The WL 4 single-shaft shredder from WEIMA has proven themself to be the classic shredder for wood waste of all kinds, and can be found in thousands of woodworking shops all over the world. The global popularity of this shredder series assures high reliability at a competitive price to performance ratio. These machines set themselves apart from other machines of their size and type due to their robust construction, giving them a longer life cycle.
Intuitive operation thanks to Siemens PLC control with touch display
To ensure that the electronics are optimally matched to the machine, they design, build and wire their control cabinets ourselves. WEIMA only use high-quality components – for example from Siemens or Rittal. Intuitive touch interfaces guarantee quick adjustments. Functions such as setting the ram cycle or stop ensure a high throughput. The built-in overload protection also prevents defects in the machine.
Precise cut with high throughput with profiled V rotor
The V rotor, specially developed by WEIMA, can be used universally and is made of solid material. Its aggressive material feed with up to two rows of knives guarantees high throughput with low power requirements. It can be equipped with hardened steel cutting knives in edge lengths of 30 mm and 40 mm. These can be turned over several times in case of wear, which drastically reduces maintenance costs.
Chopping and heating
The Sucker Holzbau GbR produces a lot of wood waste. With the help of a WL 6 shredder and a wood chip stove, this is used to heat the workshops and offices as well as three single-family houses.
No material bridges due to free-cutting hopper design
The hopper fulfills several tasks at once. First, the material to be shredded is fed through it – manually, mechanically, or by conveyor belt. The generous opening makes it easy to fill even very large parts. A decisive factor for shredding, however, is its special design, which is rounded at the front and thus effectively prevents material bridging. Even with bulky parts, the shredder cuts itself free. If required, hopper extensions and lids with gas pressure springs are available.
