/PP bottles, buckets, pallets and containers), as well as paper, cardboard, wood and light metals. Numerous machine options ensure optimum adaptation to any application. The shredder can also be ideally integrated as a pre-shredder in a two-stage process solution.

Flexible control for changing material flows

WEIMA only requires one control panel to precisely control one or more machines including the conveyor system. The built-in Siemens PLC control is optimally adapted to the shredding process. Various slide controls and rotor settings can be conveniently adjusted to the desired application. All control cabinets are designed in-house and built in our German production facilities.

Perfect cutting gap thanks to adjustable counter knives

The interaction between the cutting knife and the counter knife has a significant influence on the material throughput and the shredding result. To maintain a perfect cutting gap even with natural wear, counter-knives of this series are manually adjustable as well as reversible. Optimum cutting geometry keeps shredding energy-efficient, minimizes wear costs, and significantly extends the service life of the knife.

Universally applicable V rotor for demanding applications

Many of our customers describe the profiled V rotor as a best in class for shredding. The material intake is optimally designed with two rows of knives. The V rotor stands for high throughput rates, low energy consumption, reduced thermal stress and low wear costs.

Precise cut with F rotor for flexible materials

The F rotor impresses with its controlled infeed behavior and its precise cutting geometry – especially with flexible materials such as films, filaments or veneer. It can be equipped with either bolted-on or welded knife holders. In addition, a robust wear protection made of Vautid is possible for more abrasive materials.

Controlled material feeding by ram with serrated plate and segmented floor

The ram feed can be controlled manually, cyclically, or load-dependently. Depending on the application, it makes sense to supplement the classic material ram with more technical options. To prevent possible jamming and improve its guidance, the ram can be guided on rollers. In addition, WEIMA recommends the use of a segmented floor – especially for very thin materials.

Shredders of the WLK series can be used flexibly

Offset rotor bearings protect against dust and foreign matter

The shredding of particularly resistant materials requires correspondingly robust bearings that are easy to maintain. WEIMA uses long-life, spherical roller bearings, whose stable design and offset mounting from the machine frame protects against impacts and uncontrolled power transmission. Their additional shaft seal ring effectively helps against the intrusion of contaminants or dust.

Homogeneous shredding results thanks to flexible, interchangeable screen

Adapt the screen to your needs. The smaller the hole diameter, the finer the shredded material that is discharged. Screens can be exchanged flexibly and are bolted as standard.

Easy integration of conveyor technology thanks to generous belt cutout

Machines with a conveyor belt cutout make material discharge clean and efficient – ideal for production lines. For example, conveyor belts up to 600 mm wide can be seamlessly integrated. Alternatively, material can be discharged via suction or screw conveyors.

Robust electromechanical drive with in-house WAP gearbox

For most applications, electromechanical drives are the classic choice because they are easy to maintain and robust. WEIMA’s special feature: we manufacture our own gearboxes that are specially designed for shredding operations. Torque monitoring and shock-absorbing vibration dampers round off the package. A hydrodynamic start-up clutch is available as an option for further protection of the machine.

More space for material discharge

by raising the machine frame
If you need more space for discharge, we recommend the optional increase of the machine frame by up to 200 mm. This makes your production even more flexible.

Even higher throughputs with turbo hydraulics

The ram of a shredder is moved back and forth hydraulically. With turbo hydraulics, this happens even faster. For continuous operation, additional oil cooling and a length measuring systems are available upon request.

Vibration damping machine feet for less vibration in the building
Thanks to compact feet made of hard rubber, there is no need to anchor the machine to the plant floor. The installation remains flexible. More importantly, disruptive vibrations that negatively affect the surrounding area are effectively avoided.

Better material absorption for particularly large pieces

Instead of classic angled hoppers, WEIMA has relied on a design that is rounded along the front side for many years. This has two decisive advantages: the feed volume is increased. In addition, disruptive material bridges are effectively avoided – these occur especially with large material pieces. In this case, the shredder cuts itself free.

All the taste, none of the waste

Producing paper products generates a lot of waste. In the classic recycling cycle, the production waste or surplus is shredded and then returned to the production process. The Munich start-up company easy2cool has a different but equally sustainable use for paper waste. Using a WEIMA WLK 1500 Shredder, revolutionary and sustainable insulating elements are made from corrugated cardboard packaging.
