Cutting Mill

Zerma GST 400/600

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.
