Single shaft shredder

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, voluminous parts such as bottles, canisters, crates, sprues, and molded parts. Thanks to the low feed height, the machines can be easily loaded by hand or with a small conveyor belt. The low noise emissions and space requirements make the GST series the ideal solution for inline size reduction.

All GST series machines feature a compact, soundproofed housing and a noise-insulated feed hopper. The feed hopper can be tilted open and closed via a gas strut. The compact granulators are available with two rotor diameters (250 mm, 400 mm) and rotor widths from 300 to 1000 mm. The smaller models feature an open F-rotor, while the larger machines come equipped with the heavier S-rotor. The curved rear wall of the cutting chamber ensures aggressive material intake and prevents material blockages. Thanks to the modular design, the granulator 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 the machine to minimize downtime during maintenance. A setting gauge is included in the delivery. The control cabinet is mounted externally on the noise protection enclosure, with internal wiring throughout the system.
