Slow Speed Granulators YEARS The Home of Size Reduction

Granulators designed for inline applications The low speed granulators of the GSL series are designed to recycle rejects and scrap in injection and blow molding applications. Various hopper and discharge designs allow a flexible and customised implementation of the machines. GSL series key characteristics: y Low noise due to the low rotor speed, staggered rotor blades and sound dampening hopper in sandwich construction y Powerful efficient power transmission using high quality geared motors y Simple maintenance, cleaning and blade change

Application Examples Injection molding GSL beside-the-press granulators are used to grind sprues or reject parts directly at the injection molding machine. The resulting regrind can be immediately reintroduced into the production process. Customer and application specific solutions Due to the modular design of the machines the hopper and discharge can be customised according to specific requirements. Allowing for direct feeding without conveyors or robots. Mobile grinding solution Optional accessories The granulators are mounted on heavy-duty casters to allow for flexible placement and easy...

Our beside-the-press granulators Easy maintenance and cleaning The slow-speed granulators of the GSL series operate at a low rotor rpm ensuring a minimal noise level and the highest quality virtually dust free regrind. Access to the cutting chamber and screen is quick and easy without the need for tools. The specially designed rotor knives can be resharpened several times and due to their unique design do not require any adjustment when installing in the granulator after sharpening. Seals and high precision manufacturing ensure a clean machine environment. Safety All machines are designed...

GSL180 Series The slow speed granulators of the GSL180 series feature a closed 180 mm diameter rotor with width range options from 120 mm to 430 mm. The rotors are comprised of single discs arranged on an oversized drive shaft connected to the gear motor. This allows for efficient and low maintenance power transmission. The material can be fed manually, by conveyor or by robot into the large sound dampening hopper. Typically the machines are placed on a low frame with integrated heavy duty casters. Discharge of the material is accomplished via vacuum system from the integrated stainless...

GSL 300 series The slow speed granulators in the 300 series feature a 300 mm diameter rotor with widths ranging from 400 mm - 800 mm. The rotor is directly driven by a geared motor. This ensures smooth operation even when processing challenging materials. The low rotor speed generates less noise and a high quality, low dust regrind. The specifically designed rotor knives can be sharpened multiple times and can be installed in the machine without readjustment of the cutting system. The Quick-Snap system and large knobs allow fast and easy access to the cutting chamber without the need for...

Well considered and efficient – Details Unique knife design simplifies maintenance The rotor is equipped with specially designed knives. The curvature of the knives ensures a constant cutting gap even after sharpening without the need to readjust the rotor knives. Sound dampening hopper All GSL granulators are equipped with lightweight sound dampening hoppers featuring sandwich construction of a thick layer of sound dampening material between the inner stainless steel and external aluminium. The standard hoppers allow feeding by hand or robot. Sturdy rotor The rotor shaft is supported on...

Quality is not optional! High quality components Drive system and controls are comprised of high quality name brand components to ensure a long service life plus worldwide service coverage plus compliance with safety regulations around the globe. Compact mobile design The granulators in the 180 series are designed as very compact units. Combined with the heavy duty wheels this allows for flexible placement. They can be moved around easily during tool change and maintenance on the injection molding machines. Sound proofing High-frame option Optionally the GSL granulators can be equipped with...
