Dry Battery Electrode Development
Accelerate Dry Electrode Innovation with Full-Process Control
The GK 300 L 6R replicates multi-stage industrial calendering for dry battery electrode R&D. Its precision-controlled roller system and modular process configuration allow researchers to simulate full production workflows with exceptional flexibility and technical accuracy.
Dual Operating Modes for Film Formation & Lamination
The 6-roll calender supports two distinct operating modes:
- Double-sided lamination (+film): Simultaneously creates films on both sides and laminates them onto a substrate — ideal for symmetric layer formation.
- Single-sided lamination (+film): A dry film is generated and laminated on one side only, using a single hopper and modified roller routing — optimal for asymmetric designs and process-specific tuning.
Realistic Multi-Nip Simulation for Dry Electrode Research
Our modular calender system features a three-gap configuration that enables complete process validation across all critical stages of film development.
In the first gap, dry film formation is achieved under precisely controlled conditions. The second gap allows for compaction or densification, ensuring structural stability and optimized mechanical properties. In the third gap, single- or double-sided lamination or film finalization is carried out to achieve the desired surface characteristics.
With independent gap control at each stage, this configuration enables full-process validation of pressure, film thickness, and mechanical integrity.
Process-Ready Platform for Advanced R&D
With integrated unwinder/rewinder systems, in-line IR preheating, edge trimming, gap measurement, and a dedicated control panel, the GK 300 L 6R enables accurate testing of binder-free formulations, dry powders, and sensitive film laminations. The modular system can be reconfigured to match your evolving testing protocols.

Optional remote service interface enables online support, diagnostics, and updates by our engineers via secure GSM or LAN connection.
High-Precision Hydraulic Gap Control (standard)
Hydraulically regulated gap control system ensures accurate pressure distribution and micrometer-level gap control across all three nips. Live digital feedback supports continuous process optimization.
Edge Cutting and Doctor Blades (standard)
Manual crush cutters enable precise edge trimming, while integrated doctor blade systems ensure clean, residue-free roller surfaces during processing.
Roller Temperature Management
Each roller includes integrated electrical cartridges for temperature regulation to 150 °C, with optional upgrade to 200 °C for special materials. Control is managed through a mobile panel with ±1 °C accuracy.
