MSK-BPC-DF200 Three-Roller Continuous Hot Rolling Press with Asynchronous Speed Control for Dry Electrode and Solid-State Electrolyte Sheets
The MSK-BPC-DF200 is engineered to address the challenges of fabricating dry electrodes and solid-state electrolyte sheets used in lithium-ion battery research and development. It enables precise rolling of dry electrode films up to 200 mm in width, ensuring uniform thickness and density critical for battery performance. This model supports continuous operation with independent control of three roller pairs, allowing asynchronous speed and pressure adjustments tailored to specific material properties and process requirements.
Each roller can be heated up to 150°C independently, facilitating hot rolling processes that improve film compaction and adhesion. The rolling pressure can reach up to 10 tons with fine resolution, ensuring consistent force application across the rollers. The system includes a PVC winding core for collecting rolled films, with manual tension and speed adjustments to optimize winding quality. An optional automatic powder feeder enhances productivity by enabling automated roll-to-roll dry film preparation.
Key Features
- Three pairs of DC53 steel rollers (Ø150 mm x 220 mm) with hardness HRC 60-62 for durability and precision.
- Independent asynchronous speed control ranging from 0.05 to 1 m/min for each roller.
- Maximum rolling pressure of 10 tons with applied force resolution better than ±0.5% above 1 ton.
- Adjustable roller gap from 0 to 1.2 mm with ±0.001 mm accuracy.
- Roller temperature control up to 150°C for enhanced material processing.
- Effective rolling width of 200 mm suitable for dry electrode film fabrication.
- Optional automatic powder feeder for continuous roll-to-roll dry film production (requires software upgrade if ordered before August 1, 2026).

Typical Applications
The MSK-BPC-DF200 is ideal for producing dry electrode films and solid-state electrolyte sheets used in lithium-ion battery development. It supports the rolling of spherical powder-based cathode electrodes and facilitates lamination processes when combined with compatible roll-to-roll laminators. The equipment is suited for research labs and pilot production environments focusing on advanced battery materials.
Configuration & Operating Notes
An automatic powder feeder is available as an optional accessory to enable automated roll-to-roll dry film preparation. For units ordered before August 1, 2026, a software upgrade is necessary to operate this feeder. The dry electrode film length is limited to approximately 20 meters in the current configuration; longer films require winding system upgrades. Optimal operation is recommended in a controlled environment at 25 ± 3°C without vibration or electromagnetic interference.
