W8.15 FineCut – Shredder for secondary shredding of waste

The FineCut achieves high process stability and a configurable throughput thanks to a Siemens S7 controller with a touchscreen display and adjustable settings for rotor speed and slide cycle. This technical design enables rapid adaptation to different material characteristics and reduces waste as well as fluctuations in the shredding process.

An externally adjustable counter-blade system, which can be adjusted via a screw mechanism and utilises angled protective cover plates, ensures the production of defined fine fractions. This design guarantees consistently repeatable cutting gaps, improves material homogeneity and enhances the quality of the end product in downstream processes such as RDF production.

The load-dependent swing ram directs the material precisely into the rotor chamber, with an optional pusher and turbo-hydraulics to increase the gate speed. This technical solution increases effective throughput, reduces blockages and optimises energy efficiency with varying waste streams.

The automatic central lubrication system, mounted on the side of the machine frame, continuously supplies grease to all relevant bearing points. This eliminates the need for manual lubrication intervals and reduces the frequency of unplanned downtime, thereby improving operational reliability and extending the service life of moving components under industrial loads.

With the characteristically designed FineCut rotor made from solid material, you can achieve particle sizes of up to 15 mm at high speeds of 160 to 380 rpm. The cutting blades can be re-sharpened multiple times. The rotor features up to seven rows of blades, enabling very high throughput rates. A splinter guard is also fitted as standard. A multi-spline shaft pin is fitted on the drive side to ensure a secure fit. The compact design also provides ample lateral expansion space for the material. This technical configuration enables high shredding performance whilst reducing the need for reworking and energy consumption.

Adjustable heavy-duty feet on the base frame stabilise the machine even on uneven surfaces and ensure low-vibration operation. This reduces mechanical stress on the rotor and bearings and contributes to process reliability and long-term machine availability.

The choice is yours: our FineCut shredders can be fitted with a Hägglunds hydraulic drive, a high-torque drive from Baumüller, or a conventional electromechanical drive. Which one is right for you always depends on your specific application.

Standardised interfaces and a raised machine frame height facilitate integration into existing conveying and processing lines. This enables users to create flexible system designs with reduced planning time and high line availability thanks to simple mechanical and electrical connections.

Users benefit from short changeover times when switching between different material flows, thanks to a screen basket that can be swung upwards hydraulically. The bolted-on, wear-protected screen segments can be changed quickly and, in combination with secondary shredders, allow the final particle size to be precisely set between 15 and 80 mm. In industrial operation, this increases plant flexibility, reduces downtime and enables reliable adaptation to varying output requirements.

Hydraulically operated inspection flap at the front and rear provide direct access to the screen and rotor chamber for maintenance, blade replacement and the removal of foreign objects. This design reduces inspection times, simplifies on-site operation and minimises average machine downtime.
