Condition: new, Year of construction: 2026, Weima Hacker/Shredder WL 8 with Top Equipment - Four-sided segment floor, discharge auger with geared motor, double blade row, log spacer, fast reverse hydraulics with shock valve The single-shaft shredder WL 8 is a proven classic for shredding wood waste of all kinds. It is used thousands of times in wood processing companies worldwide. The high number of these highly sought-after shredders guarantees a proven and reliable technology at the best price-performance ratio. The machines are characterized by their very robust design, which ensures extremely high durability (even outdoors). Dcjdpjmhh Idsfx Aptol Intuitive operation thanks to Siemens PLC control with touch display To ensure that the electronics are optimally adapted to the machine, we design, build and wire our control cabinets ourselves. We use only high-quality components – for example, from Siemens or Rittal. Intuitively operated touch interfaces guarantee quick adjustments. Functions such as setting the slide timing or stop ensure a high throughput. The built-in overload protection also prevents damage to the machine. No material bridging thanks to self-cleaning hopper design The hopper performs several tasks. First, the material to be shredded is fed into it – manually, mechanically or via a conveyor belt. The generous opening also makes it easy to fill in very large parts. However, its special design, which is rounded at the front and thus effectively prevents material bridging, is decisive for the shredding process. Even with bulky parts, the shredder cuts itself free. If required, both hopper extensions and lids with gas springs are available. Durable rotor bearings thanks to offset design A rotor bearing must be particularly robust due to the extreme stress it is subjected to during the shredding process. To prevent dust or foreign matter from entering its interior, we have separated it from the machine frame. This also makes it very easy to maintain and access.

Condition: used, Year of construction: 2025, New demonstration machine! List price €25,500 net. Machine concept WL 4 / 18.5 kW. The Weima high-performance shredders, with their flexible application options, can process all types of wood-based materials (hardwood, softwood, chipboard, MDF materials, plywood, veneer remnants, etc.) into wood chips, and achieve an enormous volume reduction of the material, especially with bulky materials. Operating principle: The machine is equipped with a large feed hopper and can be fed either via a conveyor belt or by hand. This hopper can be adapted to individual needs and guarantees a continuous and cost-effective material feed without the need for manual assistance. The hydraulically controlled slide feeds the wood waste to be shredded to the cutting area of the rotor and is automatically and load-dependent. The internal slide guides are made of highly abrasion-resistant plastic (polyamide) and can be adjusted. The hydraulic cylinders are suspended on universal joints to avoid transverse forces on the piston seals. The patented and profiled V-rotor made of solid steel has a diameter of 256 mm and operates with a rotor speed of 80 - 120 rpm. The concave, aggressive and 4-way rotatable knives/cutting inserts are located in milled knife pockets on special knife carriers. This patented system guarantees, through the resulting reduction of the cutting gap between the counter-knife and the rotor, a high throughput, low energy consumption and an optimal discharge of the shredded material. The screen attached under the rotor determines the chip size (10 - 100 mm). On request, a hydraulically opening screen basket is also available. The power transmission from the electric motors is via V-belts to a heavily dimensioned gearbox, which is attached to the rotor stub on one side.
