Chain of the Universal Cross-Flow Shredder QZ

Universal Cross-Flow Shredder QZ: Gently opening up of material composites

The Universal Cross-Flow Shredder QZ does completely without the use of knives and opens up the input material particularly gently and quickly using impact forces.

In comparison with conventional cutting systems the QZ offers significant advantages concerning the result and wear. The Universal Cross-Flow Shredder QZ is suitable for a number of different materials and composites. The machine concentrates on the disintegration of the input material, but avoids an undoing and damaging of the individual components. It is therefore possible to quickly access disintegrated valuable waste material, without potential harmful substances emanating from individual parts.

Operational principle

Flexible turning tools accelerate the input material to variably adjustable speeds and circles. Approx. 80% of the disintegration and the opening up are carried out by the impact of the accelerated materials with each other. The different physical properties of the materials as well as the individually adjustable holding time determine the form and size of the processed material.
