Zhitian All-Metal Ceramic Twin-Screw Extruder Barrel Liner: Empowering Efficient Production of Wet/Dry Electrodes and Solid-State Batteries


The Zhitian All-Metal Ceramic Twin-Screw Extruder Barrel Liner, engineered with nickel-based/cobalt-based cermet technology, is specifically designed for wet-process electrodes, dry-process electrodes, and solid-state battery production. It delivers ultra-wear resistance, corrosion resistance, and impact resistance, enabling continuous production, quality consistency, and reduced lifecycle maintenance costs.


Dedicated Twin-Screw Barrel for Lithium Battery Slurry Mixing

Industry Pain Points: Limitations of Traditional Extruders

In battery electrode manufacturing, traditional extruders face critical challenges:

  • Frequent Maintenance: Rapid wear of barrel components leads to unplanned downtime, disrupting production continuity.

  • Quality Instability: Material corrosion or metal contamination compromises product consistency.

The Zhitian All-Metal Ceramic Barrel Liner breaks through these barriers with innovative materials and precision engineering, providing reliable, high-performance solutions for battery manufacturing.


Technical Advantages: Breakthroughs in Cermet Liner Technology

The Zhitian Barrel Liner leverages nickel-cobalt composite cermet materials and advanced manufacturing processes to achieve:

  • Superior Wear Resistance: Dramatically extends service life and reduces maintenance frequency.

  • Exceptional Corrosion Resistance: Withstands harsh chemical environments (acids, alkalis, and organic solvents).

  • Zero Metal Contamination: Ensures electrode material purity and long-term battery safety.

Application Scenarios

  • Wet-Process Electrodes: Ideal for aqueous/organic solvent slurries in continuous extrusion.

  • Dry-Process Electrodes & Solid-State Batteries: Enhances powder mixing uniformity and high-pressure forming stability.
