VNZ - Re-shredder

Powerful re-shredding of pre-crushed material

With our VNZ series, you get high-performance secondary shredders in a robust design, which have been specially developed for the re-shredding of pre-crushed material to produce separable material for value and material use. Waste wood, pre-shredded domestic, industrial and commercial waste, production waste, straw, root wood and much more can be processed without any problems. Various rotor systems and geometries are available for optimum shredding performance with different material tasks.

VNZ - Re-shredder

The strongest among the double-shaft re-shredders

The Vecoplan double-shaft shredder was developed for the re-shredding of pre-crushed waste wood, pre-shredded domestic,industrial and commercial waste, production waste, straw, root woodand much more. We can deal with a great variety of input materialsand match customer requirements, thanks to our different cuttingtools, counter-knife variants and matching perforated screens.

The highlights of the VNZ - Re-shredder

Indestructible power thanks to a robust construction

The basis for efficient and trouble-free operation is the machine housing, consisting of a thick-walled, ribbed construction with optimum functional machine geometry.

The two solid steel rotors with their large flywheel masses ensure smooth machine operation and high throughput. The interaction of the two rotors with the common counter knife and the perforated screens results in a very separable and homogeneous output. Hydraulic maintenance doors facilitate the replacement of wear parts and the removal of impurities, even when the filling hopper is completely full.


Your advantages at a glance

  • Highest reliability and availability
  • Cost minimisation through energy efficiency
  • Optimisation of maintenance and service
  • Best added value through consistently high, high-quality output
  • Support through Vecoplan Live Service


The HiTorc drive is a frequency-controlled, powerful high-torque motor with a variably adjustable speed range that can also start up under load. The virtually maintenance-free and noiseless drive has an energy saving of up to 60% compared to conventional drives.

The maintenance doors can be swivelled hydraulically. Due to the good accessibility, it facilitates the changing of wearing parts and the removal of impurities.

Due to the different screen perforations, the output grain size can be optimally adjusted. The screen basket is very easily accessible for cleaning and maintenance work.

The counter knife is multi-piece and hardened. The small blade gap optimises the cutting performance. The lowerable counter-knife cross-bar (pneumatic) supports maintenance work and the removal of impurities. The "flipper" (machine breakage protection) protects the machine from damage.

Hydraulic swivelling of the maintenance doors.

The rotor is equipped with concave knives that achieve long service lives and can be used up to 4 times each.
