Zerma GST 250/450

Optimization of an established concept.

Size reduction of large-volume blow-molded parts as well as start and end pieces

The best features of the proven GST and GSC series have been integrated into a compact redesign, with particular emphasis on weight, handling, and energy efficiency. These compact granulators are equipped with complete sound insulation, resulting in extremely quiet operation. The granulators are available with a 250 mm rotor diameter and widths of 300, 450, and up to 600 mm. The curved back wall of the cutting chamber ensures aggressive material intake and prevents material jams. As with all ZERMA granulators, the rotor and stator knives are adjustable outside the machine, thereby reducing downtime during maintenance.

The highly tangential, curved rear wall of the cutting chamber combined with the aggressive, open rotor design ensures reliable material intake and minimizes the risk of blockages.

These compact granulators are suitable for use in blow-molding operations. They are ideal for recycling voluminous items such as bottles, canisters, and crates. Thanks to the low infeed height, these machines can easily be loaded by hand or with a small conveyor belt. Low noise emission and minimal space requirements make the granulator the perfect solution for inline size reduction.

Optional rear wall with elevated stator knife, M version:

The infeed method with an elevated stator knife is better suited for thicker-walled and more compact parts, such as injection molded components, profiles, plates, etc. The cutting geometry and reduced aggressiveness of the rotor produce high-quality regrind independent of the material type or form, such as injection molded parts, profiles, plates, etc.

Control cabinet and control system:

The integrated control panel and operator console not only comply with all applicable safety regulations but can also be adapted to specific requirements. In addition, peripheral devices such as feed conveyors, metal detection, and discharge systems can be seamlessly integrated with the machine’s control system. For enhanced efficiency, an optional intelligent energy-saving function is available, which reduces power consumption during idle periods and can automatically start and stop the system based on the status of upstream machinery.
