» General information

The ZERMA GSH series granulators are designed for the most extreme and universal applications required for todays plastic recycling facilities.

The completely welded heavy steel manufactured construction is designed to withstand the most demanding and universal applications due to the removable deflector wedge (third stator knife).
Rotor bearings, knife mounts and rotor shaft are oversized to cope with extreme feed stock.

Depending on the required application the GSH series offers a complete range of rotor variants which are all built with the unique "V" cut technology.

The complete GSH range produces a high quality granulate, whether it be from bottle crates, profiles, sheet film, pipes or start-up lumps.The machines are economical, reliable, easy to clean and have an extremely long service life.

Zerma offers a wide range of necessary ancillaries such as material transport systems, conveyor belts, metals separators, roller feeders etc...

Superior cutting action

The rotor knives are mounted according to the latest V-cut technology. Contrary to the older cross cut action, the V-cut action conveys material to the centre of the rotor thus avoiding sticking and wear at the side walls.

Specially developed deflector wedge

A removeable adaptor carrying a third stator knife, termed the deflector wedge, can be installed to alter the first cutting point of the granulator as required. This simple installation option allows the machine greatest versatility.

Well thought-out housing design

The housing design is divided and the upper part can be opened hydraulically. Easily exchanged wear plates bolted to the side cheeks ensure long life. The screen is held in position by a hinged cradle and is easily accessible.

Robust bearing assembly

The extremely robust pedestal bearing housings are mounted outside the machine separated from the cutting chamber to prevent dust and dirt ingress into the oversized bearings. This ensures a long life and minimum maintenance. otor.
