Shredding machine

Zerma GST 250/450

Optimization of an established concept.

Shredding of large-volume blow-molded parts as well as start-up and end-piece sections

In a compact redesign, the best features of the proven GST and GSC series have been integrated, with special emphasis on weight, handling, and energy efficiency. These compact granulators are equipped with full sound insulation, resulting in extremely quiet operation. The granulators are available with a 250 mm rotor diameter and widths of 300, 450, or 600 mm. The curved rear wall of the cutting chamber ensures aggressive material intake and prevents material blockages. As with all ZERMA granulators, the rotor and stator knives can be adjusted outside of the machine to reduce downtime during maintenance.

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

The compact granulators are designed for use in blow molding operations. They are suitable for recycling large-volume parts such as bottles, canisters, and crates. Thanks to the low feed height, the machines can easily be fed by hand or via a small conveyor belt. Low noise emissions and minimal footprint make this granulator the perfect solution for inline size reduction.

Optional rear wall with elevated stator knife M version:
The feed method featuring an elevated stator knife is more suitable for thicker-walled and more compact parts, such as injection-molded components, profiles, and sheets. The cutting geometry and reduced rotor aggressiveness deliver high-quality regrind, regardless of the material type or form, such as injection-molded parts, profiles, or plates.

Control system and switch cabinet:
The integrated control system and operator console not only comply with all current safety regulations, but can also be customized to address specific requirements. In addition, peripheral devices such as infeed conveyors, metal detectors, and discharge systems can be seamlessly integrated into 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 start or stop the system automatically based on the operating status of upstream machinery.
