    Performance & Features by Line Configuration

    CJWS75 Twin-Screw Extruder

    ⚙️ Main Extruder Model

    CJWS75

    ⚡ Motor Power

    450 kW (AC frequency motor), maximum screw speed up to 900 RPM, energy-saving and high efficiency.

    📦 Output Capacity

    1–2 T/h

    ⚖️ Loss-in-Weight Feeding System

    Automatic high-precision metering and feeding for multiple materials, ensuring accurate formulation control.

    🎯 High-Precision Metering

    Automatic material weighing to ensure consistent and stable product quality.

    🛡️ Durable Barrel

    The barrel is equipped with integral tungsten carbide alloy liners, extending service life and reducing maintenance costs.

    🔩 High-Performance Screw Elements

    Screw elements made of powder metallurgy (PM), featuring high wear resistance and mechanical strength to ensure long-term stable operation.

    🔬 Glass Fiber Reinforced Side Feeder

    The side feeding design allows glass fibers to be introduced into the main material flow in a controlled and sectional manner, preventing fiber agglomeration and improving dispersion uniformity in the matrix.

    Low-shear feeding helps preserve fiber length (especially long fibers of 6–25 mm), reduces fiber damage, and enhances final product density through efficient high-vacuum degassing.

    The buffer hopper is equipped with an agitator to prevent material bridging and improve feeding efficiency.

    🏭 Automated Production System

    Equipped with small bag and big bag feeding stations, quick-opening strand die head, cooling water tank, air knife, gantry pelletizer, lifting conveyor, finished product homogenization silo, and automatic bagging system to improve overall production efficiency.
