In the demanding cable and wire industry, producing consistent, high-quality compounds for PVC insulation/sheathing, low-smoke halogen-free (LSZH/HFFR), 10–35 kV chemically cross-linked PE (XLPE), and semi-conductive shielding materials requires exceptional mixing uniformity, precise temperature control, and outstanding energy efficiency. The RLB Two Stage Reciprocating & Single Screw Pelletizing Line (also known as the reciprocating kneader + single-screw tandem pelletizing unit) is specifically engineered to meet these challenges while delivering up to 25 % energy savings compared to conventional extruders.
This advanced two-stage system combines a high-intensity reciprocating single-screw mixer (first stage) with a low-shear single-screw extruder (second stage) connected via T-type distribution. The reciprocating motion provides powerful radial and axial mixing, short material residence time, high filler loading capacity, and superior self-cleaning performance — ensuring uniform dispersion without temperature peaks that could degrade sensitive polymers.
Key Engineering Advantages
- Superior Mixing Performance: Both radial and axial mixing action plus excellent injection of liquid additives deliver homogeneous compounds with minimal shear heat.
- Energy-Efficient Design: Proven 25 % lower power consumption than standard extruders while maintaining high throughput.
- التحكم الدقيق في درجة الحرارة: No melting temperature peaks — critical for heat-sensitive materials like LSZH and XLPE.
- High Filling Capacity & Quick Changeover: Excellent self-cleaning properties and short conversion time maximize equipment utilization and reduce downtime.
- Fully Automated System: Gravimetric weighing for granules/powders, forced feeding, and precise liquid dosing combined with MMI + PLC control for recipe storage, real-time monitoring, and simple operation.
- Flexible Downstream Options: Water-ring cutting, eccentric water-mist cutting, plus various packaging solutions (bin collecting, ton-bag, automatic weighing & bagging).
The result is high-quality, dust-free pellets with excellent flow characteristics and consistent physical properties — exactly what cable manufacturers need for high-voltage, flame-retardant, and specialty applications.
