Injection Moulding Film & Thermo Forming Blow Moulding Extrusion Roto Moulding General Recycling Post Consumer Recycling
Extrusion
Pipe and profile extrusion is defined as a process of forcing the polymer melt through a shaping die. The extrudate from the die is sized, cooled and the formed pipe is pulled to the winder or a cut off device. Prior to this, the plastic material in the form of polymer granules is fed into the hopper, conveyed by a rotating screw through a long cylindrical barrel. This is subjected simultaneously to high temperature and pressure, forcing the melt through the die at a predetermined rate. After PVC, PE is the most widely used thermoplastic piping material.
Typical challenges in recycling
The main challenge lies in the length of the extruded products, commonly pipes and profiles are metered off at 6m length. ZERMA offers a solution for for all parts accumulated during extrusion processes.

For thin walled PVC pipe and profiles the GSP pipe and profile granulators provide a single step solution. Due to their low feeding height these granulators are especially well suited for the grinding of long parts such as window profiles or small diameter pipes. Even at lengths of more than 6 m these parts can be fed easily into the almost horizontal hopper.

For pre-cut pipes of medium diameter the granulators in the GSH series are a one step solution, here the machines are equipped with a special pipe hopper ensuring that the pipes are entering the rotor at an optimal angle for best results. Alternatively these pipes can be processed in a two step shredder/granulator combination as well.

The best recycling solution for large diameter pipes and profiles are the ZERMA ZRS shredders specifically designed for this task, in these shredders pipes of up to 1200 mm diameter and 6 m length can be processed safely and efficiently.

To create PVC powder from the ground pipes or profiles the Pulverizers of the PM series can be used.

GSL Slow Speed Granulators
The slow speed granulators in the GSL range are mainly used in injection and blow moulding processes as beside the press machines to grind runners and sprues. The machines 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 machine with most types of injection moulding machines and robots.

GSE Economical Granulators
The GSE series of machines are designed as economical granulators for in-house recycling. The aggressive tangential in-feed 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 granulators 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.

GSH Heavy Duty Granulators
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.

GSP Pipe/Profile Granulators
Conventional granulators have substantial problems handling long pipes and profiles. 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.

GRF Roller Feed Granulators
The granulators in the GRF series are based on the proven GSC series of machines. They are fitted with roller feeding devices specifically designed for the recycling of edge trim from sheet extrusion or skeletal waste in thermoforming applications. The compact soundproofed design allows these machines to be used inline where the regrind can be reintroduced into the production process immediately.

ZBS Small Lump Shredders
The ZBS shredders have been designed for in house recycling of small lumps and purges from injection and blow moulding 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 re introduced into the production process immediately.

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.

PM Disc Pulverizers
The main purpose for the ZERMA PM Pulverizers is the pulverization of PVC regrind in pipe and profile recycling. Working in line with a shredder and granulator to have a balanced and efficient system to handle in house production waste. Another application is the grinding of PE for Roto Moulding applications where the PM Pulverizer is used to create powder required in the production process.

ZHM Hammer Mills
The main purpose for the ZERMA ZHM hammer mill is the processing of electronic waste, such as whole computers, white goods and ICBs. The main advantage in these processes lies in its insensitivity to contamination and abrasive materials while being able to achieve a rather small output material. Through the high degree of disintegration it is possible to achieve good separation results in the following processes.
