Wanner Energy Series Granulation Machines
Industrial Shredding Solutions for Large Parts and High-Capacity Central Recycling Applications
Wanner Energy Series granulation machines are heavy-duty industrial shredders developed for the central recycling of large-volume plastic parts, thick-walled products, and sprues generated by high-throughput production lines. Designed and manufactured in Germany, the Energy Series delivers reliable, quiet, and highly efficient granulation performance, particularly in processes with high material output such as blow molding, large injection-molded parts, and extrusion lines.
Going beyond beside-the-press applications, Energy Series machines form the core of central granulation stations. Designed for integration with fans, cyclones, metal separators, and dust extraction systems, this series supports recycling capacities ranging from several hundred kilograms per shift up to multi-ton levels.
General Technical Design and Operating Principle
Wanner Energy Series granulators feature a V-cut (chevron) rotor geometry. This special cutting design enables aggressive yet controlled material intake, allowing large and bulky parts to be captured efficiently by the rotor. As the material continuously changes direction within the cutting chamber, the result is a homogeneous, uniform, and highly repeatable granulate.
The cutting chamber is extremely rigid and durable thanks to its thick-walled steel construction, welded and bolted assembly, and a large rotor shaft supported by heavy-duty bearings. This robust design maintains dimensional stability even during long-term processing of abrasive and glass-fiber-reinforced plastics.
In Energy Series machines, the cutting chamber is mechanically decoupled from the sound insulation enclosure. Vibration-damping elements significantly reduce structure-borne noise, while the standard integrated sound enclosure ensures operator comfort and compliance with environmental noise limits in central granulation applications.
Energy Series Models and Technical Specifications
The Energy Series consists of five main models designed to meet different capacity requirements.
E 30.50
Cutting chamber opening: 300 x 500 mm
Rotor diameter: 250 mm

Rotor speed: approx. 630 rpm
Machine weight: approx. 1000 kg
The E 30.50 model is an ideal central granulation solution for large injection-molded parts and medium-sized blow-molded products.
E 35.40
Cutting chamber opening: 350 x 400 mm
Rotor diameter: 300 mm
Rotor knives: 2 x 3 or 2 x 5
Stator knives: 2
Motor power: 11 - 18.5 kW
Rotor speed: approx. 500 rpm
Machine weight: approx. 1300 kg
E 35.60
Cutting chamber opening: 350 x 600 mm
Rotor diameter: 300 mm
Rotor knives: 2 x 3 or 2 x 5
Stator knives: 2
Motor power: 18.5 kW
Rotor speed: approx. 500 rpm
Machine weight: approx. 1450 kg
These two models provide wider feed openings, enabling safe processing of long profiles, wide parts, and high-throughput production lines.
E 45.50
Cutting chamber opening: 450 x 500 mm
Rotor diameter: 400 mm
Rotor knives: 2 x 3 or 2 x 5
Stator knives: optional 3
Motor power: 18 - 30 kW
Rotor speed: approx. 450 rpm
Machine weight: approx. 1850 kg
E 45.80
Cutting chamber opening: 450 x 800 mm
Rotor diameter: 400 mm
Rotor knives: 2 x 3 or 2 x 5
Stator knives: 2
Motor power: 22 - 30 kW
Rotor speed: approx. 450 rpm
Machine weight: approx. 2200 kg
The E 45.80 is the highest-capacity model in the Energy Series and is designed for very large blow-molded parts, pallets, containers, and bulky technical components.
Integration with Central Granulation Systems
Energy Series machines are specifically engineered for central granulation stations. They can be integrated with pneumatic conveying systems, cyclone separators, rotary air locks, metal separators, and conveyor belts.
These integrated systems enable:
Granulation capacities of 500 kg/h and above
Clean separation of granulate and conveying air
Efficient dust filtration
Clean and homogeneous regrind even for glass-fiber-reinforced materials
For abrasive applications, fan and piping systems can be supplied with optional wear protection.
Noise Control and Operator Safety
Energy Series machines are supplied as standard with an integrated sound insulation enclosure. Wide-opening doors and gas-spring-assisted feed hoppers ensure fast, safe maintenance and cleaning. Integrating the fan into the sound enclosure reduces the required footprint while significantly lowering noise emissions.
Fully enclosed configurations are available as an option, allowing installation close to production areas when required.
Modular Design and Custom Applications
Wanner Energy Series machines stand out for their customer-specific engineering options, including:
Side-fed special hoppers
Feeding channels for long profiles and sheets
Conveyor belt integrations
Super-tangential cutting chambers
Three-blade or five-blade rotor configurations
These options make the Energy Series adaptable to virtually any plastic processing facility.
Ease of Maintenance and Long Service Life
In Energy Series granulators, the cutting chamber and fan section can be opened without tools, providing easy access for maintenance. The screen housing is readily accessible, and wear-protected components ensure long maintenance intervals and low spare-part costs.
This design results in a highly favorable total cost of ownership over the long term.
Conclusion
Wanner Energy Series granulation machines are quiet, robust, and high-performance industrial solutions developed for large parts, high-capacity production lines, and central recycling applications. With their modular design, powerful rotor technology, and extensive system integration options, the Energy Series represents a benchmark solution for professional plastic recycling investments.
