Slow Speed Granulator - Zerma GSL Series

The GSL series of slow speed granulators is perfectly suited to be placed next to injection and blow molding machines for efficiently grinding runners, sprues, and rejected products.

Available in two models, the GSL 180 and GSL 300, these granulators serve as either central or beside-the-press solutions, compatible with a diverse array of materials.

GSL 180 Granulator Details

The slow speed granulators from the GSL 180 line are especially designed for use in injection and blow molding applications, adeptly processing runners and sprues.

With a staggered rotor of 180mm in diameter and widths ranging from 180 to 430 mm, these granulators can also effectively work with rejected materials during inline recycling processes, alongside various other applications.

Materials are introduced to the granulator through a sound-absorbing feed hopper, followed by processing within the cutting chamber; the resulting granules can be seamlessly reintegrated into the production flow.

While operating, the low rotor speed of the GSL 180 granulator ensures lower noise levels and generates minimal dust during grinding.

Offering multiple hopper and base frame configurations, the GSL 180 can easily integrate with most injection molding machines and robotic setups.

GSL 300 Granulator Insights

Similarly designed for efficient operation, the slow speed granulators in the GSL 300 series match the capabilities of the GSL 180 and excel in all the same applications.

However, their reinforced structure and larger rotor make them ideal for handling tougher and thicker materials as low noise central granulators, suitable for smaller throughput needs.

Featuring a staggered rotor with a diameter of 300 mm and widths between 400 to 800 mm, these granulators operate similarly to the GSL 180, ensuring reduced dust and noise through a low-speed rotor.

FlexiSPEED - Optimize and Save Energy

The potentiometer on the panel enables easy adjustment of the rotor speed by ±40% (15-35 rpm), allowing for optimal regrind quality tailored to each granulation run.

Lower speeds are preferable for handling brittle materials, subsequently reducing noise levels and energy consumption.

Conversely, higher speeds are appropriate for softer materials or higher capacity situations.

Rapid QRR (Quick Rotor Release)

The Rapid QRR feature facilitates complete access to the granulator housing and rotor disconnection in around 30 seconds. This quick access is ideal for cleaning and maintenance tasks, ensuring no guesswork is needed about the granulator's cleanliness.

The gas spring aids in the opening and closing of the cutterhouse, enabling straightforward operation while ensuring safety during closing of the heavy housing.

Straight Cut with Offset Segments

The straight knife rows significantly enhance the grip on sprues and products, promoting efficient cutting and minimizing dust and fine particles that can disrupt the process.

These "teeth" are designed to be square to produce a uniform high-quality regrind, while the staggered rotor segments provide a smoother cut and reduced energy usage.
