Single shaft shredder ZERMA ZPS
Our single-shaft shredders from the ZPS series can be used universally.
They are suitable for shredding solid parts and films that cannot be
shredded directly on a granulator.
General description
The material is transported via the load-dependent controlled hydraulic pusher to the rotor. The slowly rotating rotor is equipped with cutting crowns which, together with the stator knives in the housing, shred the material. The final fineness is determined by the screen located under the rotor.
It is driven by a drive motor, V-belts and a generously dimensioned gearbox.
The large and heavy rotor of the ZPS shredder series, the low rotor speed and the high torque ensure low current peaks and thus avoid high energy costs.
The shredders from the ZPS series are equipped with equipped with a 2-stage hydraulic system that prevents the rotor from jamming. Knife and blade holder are completely screwed into the rotor.
Generously dimensioned, externally mounted rotor bearings and a hydraulically pivoting screen basket are part of the standard equipment of every shredder.
ZERMA ZPS-Details (Preview)

Hydraulic pressure device
With its generously dimensioned bearing it guarantees an optimal feeding of the material to the rotor.

Front panel with serrated edges
The front plate of the feed pusher is
equipped with serrated strips to ensure that bulky parts are securely held.

Hydraulic
It is load-dependent controlled and has a 2-stage hydraulics, i.e. the reverse movement takes place vat increased speed.

Rotatable cutting crowns
The rotors are equipped with
concave shaped, rotatable
cutting crowns.
