When sourcing twin screw extruder barrels for lithium battery slurry mixing, engineers and buyers face three main challenges:
material compatibility, service life, and replacement accuracy.
ZHITIAN provides a comprehensive OEM and custom solution, designed to reduce maintenance frequency while maintaining slurry purity and mixing consistency.

For continuous lithium battery slurry systems, barrel materials must resist chemical corrosion from NMP solvents and abrasion from conductive agents like carbon black and CNTs.
ZHITIAN offers two proven liner materials:

Both liners are precision fitted into a 304 stainless steel barrel shell, ensuring structural stability and long-term reliability under thermal cycling.

ZHITIAN specializes in OEM-equivalent barrels for major twin screw mixer brands used in lithium slurry production.
Each barrel is manufactured according to original design parameters or reverse-engineered drawings, ensuring:

Perfect alignment with existing screw and gearbox systems

No need for on-site adjustment

Immediate installation and production restart

For global buyers, this means shorter lead time, lower replacement cost, and stable process continuity.

The inner cooling channels of ZHITIAN barrels are optimized for thermal uniformity during high-viscosity slurry processing.
This ensures:

Even temperature distribution

Consistent slurry viscosity

Reduced binder degradation (PVDF, CMC, SBR systems)

The smooth, precision-machined bore enhances material flow and minimizes dead zones — a critical factor for slurry uniformity in cathode/anode material manufacturing.

Every ZHITIAN barrel undergoes:

Dimensional inspection within ±0.02 mm

Liner bonding integrity testing

Hydraulic pressure and cooling channel leakage test

ZHITIAN supplies both OEM replacement parts and custom-designed barrels for battery material manufacturers worldwide, with proven performance in:

China, South Korea, Germany, and Italy

Lithium material pilot lines and full-scale production plants

OEM replacement compatibility
Lower total cost of ownership
Extended wear and corrosion life
Proven in battery material mixing environments
Rapid customization and delivery

Q1: Can ZHITIAN manufacture barrels based on samples or worn parts?
Yes. We provide reverse engineering and 3D scanning services to replicate and optimize OEM designs.

Q2: Which liner should I choose for my lithium slurry system?

Use ZT615 Ni-Cr alloy if your process involves strong solvents or high-purity requirements.

Use WR13 High-Cr alloy if you need a cost-effective solution with good wear resistance.

Q3: Is the barrel compatible with European or Japanese twin screw mixers?
Yes. ZHITIAN produces barrels for various OEM models, including custom configurations for imported equipment.

Q4: Can you supply a complete barrel + screw + gearbox package?
Absolutely. ZHITIAN provides integrated twin screw extruder component solutions, including screws, barrels, and gearboxes.
