The S120 is one of the most innovative pre-shredders in its class. A sophisticated cutting strength distribution system ensures that the cutting tooth briefly receives up to 70% more cutting strength for materials with highly variable cutting strength requirements (e.g. thick-walled metal pieces). Together with its high throughput performance, high availability and low maintenance requirements, this shredder guarantees an economically efficient recycling of your material. The S120 is a rotary shear shredder that is often used as pre-shredder for difficult applications. Apart from its very resistant and sophisticated cutting system and flexible drive concept, the shredder is also convincing thanks to its high throughput performance. By linking four motors, the system reaches a high torque of max. 2 x 35,000 Nm. When needed, this torque is distributed to the respective cutting tooth at peak moments (see cutting strength distribution system). This rotary shear is also characterized by a particularly high availability. This machine is particularly low maintenance thanks to special bearing and gearbox sealings, an integrated cutting system protection and an optionally available shaft ventilation. In the field, this machine is connected with an UNTHA 4-shaft shredder downstream to achieve a homogeneous, separable and also smaller final fraction.
