Product Description
The ZHITIAN Twin Screw Extruder Barrel is specifically engineered for lithium battery slurry homogenization applications.
It is designed to deliver stable mixing performance, superior corrosion resistance, and long service life under continuous operation conditions of cathode and anode slurry processing.
1. Structural Design for High-Viscosity Slurry Mixing
This barrel adopts a dual-layer composite structure:
- Outer Shell: 304 stainless steel, ensuring excellent strength and oxidation resistance.
- Inner Liner: Optional ZT615 nickel-chromium alloy or WR13 high-chromium iron-based alloy, providing an optimal balance between wear resistance and chemical stability.
This configuration effectively resists both the abrasive conductive materials and corrosive binder-solvent systems used in lithium battery slurry.
2. ZHITIAN Alloy Technology — Precision and Durability
ZT615, developed by ZHITIAN, is a nickel-chromium alloy with enhanced metallurgical bonding strength and uniform microstructure, ideal for corrosive polymer and chemical environments.
Alternatively, the WR13 high-chromium liner provides a cost-effective solution with strong resistance to mechanical wear and mild corrosion.
Both alloys undergo controlled heat treatment and precision CNC machining, ensuring long-term dimensional stability and smooth internal surfaces for efficient material flow.
3. Thermal Management & Process Stability
The barrel’s internal cooling channels are optimized for pulsed temperature control, maintaining consistent mixing conditions and preventing localized overheating.
This results in:
- Stable slurry temperature
- Reduced binder degradation
- Enhanced slurry dispersion uniformity
Such design guarantees reliable operation in twin screw continuous slurry mixers used in lithium-ion battery electrode production lines.
4. Typical Applications
- Cathode Material Mixing: LFP, NCM, NCA
- Anode Material Mixing: Graphite, Silicon-based, Hard Carbon
- Binder Dispersion: PVDF, CMC/SBR Systems
- Additive Blending: Conductive Carbon Black, CNTs
ZHITIAN’s high-precision barrels are widely used by battery material manufacturers, extrusion system OEMs, and slurry process equipment integrators worldwide.
5. Key Advantages
- Optimized design for lithium slurry rheology
- Excellent chemical resistance against NMP and electrolyte residues
- Extended service life under abrasive-carbon environments
- OEM-compatible replacement for leading twin screw mixer brands
- Manufactured under ISO9001 quality management with 100% inspection
