Slow Speed Granulator - Zerma GSL Series

Slow speed granulators in the GSL series are ideal beside the press machines for use in injection and blow moulding to grind runners, sprues and rejected products.

With two available models, the GSL 180 and GSL 300, these granulators can be used as either central or beside-the-press granulators, for use with a wide range of materials.

Slow speed granulators in the GSL 180 range are mainly used in injection and blow molding processes as beside the press machines to grind runners and sprues.

Featuring a staggered 180mm diameter rotor with widths ranging from 180 to 430 mm, the granulators in this range can also be suited for use with rejected products in the inline recycling process, as well as a range of other applications.

Materials are fed into the granulator via a sound absorbing feed hopper before processing in the cutting chamber; resulting granules can then be reintroduced back into the production process.

During the operation of the machine, the low rotor speed of the GSL 180 granulator reduces the noise level of the machine whilst also creating minimal dust when grinding.

With different hopper and base frame options available, the GSL 180 can be easily integrated with most injection moulding machines and robots.

Slow speed granulators in the GSL 300 range feature similar machine benefits to those of the GSL 180, and are ideal for use in all of the same applications.

However, their stronger design and larger rotor also makes them suitable for use with harder and thicker materials as low noise central granulators, for small throughput requirements.

Featuring a staggered 300 mm diameter rotor with widths ranging from 400 to 800 mm, these granulators are operated in the same way as the GSL 180, with reduced dust and noise levels thanks to the low speed rotor.

FlexiSPEED &#; Optimize and save energy

With the potentiometer on the panel, you can easily change the rotor speed ± by 40% (15-35 rpm) to get the best regrind quality for every granulation run.

Lower speeds &#; for brittle materials, lower noise levels and lower energy consumption.

Higher speeds &#; suitable for soft materials or when higher capacity is required.

Rapid QRR (Quick Rotor Release)

Thanks to Rapid QRR, the OneCUT can be opened completely to access the granulator housing and disconnect the rotor in about 30 sec. Quick and easy access to clean or for service and maintenance. A freely rotating rotor and full visibility of the cutterhouse means that you do not have to guess whether the granulator is clean or not.

The opening / closing of the cutterhouse is facilitated by a gas spring, which makes it easy to open and safe to close the heavy granulator housing.

Straight cut with offset segments

The straight rows of knives maximize the gripping of sprues and products. Properly gripped material enables efficient cutting and reduces dust and fine particles that affect the process negatively.

The "teeth" are square to give a uniform high-quality regrind, and the rotor segments are staggered, which gives a smoother cut and lower energy consumption.
