The VNZ double-shaft re-shredder was developed for re-shredding pre-shredded used timber, pre-shredded municipal solid waste, sorting waste, and much more in order to produce separable material for recycling and reutilisation.
Different rotor systems and geometries are available to optimise the shredding capacity with different material. The two solid steel rotors with a diameter of 500 respectively 640 mm maximise the shredding efficiency. The machine is equipped with the "Flipper", a pneumatically pre-tensioned counter knife that prevents damage if tramp materials are fed in. This also makes it easy to remove tramp material without having to unload the hopper. The VNZ XL also features two large hydraulic access doors that make wear parts easier to replace and allow tramp materials to be removed, even when the hopper is completely full. The drive capacities range from 2 x 75 kW to 2 x 200 kW. The screen mesh sizes are normally between 20 and 150 mm. Depending on the size of the machine and the mesh size, throughputs of between 5 and 40 to/h can be achieved. In addition to the standard drive, the VNZ XL is also available with the patented HiTorc drive VNZ Xl T, which reduces power consumption by up to 60% compared to the standard drive system. The drive capacities range from 2 x 134 kW to 2 x 203 kW.
