ZERMA Machinery Thailand Europe GmbH, ZMT Europe for short, is responsible for the sale of ZERMA slow speed granulators in Germany and Europe. Our head office is in Egestorf, near Hamburg. Since our founding a year ago, we have already sold numerous side-by-side mills in Europe.
The offered slow speed granulators are primarily used in plastics processing companies. The extensive program of slow speed granulators of the GSL series covers a large number of applications and tasks.
Thanks to extensive stocks, all machines are available quickly. In addition, we offer spare and wear parts to ensure that the side mills are always ready for use.
Our service also includes training and commissioning. In addition, we offer support with the routine maintenance of the slow speed granulators, such as changing knives. In addition, there is the possibility of carrying out tests with customer material either on site or in our technical center.
At ZMT Europe, the focus is on offering high-quality slow speed granulators and comprehensive customer service. We remain at your disposal for any further information or to discuss specific requirements.
With more than 70 years of experience ZERMA is one of the leading producers of high quality size reduction technology, covering the whole spectrum of size reduction starting with the GSL series.
The slow 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 180 Mainly used in injection and blow molding processes as beside the press machines to grind runners and sprues
GSL 300 Can be used as low noise central granulators for small throughput requirements as well
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. 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. The material to be processed is introduced into the machine via a light-weight sound dampening hopper built in sandwich construction. The screen mounted at the bottom of the cutting chamber regulates the final size of the granulated material.
The regrind is collected in a stainless steel bin, which can be emptied with normal vacuum systems.
All machines are designed according to latest statutory safety standards to avoid operation while the cutting chamber is accessible.Easy maintenance and cleaning
Access to the cutting chamber and screen is quick and easy without the need for tools. Seals and high precision manufacturing ensure a clean machine environment.
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.
The rotor shaft is supported on both ends by heavy duty bearings. Due to the modular design of the rotor the shaft is sized for the widest machine ensuring performance and longevity across the whole range. The staggered design of the rotor means that a maximum of 2 blades cut at any one time thus reducing the stress on the rotor.
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.
The proven ZERMA quick-snap system allows a quick and easy opening of the machine and removal of the front plate to gain access to the screen. This allows simple cleaning when changing colour or material. Safety switches avoid starting of the machine when the cutting chamber or rotor are exposed.
Optionally the GSL granulators can be equipped with complete sound proofing cabin and doors to further reduce the operational noise.
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 steel material collection bin.
The slow speed granulators in the GSL180 series are specifically designed for the processing of runners, sprues and rejects in injection molding processes. The safe, easy access to the cutting chamber allows for quick changeovers in case of material or colour changes. The low rotor speed allows processing of pliable as well as rigid materials and ensures high quality regrind with low dust.
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 tools. The material is introduced into the machine via a sound dampening hopper. The machines can be customised depending on the application with different hoppers and discharge options.Applications
The slow speed GSL300 series are well suited for the processing of production scrap as well as voluminous parts. They can also be used as central granulator for low volume production or in laboratory environments. The sturdy construction and high torque of the GSL300 series allows processing of heavier, thick walled and other challenging materials.
