Hitri granulator

ZERMA GST 250/300

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

In a compact redesign, the best features of the proven GST and GSC series have been integrated, 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 600 mm. The curved rear wall of the cutting chamber ensures aggressive material intake and prevents material blockages. As with all ZERMA granulators, rotor and stator knives can be adjusted outside of the machine to minimize maintenance downtime.

The strongly tangential, curved rear wall of the cutting chamber, in combination with the aggressive open rotor design, ensures reliable material feeding and minimizes the risk of blockages. These compact granulators are suitable for use in blow moulding operations and are ideal for recycling large items such as bottles, canisters, crates, etc. The low infeed height allows the machines to be easily loaded by hand or with a small conveyor belt. Low noise emissions and minimal footprint make the granulator the perfect solution for inline size reduction applications.

The feeding method with a higher stator knife is better suited for thicker-walled and more compact parts such as injection-moulded parts, profiles, sheets, etc. Due to the cutting geometry and reduced aggressiveness of the rotor, the machine produces high-quality regrind regardless of the material type or shape, such as injection-moulded parts, profiles, sheets, etc.

Control system and control cabinet:
The integrated control and operation console not only complies with all applicable safety regulations but can also be customized to meet specific requirements. Additionally, peripheral devices such as feed conveyors, metal detection, 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 automatically start and stop the system based on the status of upstream machines.
