List of products by brand ZERMA

Zerma recycling machinery and granulators

At Gester we offer second-hand Zerma machinery, one of the best-known brands worldwide in size-reduction equipment for plastic recycling and other industrial materials such as rubber, wood or solid waste. Zerma machines are robust, reliable and designed for continuous operation, making them an ideal core element in almost any processing or recycling line.

Whether you run a plastics recycling plant, a waste-recovery facility or an industrial line that generates offcuts and rejects, Zerma granulators and shredders allow you to feed extruders, washing lines, pelletizing systems or compactors with a consistent, well-defined regrind.

Why choose used Zerma equipment

Powerful and stable size reduction: Zerma granulators and shredders are engineered to handle bulky parts, technical plastics, sprues, purges and high-strength materials without losing cutting quality. Their cutting chambers and rotor designs help deliver a homogeneous particle size, which is essential for improving efficiency in the downstream stages of washing, separation and extrusion. Uniform regrind reduces blockages, stabilises throughput and makes process settings easier and more repeatable.

Heavy-duty construction for intensive use: Zerma equipment features solid grinding chambers, dynamically balanced rotors and long-life blades manufactured from high-resistance steels. This robust design supports extended production runs with fewer unplanned stops and fewer blade changes. In plants operating multiple shifts, this translates into lower maintenance costs and higher overall availability of the recycling line.

Easy integration into recycling lines: Zerma machines can be configured as primary shredders, secondary granulators or intermediate size-reduction stations in mechanical recycling processes. Infeed openings, rotor layout and screen options make it easier to adapt the equipment to existing lines with extrusion, washing, density separation or pelletizing, often with minimal layout changes.

In addition, the wide Zerma range means you can select the right solution for each stage of the process: from hopper-fed shredders to beside-the-press granulators, units with conveyor infeed, extraction fans or big-bag discharge systems.

Zerma solutions available

In our second-hand catalogue you will find Zerma granulators, shredders, multi-shaft machines and auxiliary equipment, all inspected and ready to work from day one. We can offer solutions for light plastics, technical materials, thick or bulky parts, sprues, purges, profiles, sheets and a wide range of post-consumer and post-industrial waste.

Depending on your production requirements, it is possible to choose low-, medium- or high-throughput models, with different rotor geometries, blade sets, screen types and feeding systems. Many of these machines can be combined with belt conveyors, cyclones, extraction fans or storage hoppers to integrate them into a complete recycling line.

Every used Zerma unit supplied by Gester undergoes a mechanical inspection and functional check, so it can be installed in your plant with minimal downtime and at a much lower cost than a brand-new machine.

Ask for current availability

If you are looking for used industrial recycling machinery specialised in size reduction, granulators, shredders and plastic recycling processes, we can help you select the Zerma equipment that best fits your plant. We analyse the material type, required throughput, target particle size and available floor space to propose the most suitable configuration for your process.

Get in touch with us to check the current availability of Zerma machines and to study how to integrate them into your recycling line, either as your main grinding system or as additional capacity to increase overall production.
