Hard PVC Conical Twin-Screw Pelletizing Line – High‑Performance Compounding System for Rigid PVC Granules
Complete Manufacturing Solution for PVC Profile, Pipe & Injection Molding Applications
Our Hard PVC Pelletizing Line, featuring advanced conical twin‑screw extrusion technology, is a precision‑engineered compounding system designed for the high‑output production of rigid PVC granules. Producing uniform, high‑density pellets with excellent flow characteristics and consistent quality, this line is the ideal choice for manufacturers supplying raw materials for PVC profile extrusion, pipe production, injection molding, and other rigid PVC product applications.
Built as a comprehensive system comprising high‑capacity conical twin‑screw extruders, mould‑face hot‑cutting pelletizers, and automated cooling/classification units, this line ensures exceptional plasticisation, consistent pellet geometry, and reliable continuous operation – providing a complete manufacturing solution from PVC powder blending to finished granules ready for downstream processing.
Why Choose Our Hard PVC Conical Twin‑Screw Pelletizing Line?
Advanced Conical Twin‑Screw Extrusion Technology
Hard PVC pelletizing demands specialised processing equipment capable of handling PVC powder compounds with high filler content and heat‑sensitive formulations. Our line features high‑performance SJSZ series conical twin‑screw extruders specifically engineered for rigid PVC applications . The counter‑rotating conical screw design ensures:- Superior plasticisation – PVC resin, calcium carbonate, stabilisers, and additives are uniformly mixed and homogenised
- Excellent venting – effective removal of moisture and volatiles ensures flawless pellet quality
- High output capacity – models from 70kg/h up to 800kg/h to match production targets
- Broad recipe compatibility – suitable for various hard PVC and CPVC formulations
Precision Hot‑Face Die Cutting System
The heart of the pelletizing process is the mould‑face hot‑cutting system, which ensures consistent pellet geometry and high production efficiency:- Even cutting – rotating blades cut extruded strands directly at the die face for uniform pellet size (Φ3–Φ4mm)
- Superior pellet quality – produces dense, solid, and aesthetically uniform granules
- High‑efficiency air conveying – pneumatic transfer system moves pellets to cooling and classification stages without degradation
Comprehensive Cooling & Classification Downstream
The line includes integrated auxiliary equipment for complete pellet finishing:- Cyclone separator – separates pellets from conveying air
- Vibration sieve – classifies pellets by size, removing fines and oversize particles
- Air‑cooling system – rapidly cools pellets to ambient temperature
- Storage silo – collects finished granules for packaging
Superior Material Properties & Product Performance
Hard PVC pellets produced by our line offer exceptional characteristics that make them the preferred feedstock for downstream processing:- Excellent flowability – uniform size and shape ensure consistent feeding to extruders and injection moulding machines
- High bulk density – reduces storage and transportation costs
- Consistent quality – precisely controlled formulations for repeatable end‑product properties
- Broad application suitability – ideal for pipe, profile, window frame, and injection‑moulded components
Versatile Material Capability
Our line is engineered to process a wide range of PVC formulations:- Rigid PVC (hard PVC) – standard and custom formulations for pipe and profile applications
- CPVC – chlorinated PVC for high‑temperature applications
- WPC compounds – wood‑plastic composite materials
- Recycled PVC – reclaim and waste PVC granulation
- Soft PVC – plasticised PVC compounds with appropriate screw design
Fully Automated Production Control
Integrated with advanced PLC control systems (Siemens, Omron, or Schneider) and intuitive HMI interfaces, the line offers full automation of extrusion parameters including melt temperature, screw speed, and cutting rate . Electrical components feature advanced frequency conversion technology for energy efficiency and precise control . Real‑time data acquisition, recipe management, and fault diagnostics ensure consistent quality and minimise production downtime.Main Line Components
