The slow-speed beside-the-press granulators of the GSL series are mainly used in injection moulding and blow moulding applications for inline granulation of sprues and defective parts. Thanks to various hopper and extraction systems, these machines can be flexibly integrated into existing installations.

GSL 180: For granulating sprues from injection moulding and blow moulding operations.

Key features of the GSL series:

- Low noise operation due to low rotor speed, inclined cutting, and a soundproofed multi-layer sandwich hopper
- Powerful and efficient drive thanks to branded gearbox
- Easy maintenance, cleaning, and knife change

The slow-speed beside-the-press granulators of the GSL 180 range feature a closed rotor with a diameter of 180 mm. Working widths from 120 mm to 430 mm are available.
The rotor is composed of individual discs, which are directly connected to the spur gear via an oversized drive shaft, enabling efficient and low-maintenance power transmission.

Material to be granulated can be fed manually, via conveyor belt, or by robot through a generously dimensioned, soundproofed hopper (sandwich design). As standard, the granulator is mounted on a low base frame on swivel castors. Material discharge is via a suction bin located under the screen, with a pipe connection for a vacuum conveyor.

Applications

The slow-speed beside-the-press granulators of the GSL 180 series are specifically designed for the size reduction of sprues in injection moulding and blow moulding processes. Easy accessibility allows for quick colour and material changes. The low rotor speed also permits processing both soft and hard materials, ensuring good material quality with minimal dust content.
