Rotor repair & new build

From 25-tonne shredder rotors to 500 kg hammer rotors: every year we repair over 100 different rotors for the recycling and natural stone industries, in our own workshop in Lengerich, Germany.

Over 40 years of experience and repairing ever more makes have shown us where rotors are weak and how to refurbish them for the long term. That know-how goes into every repair, from dismantling and measuring to final inspection by our quality assurance.

Before delivery, we test every rotor on our own rotor test stand for imbalance and smooth running and balance it dynamically with measuring instruments, whether it is a new build or a repair.

• Bearings, shaft and all components checked
• Final test by our quality assurance
• Ready for use as soon as it is released

The wire and welding process we use depend on your application and the condition of the rotor. We apply protective weld overlays to new builds and repairs in our workshop and, if the rotor is not too heavily worn, right in your machine. The rotor is then dynamically balanced.

• Full or wear-zone hardfacing
• Protective weld overlay on rotor discs
• In our workshop or right in your machine
• Less vibration, longer bearing life
