Key Features & Advantages
  • Dual-Mode Thermal Management: Features a high-accuracy digital thermal regulator supporting active heating up to 200 °C or classical cold rolling modes to match different material properties.
  • Self-Locking Wedge Gap Controls: Engineered with a wedge-block calibration system that delivers reliable self-locking stability, preventing gap migration under severe material counter-pressures.
  • Hardened Chronium Roll Core: High-density roll surfaces are hardened to ≥ HRC 62, offering great resistance against wear, abrasion, and chemical corrosion from chemical powder coatings.
  • Synchronized Gear Meshing: Powered by an automated gear-driven double-roll system that provides balanced pressure distribution and a smooth feed profile, significantly reducing material deformation.

APPLICATION SCOPE: Crafted specifically for thinning battery electrode slurry coatings, refining polymer composite sheets, processing thin-film precious metals, and consolidating advanced solid-state electrolyte matrices.
PACKAGING: Encased inside an export-grade 500 × 220 × 320 mm protective crate lined with custom-cut structural isolation pads to prevent misalignment of the precision rolls during transit.
IMPORTANT NOTICE: Never feed materials that exceed the maximum 2 mm clearance envelope. Ensure the hard-chrome roll surfaces remain completely free of abrasive particulates prior to adjusting the wedge-block mechanism.

This device requires operation within specified electrical and thermal safety limits to prevent hazards and equipment damage. The mechanical pinch points demand careful handling and proper guarding.

  • Electrical Safety: Operate only with a grounded AC220V/50Hz power supply to mitigate electrical shock risk.
  • Thermal Management: Monitor the heating controller to ensure the roll temperature does not exceed the maximum design temperature.
  • Mechanical Hazard: Keep hands and loose clothing away from rotating rolls during operation and ensure safety guards are in place.

Follow these steps to safely thin lithium battery plates using the heated rolling mill. Always wear protective equipment and verify machine settings before operation.

  1. Adjust Rolling Thickness
    Set the wedge block to achieve the desired gap between the rolls.
  2. Set Rolling Temperature
    Configure the digital controller to the required temperature and wait for stabilization.
  3. Set Feeding Speed
    Adjust the feeding speed to the required rate using the speed controller.
  4. Start Roll Rotation
    Activate forward rotation to initiate the rolling process.
  5. Feed Material
    Introduce the battery plate into the roll nip uniformly to ensure consistent thinning.
  6. Monitor and Inspect
    Observe the output plate for uniform thickness and adjust parameters if necessary.
  7. Shutdown Procedure
    Stop heating and rotation, then allow the rolls to cool before cleaning.

How does the roll cylindricity of ≤±2μm affect thickness uniformity when calendering lithium battery electrodes on the Atomfair-RM-7259?

The roll cylindricity of ≤±2μm directly ensures high flatness and thickness consistency of rolled sheet and strip materials, which is critical for uniform electrode density in battery plates. This precision is further supported by the wedge block gap adjustment with self-locking, enabling fine control within the 0-2mm rolling thickness range.

What range of lithium battery plate thicknesses and widths can the Atomfair-RM-7259 handle in a single pass?

The mill accommodates rolling thickness from 0 to 2 mm and tableting width up to 100 mm, with adjustable feeding speed from 0 to 10 mm/s. This makes it suitable for processing typical lab-scale electrode strips used in coin cells and small pouch cells, balancing precision with throughput.

What are the electrical and spatial requirements for installing the Atomfair-RM-7259 heated rolling mill in a standard laboratory?

The mill requires a standard AC220V/50Hz power supply with 720W consumption and occupies a compact footprint of 500mm × 220mm × 320mm (L × W × H). Weighing 55 kg, it can be placed on a robust benchtop without specialized infrastructure, making it practical for limited-space lab deployments.

The Atomfair-RM-7259 is a compact heated rolling mill with HRC62 hard chrome rolls and dual heating/non-heating modes, designed for precision thinning of lithium battery plates and small-batch production, offering temperature control to 200°C and rolling accuracy of ≤±2μm cylindricity.

Positive

  • Precise Heated Rolling with Digital Control: Integrated temperature controller enables adjustable heating up to 200°C with digital display, ensuring accurate thermal conditions for consistent material densification.
  • High Roll Cylindricity for Uniform Thickness: Roll cylindricity ≤±2μm guarantees excellent flatness and consistency of rolled sheets, critical for precision applications like battery electrode processing.

Trade-offs

  • Maximum Temperature Limited to 200°C: The rolling temperature maxes out at 200°C, which may not suffice for materials requiring higher thermal activation or softening points.
  • Restricted Rolling Thickness Range: Adjustable thickness is limited to 0-2 mm, confining the mill to thin-film applications and excluding thicker material processing.
