» General information
The GS range of high performance granulators are based on the latest machine concepts
which have been perfected throughout the years and leave nothing lacking.
They can solve almost all problems of plastics granulation.
The housing, which is of a robust welded steel construction, is suitable for universal applications
due to the removable deflector wedge and is designed to meet the most demanding applications.
Depending on the required application, there is a whole range of rotor options
from the open 3-blade, aggressive bite types through to the heavy duty, semi-closed, 9-blade types.
All machines in the GS range produce a high quality granulate whether it be from injection moulded articles,
sprues, pipes, profiles, sheets, film or start-up and headwaste lump.
The machines are economical, reliable, easy clean and have long service life.
All GS machines are also available with integral soundproofing.
ZERMA can also offer the wide range of necessary ancillaries such as blowers, suction systems,
conveyor belts, metal detectors, fines separators etc.
To put it concisely: Ultimate Granulator Technology!

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 removable 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 across the centre line and the upper part can be opened hydraulically (GS 350/500 and 400/600 manually). 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.
