Condition: new, machine/vehicle number: Baureihe GSP, When shredding long pipes and profiles, conventional granulators face significant challenges. In most cases, pits or platforms are required to feed the long and bulky parts. This is why ZERMA developed the GSP series. Thanks to the nearly horizontal feed hopper, long pieces can be easily fed, and the risk of blockage is eliminated as the machine meters the material automatically. When the grinding chamber is overfilled, no further material is accepted until the machine can operate again without overloading the motor. Dujdpfx Aasyr Thke Not ZERMA also offers a wide range of options such as extraction systems, conveyor belts, metal detectors, fine material separators, and more.

Condition: new, machine/vehicle number: GSH, The ZERMA GSH series granulators are exceptionally robust machines designed for the most demanding applications and tailored to the diverse requirements of modern recycling operations. The housings, constructed from heavy-duty steel and welded for maximum strength, withstand even extreme loads. All assemblies related to bearing support, knife mountings, and the rotor shaft are significantly oversized, resulting in outstanding durability. With simple reconfiguration, the machines can effortlessly shred both massive lumps, thick-walled pipes, and also hollow bodies or films. Depending on specific requirements (including for temperature-sensitive materials), various rotor designs are available, all featuring the advanced and superior V-cut technology. All GSH series machines consistently deliver high-quality regrind – whether processing bottle crates, profiles, sheets, films, start-up lumps, or pipes. They are economical, exceedingly reliable, easy to clean, and built for long service life. When combined with ZERMA’s extensive range of options and accessories—such as extraction systems, conveyor belts, metal detectors, fine particle separators, roll-feed devices, etc.—as well as spare parts, the result is a custom-optimized size reduction solution. The advantages include significantly reduced costs, time, and personnel requirements. Thoughtful machine housing design The housing is centrally divided at an angle, and the upper section with feed hopper can be opened hydraulically, providing unrestricted access to the rotor for knife changes and cleaning. The screen insert is also held in place by a hydraulically swiveling screen cradle, ensuring optimal accessibility for quick removal and installation. The screens are reversible. Rugged external bearing arrangement Another well-conceived design feature is the external bearing arrangement. Heavy-duty rolling bearings in steel bearing housings guarantee long service life and are ideal for even the toughest demands. The external bearings prevent grease from entering the cutting chamber, as well as preventing regrind or fine particles from getting into the bearings. This offers a distinct advantage, particularly during wet operation. Dsdpfx Ajyr Thdoa Nout Flywheel To absorb shock loads during granulation, an optional flywheel is available. For this purpose, the rotors are supplied as standard with a second shaft end. High operational safety All granulators conform to EU machinery directives and carry the CE mark. Accident prevention is ensured, for example, by run-down safety devices with limit switches, as well as hydraulically unlockable non-return valves.
