Main Products
SLOWSPEED GRANULATOR GSL 180
The GSL 180 Slow Speed Granulator is designed for efficient, low-noise and low-dust grinding of plastic runners, sprues and rejected products. Its direct-drive geared motor and staggered rotor provide reliable granulation with easy knife sharpening and maintenance. Available with various hopper and base frame configurations, it integrates easily with injection and blow molding machines or robots. The resulting granules can be immediately reintroduced into production, supporting efficient inline recycling and material recovery.
SLOWSPEED GRANULATOR GSL 300
The GSL 300 Slow Speed Granulator delivers quiet, low-dust grinding for runners, sprues, rejected products and thicker plastic materials. Its directly driven, staggered 300 mm rotor provides reliable performance for injection and blow molding applications, while specially designed knives simplify sharpening and maintenance. Available with various hoppers, base frames and optional blower systems, it can operate beside molding machines or as a low-noise central granulator for small throughput requirements. Click to watch.

The GSL Series is suitable for plastics processing industries, particularly injection and blow molding applications. It is used to grind runners, sprues, rejected parts and production waste for immediate recycling. Its low-speed operation provides low noise and dust, making it ideal for production environments requiring efficient, clean and reliable material recovery.
GSE SERIES
The GSE Series is suitable for the plastics processing industry, including injection molding, blow molding, extrusion and recycling applications. It efficiently processes runners, sprues, rejected parts and plastic production waste. Designed for reliable size reduction, the GSE Series supports material recovery, waste reduction and efficient reintroduction of regrind into production processes.
GSC SERIES
The GSC Series features specialized cutting geometry designed to efficiently process large and voluminous plastic materials. It is suitable for applications involving bulky parts, production waste, runners and rejected products, providing reliable size reduction. The series supports efficient plastic recycling and material recovery across injection molding, blow molding and general recycling operations.
Components and Functionalities
SCREENS
The screen controls the final particle size of granulated material. Its perforated surface allows correctly sized particles to pass through while retaining larger pieces for further cutting. The screen frame and mounting system ensure secure positioning and easy replacement. Selecting the correct screen size improves throughput, consistency and granulator performance.
FORCE FEEDER
The Force Feeder increases the throughput of ZERMA GSH granulators when processing loose and bulky materials such as plastic bottles. It actively pushes material into the cutting chamber, ensuring a more consistent feed rate and improving granulation efficiency. This system is particularly useful for handling lightweight, voluminous plastic waste.
GRANULATOR BLADES
Granulator blades are essential for efficient and economical size reduction. Sharp blades provide clean, consistent cutting while reducing energy consumption and machine load. Proper blade maintenance helps maintain high throughput, consistent granulate size and reliable performance, while reducing wear and operating costs.
