ZERMA GST 250/300

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

In a compact redesign, the best features of the proven GST and GSC series have been combined, 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 are adjustable outside of the machine, thus reducing downtime during maintenance.

The strongly tangential, curved rear wall of the cutting chamber in combination 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, e.g., voluminous items such as bottles, canisters, and crates. Thanks to the low feeding height, the machines can be easily loaded manually or with a small conveyor belt. The low noise emissions and small footprint make the granulator a perfect solution for in-line size reduction.

Optional rear wall with elevated stator knife, M Version:
The feed method with an elevated stator knife is better suited for thicker-walled and more compact parts, such as injection molded parts, profiles, sheets, etc. Due to the cutting geometry and the less aggressive rotor, high-quality regrind is achieved regardless of the material type or shape, such as injection molded parts, profiles, sheets, etc.

Control system and control cabinet:
The integrated control system and operator console not only comply with all relevant 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 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 upstream machine status.

Standard configuration with blower, power consumption 0.75 kW and 400 cyclone
