Product Overview
The High-Speed Die Face Pelletizer is an industrial pelletizing system designed for continuous thermoplastic recycling and compounding applications. It performs direct hot-face cutting at the die head and produces uniform pellets under stable extrusion conditions.
The system is suitable for long-term operation in recycling plants and plastic processing lines requiring stable output and consistent pellet quality.
Working Principle & Engineering Design
Molten polymer is extruded through a die plate and cut immediately at the die face by a high-speed rotating cutter synchronized with extrusion flow.
Key engineering controls include:
- Stable melt distribution at die head
- Synchronized cutting speed with extrusion output
- Thermal stability control in cutting zone
Two configurations are available depending on material characteristics:
Water-ring pelletizing system for standard thermoplastics
Air-cooled die face system for heat-sensitive materials
Engineering Reliability & Operating Considerations
The system is engineered for stable industrial operation. Common operational challenges are addressed through design:
- Material sticking at die face → thermal zoning control
- Uneven pellet size → precision blade alignment system
- Blade wear imbalance → wear-resistant rotor structure
- Temperature fluctuation → closed-loop thermal control system
- Melt leakage → reinforced sealing design
Key Features
- Direct die-face cutting system
- Continuous and stable pellet production
- Modular cutting chamber for easy maintenance
- PLC synchronized control system
- Compatible with PP, PE, ABS, PS, PET and engineering plastics
- Reduced fines and improved pellet consistency
