The powerful and flexible cross flow cutting tool / impact hogger will be deployed for shredding and breaking of various materials. The WQZ can go completely without wearing tools, e.g. pivoting and standing cutters or granulating screens. Approx. 80% of the shredder takes place through the sole mutual clash of the accelerated feedstock. Consequently, it won´t get cut, but milled. Different physical properties of the materials define various grain sizes. Individually adjustable dwell times defined the form and the size of the open materials.
