The name ZERMA comes from the German word zerkleinerungsmaschinen, meaning crushing machine. Since the company was founded in 1943, this has remained the company’s mission.
ZERMA has traditionally focused on the development and production of size reduction machinery for the plastics industry. However, today ZERMA has expanded into related industries such as tire recycling, e-waste and wood recycling. Their core strength lies as a machinery and component producer. As such they are an ideal partner for systems integrators and OEM projects.
With more than 70 years of experience, ZERMA is one of the leading manufacturers of high quality size reduction machinery. From the small GSL slow speed granulators to the versatile GSH heavy duty granulators including small and compact granulators with integrated blower and soundproofing. Specialized machines like the GSP pipe and profile granulators and ZERMA PM discpulverizer systems for fine grinding applications. Adding a complete line of shredders, starting with light shredders for wood applications, up to large heavy duty shredders ZERMA recycling machines range in drive power from 2.2 kW up to 200 kW and cover the whole spectrum of plastics size reduction applications.
The slow speed granulators in the GSL range are mainly used in injection and blowmolding processes as beside the press machines to grind runners and sprues. Themachines can be used for rejected products in the inline recycling process as well.Different hopper and base frame designs make it possible to integrate the machinewith most types of injection molding machines and robots.
The GSE series of machines are designed as economical granulators for in-house recycling. The aggressive tangential infeed and advanced cutting geometry of the GSE series allows bulky hollow parts to be ground. THE whole GSE granulator line achieves a high quality regrind independent of the material type or form such as injection moulded parts, blow moulded parts, profiles, sheets, film, etc.
The GSC series of compact soundproofed machines are mainly used in inline operations or as central granualtors for processing of hollow thin walled products, or runners and sprues. The integrated sound proofing makes it possible to easily place the machine in existing operations. With different rotor designs and a wide variety of options the machines can be tailored for many different applications.
The wide range of rotors and hopper styles allow the GSH machines to be tailored to almost every application in the plastic recycling field.The GSH heavy duty granulators are mainly used as central granulators for in house recycling applications to process thick walled parts in one step or as a second step granulator after a shredder to reach higher throughput rates.
Conventional granulators have substantial problems handling long pipes and profi- les. Therefore ZERMA developed the GSP range. Thanks to the almost level feeding hopper, long pieces can be fed easily. While the machine is operating there is no risk of blocking, in case of congestion no more material will be accepted by the machine. Once the grinding chamber is empty the machine will accept material again.
The ZBS shredders have been designed for in house recycling of small lumps and purges from injection and blow molding processes. The typical input materials are small and medium sized cakes such as head waste. The material can be shred to reduce the volume or processed further in a granulator to be reintroduced into the production process immediately.
The ZSS shredders have been designed for a wide array of applications and industries such as in house and general recycling, electronic waste and post consumer waste handling with a wide variety of input materials. Depending on input material and the following process the shredded material can be used directly or go into the next step of size reduction for example in a GSH granulator.
The ZIS shredders have been designed with big volume parts such as IBCs, pallets and big barrels in mind. While it can be used for in house recycling in big volume blow moulding operations it is also versatile enough to be used for general recycling in the plastic and wood industry. Like all ZERMA shredders the ZIS can be equipped with a wear package for processing of highly abrasive or filled materials.
The ZXS shredders have been designed for the most demanding and high throughput applications in recycling industries. The input materials can be all kinds of plastics, wood, paper, cardboard, e-waste, post-consumer waste, rubber, etc. in various shapes and sizes. Typical input materials are: fridges, purges, tires, pallets, bales, drums and barrels, pipes, film and so on…
The main focus of the ZRS shredders is the shredding of large diameter pipes or bundles of smaller pipes and profiles made from HDPE, PP and all kinds of PVC. Further the machines can be used for recycling of other plastic parts, such as large lumps, stacked wheelie bins and pallets. In combination with other ZERMA size reduction equipment such as granulators and pulverizers we are able to provide a complete turnkey recycling solution.
