The Zellner brand specialises in the supply and installation of various types of shredders, mills, comprehensive crushing as well as washing recycling systems. Our machines help efficiently process plastics, wood, metals, and other materials with a focus on performance, long service life, and low operating costs. Thanks to modern technologies, we deliver reliable solutions for industrial recycling and sustainable production.
Each Zellner product line is designed to meet the specific requirements of different industries. From compact machines for smaller operations to robust industrial lines – we offer solutions that save energy, increase productivity, and support the circular economy.
Zellner shredders are more than just machines – they are reliable partners for any operation where waste materials need to be turned into valuable resources. Thanks to smart engineering, they deliver consistent performance even under long-term load, allowing you to process larger volumes of material without unnecessary downtime. The robust steel construction and high-quality blades ensure long service life, while easy operation and simple maintenance save both time and costs. With Zellner shredders, you gain the assurance that your recycling process will be fast, efficient, and cost-effective.
Zellner granulators take recycling to the next level. Precise and consistent granulation allows you to obtain material with the ideal particle size, significantly increasing its value for further processing. Our technology is designed to reduce energy consumption while maximising performance – meaning lower operating costs and higher return on investment. Thanks to their compact and modular design, the granulators can be easily integrated into existing lines and adapted to your specific needs. With us, you transform waste into a valuable resource and gain a competitive advantage.
Complete Zellner recycling systems are synonymous with modern, environmentally responsible production. We combine state-of-the-art shredders, granulators, and complementary technologies into integrated lines that operate automatically, efficiently, and with minimal energy consumption. Each solution is tailored to customer requirements – whether for plastics, wood, metals, or other industrial waste. With our systems, you gain not only technology but also a strategic partner who helps you reduce costs, increase productivity, and strengthen your company’s image as a leader in sustainability.
Zellner shredders are designed for reliable and consistent processing of a wide range of materials – from plastics and wood to metals. They are characterised by high performance, easy maintenance, and a robust construction that withstands even the most demanding operations.
ZV Series Single Shaft Shredders are small - medium size reduction machines suitable for processing a wide range of materials to a uniform particle size. The output products created can often be sold as is, or be sent for further processing through additional equipment (granulators briquetters etc). Throughputs typically range between 300kg/hr – 5,000kg/hr+ depending on the machine model, material type, screen size and application.
ZK Series Single Shaft Shredders are heavy duty machines suitable for processing a wide range of materials. This range of shredders are ideal for the size reduction of flexible and/or medium hard voluminous products often loaded in bales. The fast acting, PLC controlled swing pusher automatically forces material to the rotor according to motor loading, maximising material throughput. Machine capacities typically range between 1,500kg/hr –9,000kg/hr+ depending on the model, maximising material type and application.
Low speed, high torque operation minimises noise and power consumption, whilst achieving high throughput rates. These machines are particularly suited to the size reduction of bulky or voluminous materials which could include contamination such as metals or stones.
ZX Series Twin Shaft Shredders are extremely high torque, high throughput, rotating shear type size reduction machines often used for pre-shredding of large volume or high strength materials which may contain contamination. The unique modular split chamber design, provides excellent access to key components therefore reducing maintenance downtime and service costs.
ZZ series vertical shredders are mostly recommended for applications processing pre-shredded metal scrap from twin shaft shredding systems. These machines aggressively size reduce and densify pre-shredded material whilst liberating the various different fractions, allowing for better separations and reduced transportation costs.
ZYS series pre-shredders are designed for processing high strength and tough materials with high levels of contamination. The machine pre-shreds compressed and baled material into fractions for further processing. Film type materials are opened up to enable effective cleaning and washing.
Zellner granulators, ensure precise processing of materials into flakes with an optimal particle size. They are ideal for further use in the recycling process or in the production of new plastic products. High efficiency and low energy consumption deliver maximum economic benefits.
ZGC Series Granulators are high speed granulation machines designed especially for the efficient size reduction of various materials in a single pass. These machines are ideal for processing a multitude of materials including plastics, rubber, fibers, copper cable and light non-ferrous metals amongst others.
ZGMC Heavy Duty Granulators are designed for high throughput size reduction of larger sized products in a single pass. These machines are specifically designed for treating plastic film or PP big bag material of high contamination. Incorporating various different methods of wear protection such as replaceable wear plates and resistant surface coatings, the ZGMC machines are well suited to processing abrasive, contaminated materials such as glass filled plastics and dirty films containing sand particles.
ZGXC Series Heavy Duty Granulators with power ratings of 55kw to 315kw are designed for high throughput processing. With a variety of rotor configurations available, these granulators have a wide range of applications including; hollow and voluminous materials (i.e. plastic barrels, crates and chairs), flexible materials such as films, woven bags and rubber, tougher materials such as profiles, thick sheets, and other general plastics.
Comprehensive Zellner recycling systems integrate pre-shredders, shredders, granulators, magnetic metal separators, eddy current separators, conveyors, dedusting units, and other complementary technologies, including washing technologies, into fully automated lines. They enable efficient sorting and processing of waste materials on the way to their transformation into raw input for further industrial use, representing a modern path toward sustainable and environmentally responsible production.
