Single shaft shredder

ZERMA ZXS

The single-shaft shredder for demanding shredding tasks. The machines are extremely robust and achieve high throughput rates. Working widths from 1500 to 3000 mm and rotor diameters of 750 mm are available as standard.

General description

The ZXS series is equipped with a two-stage hydraulics. This prevents high current peaks and and possible rotor blockages.

The pusher device is guided without contact to the machine housing.
The rotors of the ZXS series have a 750 mm rotor diameter. These are mounted in oversized steel plummer block housings. The power is transmitted via V-belts in conjunction with generously dimensioned gearboxes at the respective rotor shaft ends.

The complete unit of the hydraulic power pack is space-saving, maintenance-friendly, separate and vibration-free mounted on swinging elements.

The rotor knives work as standard against a row of stator knives. The sturdy screen is bolted to the housing and can be opened and closed hydraulically.

Depending on the task, the single-shaft shredders are available with various wear options.

ZERMA ZXS-Details

Bolted rotor blade holders and rotor knives

The rotor knife holders are fixed or screwed (and not welded) in a pocket. The rotor blades are also screwed into the blade holders. Changing the knives / knife holders is quick and easy using the puller included in the scope of delivery.

Hydraulic pressure device

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

Bolted rotor shaft ends

Simplifies repair work enormously. They also they represent a predetermined breaking point to protect the machine from more serious damage.

Rotor with Hardox hard facing

For particularly abrasive and dirty materials.

Sieve

The sieve basket is operated via a separate hydraulic 2-hand operation. Maintenance work on the rotor, changing the sieve, the rotor knives blades and the rotor blade holders can be done easily and quickly.

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.

Optional cutting crowns

Special applications, such as the shredding of film or filaments, require flat, less aggressive cutting blades, which can be installed as an option.

Durable pedestal bearings

The robust pedeastal block bearings, that are separate from the grinding chamber, guarantee a service life.
