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. 98T8Mrx 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. Standard configuration with blower, power consumption 0.37 kW, and 400-type cyclone Rotor diameter (mm): 250 Rotor width (mm): 450 Drive (kW): 7.5 Number of rotor knives: 3 x 2 Number of stator knives: 2 Screen perforation (mm): > 6 Approx. weight (kg): 700 Fjdjt Aagaspfx Akhspk Feed opening (mm): 380 x 450 Feed opening option, M Version (mm): 295 x 450

Condition: new, Year of construction: 2026, functionality: fully functional, machine/vehicle number: TH GST 4060 2411 001, overall weight: 1,650 kg, rotor diameter: 400 mm, number of blades: 6, rotor width: 600 mm, power: 22 kW (29.91 HP), The compact inline granulators of the GST series are designed for use in injection molding and blow molding operations. They are suitable for recycling, for example, bulky parts such as bottles, canisters, crates, sprues, and injection-molded parts. Thanks to their low feed height, the machines can be easily loaded by hand or with a small conveyor belt. Low noise emissions and minimal space requirements make the GST series the perfect solution for inline size reduction. All GST series machines feature a compact, sound-insulated machine housing and a noise-dampened feed hopper. The feed hopper can be opened and closed via a gas pressure damper. The compact granulators are available with two rotor diameters (250 mm, 400 mm) and rotor widths from 300 up to 1000 mm. Smaller machines come with an open F-rotor, while the larger models are equipped with the heavier S-rotor. The curved rear wall of the cutting chamber ensures aggressive material intake and prevents blockages. Thanks to the modular construction of the granulator, it can be easily upgraded with additional options such as replaceable wear plates. As with all ZERMA granulators, rotor and stator knives can be adjusted outside of the machine, significantly reducing downtime during maintenance. An adjustment gauge is included in the standard delivery. The control cabinet is mounted externally on the noise protection enclosure, and all wiring is routed internally within the unit.

The rotor is driven directly by a gear motor. The low rotor speed ensures a pleasant noise level and a high-quality product. The special rotor blades can be resharpened several times, eliminating the need for complex adjustment work. The mills are fed via a noise-reducing sandwich-type hopper. Depending on the task, the machines can be equipped with various hopper variants. Low and high base frames are available as options. The ground material is either vacuumed or filled into bags or a plastic container. Good accessibility for simple and quick maintenance work is ensured by the Quick Snap locking system.
