ZERMA, founded in 1941 and headquartered in Germany, specializes in the development and manufacturing of devices for plastic crushers and shredders. Among the countries where ZERMA operates is Malaysia. The company offers a comprehensive range of size reduction technology, spanning from beside-the-press shredders to large heavy-duty shredders, including compact sound-proofed granulators and specialized systems for in-house size reduction, large diameter pipes, and tires.
The foundation of ZERMA's technology lies in well-trained engineers guided by an experienced international team. They utilize cutting-edge 3D modeling software for designing and improving machines, while production is managed with a state-of-the-art ERP system. Continuous feedback from customers and agents worldwide contributes to the enhancement of ZERMA's size reduction technology and the identification of new market trends.
The slow speed granulators model GSL 180 range feature a staggered 180 mm diameter rotor with widths ranging from 180 to 430 mm. The rotor is directly driven by a geared motor. The low rotor speed reduces the noise level of the machine and creates less dust while crushing. The GSL series' distinctive design blades are easily sharpenable and do not require subsequent adjustment. The material is delivered through a sound-absorbing feed hopper that can be customised to match a variety of applications and feeding methods. Depending on the requirements the machines can be fitted with a wide variety of hoppers, they are mounted on either low or high level base frames with matching suction bins or bag filling adapters. Quick snap fasteners and hand screws make access to the machine for cleaning and maintenance fast and easy.
The slow speed granulators model GSL 300 range feature a staggered 300 mm diameter rotor with widths ranging from 400 to 800 mm. The rotor is directly driven by a geared motor. The low rotor speed reduces the noise level of the machine and creates less dust while grinding. The special design knives of the GSL series can be sharpened easily and do not need adjustment afterwards. The material is delivered through a sound-absorbing feed hopper that can be customised to match a variety of applications and feeding methods. Depending on the application, the machines can be equipped with a wide range of hoppers and installed on either low or high level base frames with matching suction bins or bag filling adapters. Quick snap fasteners and hand screws provide for quick and easy access to the machine for cleaning and maintenance.
For the GSE 300 series different rotor designs are available in widths ranging from 300 mm to 1400 mm with a diameter of 300 mm. The completely welded cutting chamber in conjunction with the "V" type rotor design ensures dependability in operation and universal application use. The housing design offers easy and quick access to the cutting chamber during rotor and stator knife changes, servicing or screen changes
The GSL slow speed shredders of the 300 series are mainly used in injection and blow molding processes as beside the press machines to grind runners and sprues. But they can be used as low noise central size reductors for small throughput requirements as well. The stronger design of the 300 series GSLs allow them to be used for stronger and thicker materials while offering the same advantages regarding low noise and dust as the smaller GSL machines. All GSL models can be equipped with a built in blower system in case a vacuum loading system is not available, or to transport the ground material to bags for storage.
The GSE series of machines are designed as economical crusher for use in medium volume in-house recycling applications. The cutting geometry of the GSE 500 series allows even bigger hollow parts to be shred. 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 cutting geometry of the GSC series allows even voluminous materials to be ground. The complete GSC series 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 700 series GSC machines are mainly used as central granulators for processing of large injected or blow moulded products as well as film. 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 right screen size can make a big difference in the performance of a machine, and sometimes you just need a new screen fast. Most standard screen sizes are available in stock, or can be manufactured quickly. This includes screens made from wear resistant materials or stainless steel.
To increase the throughput of the ZERMA GSH granulators when used with loose materials such as bottles, we developed the force feeding system. This system forces the feeding material into the cutting chamber and avoids the common problem of material 'dancing' on the rotor. Adding one of these force feeders increases the throughput greatly. The force feeders are available in two basic designs: Screw and paddle type.
A shredder performs best and most economical when the blade is sharp. Regular knife changes and correct setting of the cutting gap help ensure a good final result and reduced power consumption. We keep blades in stock, as do our subsidiaries and agencies all over the world to supply you with a fresh blade whenever you need it.
