Kitech Machinery KSP Series Pelletizing Machine Test: Advanced Single-Screw Granulation Solution for Low-MFI HDPE Recycling
A specialized pelletizing solution from Kitech Machinery has recently been validated by a South Korean industrial client for recycling high-density polyethylene (HDPE) flakes. Designed to handle materials with ultra-low melt flow rates, the KSP Series Single-Screw Low-Temperature Granulation System demonstrated exceptional performance during on-site acceptance trials, converting post-industrial plastic waste into premium reusable pellets through an optimized recycling workflow.
System Capabilities
Engineered for rigid polymer recovery, the KSP Series integrates material handling, extrusion, purification, and finishing technologies into a closed-loop platform compatible with PP, PE, HDPE, ABS, PS, HIPS, and PC regrind. The system’s low-temperature processing preserves material integrity while achieving industrial-scale outputs, enabling direct reuse of recycled pellets in manufacturing applications.
Core Technical Components
1.Precision Feeding Module
A corrosion-resistant screw feeder with integrated magnetic separation ensures contamination-free material transfer to the extrusion unit. Customizable feed rates align with production demands while protecting downstream equipment from metallic particulates.
2.Enhanced Single-Screw Extrusion Unit
Featuring an innovative screw geometry and wear-resistant metallurgy, this component delivers 20% greater throughput than conventional designs with 150% extended operational lifespan. Optimized for materials with poor flow characteristics (MFI 0.15g/10min), it maintains stable processing of HDPE flakes without thermal degradation.
3.Multi-Stage Purification
Twin vacuum degassing stations systematically remove volatiles and moisture, achieving final pellet moisture content below 0.1%. Coupled with a precision temperature management system (180-190°C operating range), this ensures material properties remain intact during phase transition.
4. High-Capacity Filtration
A piston-style screen changer with expanded filtration area maintains continuous operation through efficient contaminant removal. Enhanced sealing technology eliminates leakage, while integrated static mixing enhances melt homogeneity.
5. Adaptive Pellet Formation
A European-designed cutting system with frequency-regulated motors produces uniform pellets (±0.5mm tolerance). Anti-adhesion water circulation prevents material buildup during continuous operation.
6. Intelligent Process Control
Siemens PLC-based automation enables single-touch operation with formula memory for multi-material processing. Integrated safety interlocks and real-time monitoring ensure consistent output quality across production batches.
7. Performance Highlights
Recent trials with HDPE scrap demonstrated sustained throughput of 400-500 kg/h at 15-18% reduced energy consumption versus industry standards. Output pellets exhibited uniform MFI values and chromatic stability, meeting stringent Grade-A reuse specifications for injection molding and extrusion applications.
8. Sustainable Pellets Storage
The system’s closed-loop water chilling system minimizes thermal energy waste, while its multi-stage drying architecture achieves residual moisture levels ≤0.05%. Dual-hopper storage with 150% capacity enhancement supports continuous packaging operations with real-time output tracking.
