VVZ - Pre-shredder
Powerful and efficient – twin-shaft shredders for pre-shreddingWith the twin-shaft pre-shredder, almost any material can be shredded. The HiTorc drive saves energy and the contaminant detection reduces downtimes.
Maintenance and service costs are minimised by easily replaceable wear parts. The output material is characterised by the best homogenity,
optimally prepared for the next process steps.
VVZ - Double-shaft pre-shredder
The strongest among the double-shaft pre-shredders
The Vecoplan double-shaft shredder is a pre shredder for difficult material and material containing extraneous materials, e. g. municipaland commercial solid waste, residual productionmaterials or wood waste, straw and root wood. With different cutting units, counter-knife variants and the specially adapted screen rod sizes, we can cater for the widest variety of input materials and customer requirements.
The highlights of the VVZ - Pre-shredder
Resilient power
The machine housing is a thick-walled, ribbed construction with optimal functional machine geometry for powerful and trouble-free operation with a maximum service life. This means maximum and continuous availability over many years at the highest level. With their large flywheel mass, the two solid steel rotors ensure quiet machine running yet have a high cut-through power. The interplay of the two rotors with the same counter-knife combined with the screen rods produces a high separation quality and homogeneous output. The two large hydraulic maintenance doors make it easy to change wearing parts and allow taking out tramp material even if the hopper is completely full.

Features
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 of the machine are equipped with a hydraulic locking system. The heavy guided locking bolt withstands even the highest pressure without any problems.
The cutting unit is equipped with two U-rotors for maximum cutting performance and high throughput. Each knife can be used up to 4 times. This means you benefit from a long service life and a homogeneous output material.
The multi-part counter knife is available in hardened or armoured version. The multi-part screen rods/screen grids promise low wear thanks to the armouring of the rods. In addition, the stripping combs on the maintenance doors prevent material entanglement on the rotor.
The output particle size can be easily adjusted thanks to screen rods extensions.
Large maintenance doors allow good access for changing wear parts or for discharging tramp materials.
