Defibrator system

The key features of the Evolution Defibrator system include a high-capacity screw-feeder system with a dewatering plug pipe and advanced helical discharge from the refiner housing.

 

This system includes a bearing system with no axial play, an exterior design that contributes to operating stability and facilitates access for easier maintenance.

Since launch, the EVO series has been expanded to include an EVO 46, EVO 50, EVO 56, EVO 64, EVO 70, EVO 74. Since its launch on Ligna 2005, the EVO series has been a great sales success and is operational on all of the world’s continents.
