MSK-HRP-22 Vertical Hot Rolling Press with Independent Dual-Roller Temperature and Speed Control
The MSK-HRP-22 is engineered for laboratory-scale hot rolling tasks, particularly suited for processing flexible films and dry electrode sheets used in lithium-ion and solid-air battery research. Its vertical roller arrangement facilitates gravity feeding of materials, enhancing the rolling process by applying shear forces that improve film uniformity and density.
This compact rolling press integrates two 100 mm diameter steel rollers with a width of 100 mm, each independently controlled for temperature and speed. The system includes a separate touchscreen control unit that allows precise adjustment of rolling parameters and real-time monitoring of rolling force, speed, and temperature. The unit can be installed inside an inert atmosphere glovebox with optional KF40 ports for external control access.
Key Features
- Dual independent temperature control for front and rear rollers, programmable with 30 segments from room temperature to 200°C.
- Asynchronous speed control of two rollers via high-torque 24VDC brushless motors, adjustable from 0.5 to 12.5 RPM.
- Digital pressure display with built-in load cell, measuring up to 2 tons of force in real time.
- Rollers made of CrMoV steel with hardness HRC 52, suitable for materials up to 40 HRC hardness.
- Manual roller gap adjustment with 0.001 mm resolution for precise thickness control up to 1.8 mm.
- Separate control unit with touchscreen interface and optional RS-485 communication for PC software integration.
- Optional configuration for horizontal setup and multi-layer rolling available upon request.

Typical Applications
The MSK-HRP-22 is ideal for preparing flexible films and dry electrode sheets for lithium-ion and solid-air batteries. Its vertical rolling mode supports gravity feeding of powder or film materials, enabling uniform calendering and shear force application. It is also suitable for dry cathode and anode fabrication, including graphite anodes and NCM811 cathodes, with optional horizontal setup for specific electrode shaping.
Configuration & Operating Notes
The rolling press can be installed inside an argon glovebox using optional KF40 feedthrough ports to keep the control unit external. Users should avoid rolling materials harder than 40 HRC to prevent roller damage. Multi-step calendaring with thickness decrements not exceeding 0.02 mm per pass is recommended for optimal film quality. Roller surfaces must be cleaned before and after use and lubricated during idle periods to prevent corrosion. Optional accessories include multi-layer rolling configurations and material feeders.
