Wanner Dynamic Series Granulation Machines
Powerful, Robust and Flexible Grinding Solutions for Large Parts and High-Volume Sprues
Wanner Dynamic Series granulation machines are professional shredding solutions designed specifically for applications involving large-sized parts, bulky sprues, and high material throughput requirements. Developed and manufactured in Germany, the Dynamic Series features a robust and long-lasting construction that can be safely used both next to injection molding machines and within centralized recycling systems.
The core design philosophy of the Dynamic Series focuses on maximum mechanical strength, high shredding capacity, and stable granulate quality even when processing demanding plastic materials. The series is engineered to handle a wide range of materials, from soft plastics to rigid and glass-fiber-reinforced compounds, with consistent and reliable performance.
General Technical Design and Operating Principle
Wanner Dynamic granulators stand out with their zigzag (chevron) cutting geometry rotor design. This special cutting geometry ensures continuous material engagement on the rotor, delivering homogeneous grinding performance even under irregular feeding conditions. Large and thick-walled parts are broken down in a controlled manner, resulting in high-quality regrind.
The machine housing and cutting chamber are equipped with wear-resistant, hardened components. This enables the Dynamic Series to operate reliably over long periods, even when processing abrasive materials such as plastics with high glass fiber content. The rigid machine frame minimizes vibration and helps maintain precise machine settings throughout many years of operation.
Dynamic Series Model Options and Technical Data
The Dynamic Series is available in various models to meet different capacity and application requirements.
D 25.25 Model
Cutting chamber opening: 250 x 255 mm
Rotor diameter: 180 mm
Number of rotor knives: 12
Number of stator knives: 2
Motor power: 4 / 5.5 / 7.5 kW
Machine weight: approx. 360 kg
This model provides an ideal solution for medium-sized sprues and parts and is well suited for beside-the-press applications.
D 25.38 Model
Cutting chamber opening: 250 x 385 mm
Rotor diameter: 180 mm
Number of rotor knives: 18
Number of stator knives: 2
Motor power: 5.5 / 7.5 kW
Machine weight: approx. 410 kg
The D 25.38 model is preferred for processing larger and bulkier sprues. The belt-driven version is particularly suitable for high-throughput applications.
D 25.50 Model
Cutting chamber opening: 250 x 505 mm
Rotor diameter: 180 mm
Number of rotor knives: 24
Number of stator knives: 2
Motor power: 5.5 / 7.5 kW
Machine weight: approx. 480 kg
This model enables safe and efficient granulation of long and bulky parts.
D 30.50 Model
Cutting chamber opening: 300 x 500 mm
Rotor diameter: 250 mm
Number of rotor knives: 6
Number of stator knives: 2
Motor power: 7.5 kW
Machine weight: approx. 570 kg
The D 30.50 is specifically designed for large, thin-walled blow-molded products and very bulky parts. Its large rotor diameter ensures fast and reliable intake of lightweight but voluminous components.
Compact Versions
The Dynamic Series is also available in compact versions such as D 25.38 comp and D 25.50 comp, featuring low rotor speed and geared motor drive. These models occupy less space when installed beside the press and provide an ideal solution for processing bulky sprues.
Noise Control and Optional Sound Insulation
Dynamic Series granulators minimize vibration through their rigid machine design as standard. Depending on requirements, integrated sound insulation hoods or fully enclosed versions can be supplied. These solutions significantly reduce noise levels while improving occupational safety and operator comfort in production environments.
Energy Efficiency and Intelligent Control Systems
The Dynamic Series can be equipped with Green Line and IQ Line energy-saving control systems.
The Green Line system uses an automatic start-stop function, ensuring the granulator operates only when required and eliminating idle running times. Energy savings of up to 70 percent can be achieved.
The IQ Line system features frequency inverter control, allowing the rotor speed to be adjusted according to process requirements. Energy consumption can be reduced almost proportionally to speed reduction. Thanks to the OPC-UA interface, energy consumption, operating times, and maintenance data can be monitored digitally.
Modular Design and Application Flexibility
Wanner Dynamic Series machines can be configured with a wide range of options, including various feed hoppers, mobile stands, conveyor belt feeding solutions, dust extraction systems, fan and cyclone integrations. Special hopper designs are available for long profiles, sheets, film strips, and blow-molded products.
In centralized granulation stations, Dynamic Series machines can be integrated with fans, cyclones, metal separators, and dust extraction systems to create professional solutions capable of processing more than one ton per shift.
Ease of Maintenance and Long Service Life
Dynamic Series granulators feature tool-free opening cutting chambers and large access doors, making maintenance and cleaning extremely easy. Wear-resistant cutting components ensure long-term stable performance and help reduce the total cost of ownership.
Conclusion
Wanner Dynamic Series granulation machines are robust, reliable, and flexible recycling solutions developed for large parts, bulky sprues, and high-capacity production requirements. With their modular design, high shredding capacity, and long service life, they represent a professional investment for both beside-the-press and centralized recycling applications.
