This twin roll mill is designed for precise rolling of battery electrodes and soft metal foils. Maintaining roll surface integrity and alignment is critical to achieving consistent thickness and avoiding material defects.

• Material Hardness Limit: Do not roll materials with hardness exceeding HRC62 to prevent damaging the chrome-plated roll surface.
• Operational Stability: Operate the mill on a rigid, vibration-free surface to preserve roll cylindricity and ensure uniform pressure distribution.
• Roll Surface Cleanliness: Keep roll surfaces free of debris and residual material to avoid scratching the finish and compromising rolling accuracy.

This manual twin roll mill uses vertical roll placement and an inclined block for precise gap adjustment. Follow the steps below to safely and effectively roll battery electrode plates or similar thin materials.

1. Inspect Rolls
   Inspect the roll surfaces for any debris, residue, or damage before starting each rolling session.
2. Adjust Roll Gap
   Adjust the rolling gap using the inclined block to the desired thickness within the 0–2 mm range.
3. Feed Material
   Insert the material strip vertically between the rolls at the feed side, ensuring alignment with the roll width.
4. Activate Rolling
   Turn the handwheel clockwise to engage the gear drive and draw the material through the roll nip.
5. Verify Thickness
   Verify the rolled thickness with a micrometer and repeat the process if further reduction is needed.
6. Clean Rolls
   Clean the roll surfaces with a soft, lint-free cloth after each use to maintain surface finish and precision.

The Atomfair-MTR7083 Manual Twin Roll Mill delivers high-hardness chrome rolls (HRC62) and ≤±2μm cylindricity for precise lab-scale densification and thinning of lithium battery plates, though manual operation demands skilled consistency and the 100mm rolling width restricts larger electrode strips.

Positive

• High-hardness chrome rolls with rust resistance: Roll surface hardness exceeds HRC62 with hard chrome plating, providing durability and corrosion resistance for repeated use with battery materials.
• High rolling accuracy for uniform thickness: Roll cylindricity ≤±2μm ensures consistent gap and thickness control critical for electrode densification and thinning in lithium battery processing.

Trade-offs

• Manual operation requires skilled consistency: Manual feed and gap adjustment rely on operator technique, introducing variability in rolling force and thickness repeatability compared to motorized systems.
• Limited rolling width for larger samples: Maximum rolling width of 100mm constrains the size of electrode strips or foils that can be processed, requiring narrow sample preparation.
