Slow speed granulator ZERMA GSL 180

The slow-speed granulators in the ZERMA GSL range from 180/120 to 180/430 have been specially developed as slow-running grinders for applications in the injection-molding sector. The material to be granulated is fed via a sound-absorbing feed hopper that is available in a range of variants to suit the application

GSL 180/120

General description

The slow-speed granulators of this range are mounted on either low or high level baseframes, depending on application, and with suction trough/ bag fill chute to suit. With these numerous options, the slow speed granulators can be tailored to an extremely wide range of applications.

In addition to the advantages common to all slow-running grinders such as low noise characteristics and near dust-free product, GSL 180/120 to GSL 180/430 stand out due to their special knife, rotor, ‘quick-snap’ opening and good accessibility features.


The GSL slow speed granulators of the 180 series are mainly used in injection and blow molding processes as beside the press machines to grind runners and sprues.

The resulting granules are then immediately reintroduced into the production process. The machines can be used for rejected products in the inline recycling process as well.

Different hopper and base frame designs make it possible to integrate the machine with most types of injection molding machines and robots
