Description

ATOMFAIR® ATOMFAIR-ETR5029 ELECTRIC TWIN ROLL MILL

RESEARCH GRADE MATERIAL

Product Overview
The ATOMFAIR® Atomfair-ETR5029 Twin Roll Mill is an advanced, automated motorized calendar platform engineered for high-accuracy film compaction and strip material processing applications. Operating as a flexible 200mm Calendering System, this instrument enables micro-controlled thickness reductions across electrode matrices, precious metal ribbons, and complex non-ferrous foils. The upright architectural profile incorporates an active mechanical assembly governed by an inclined block stability matrix to lock the operational roller clearance flawlessly under counter-force loading. Driven by heavy-duty synchronous gears, the electric drivetrain provides continuous forward and reverse operation, ensuring optimal material handling for world-class technical laboratories and clean energy R&D initiatives.

Key Features & Advantages
  • Micro-Adjustable Wedge Calibration: Outfitted with an advanced mechanical inclined block gap configuration that enforces dependable self-locking performance, removing roller gap displacement under active rolling counter-pressures.
  • Vertical Orientation Feeding Path: Upright structural layout optimizes the feeding and extraction path for continuous strip foils, eliminating any risk of material wrinkling or uncoordinated sheet tracking.
  • Hardened Chromium Electroplated Surface: Roller cores are processed to exceed ≥ HRC 62 via specialized surface treatment, introducing superb chemical resistance against oxidation and fine battery slurry particulates.
  • Bi-Directional Automated Drivetrain: High-efficiency motorized rolling loop supports forward and reverse rotation scripts seamlessly, enabling instantaneous material withdrawal for process optimization.

APPLICATION SCOPE: Crafted specifically for thinning wider battery electrode slurry coatings, densifying solid-state electrolyte sheets, processing metallic ribbon substrates, and calendering composite polymeric membranes.
PACKAGING: Encased in an export-grade 485 × 245 × 355 mm wooden shipping crate lined with custom-cut structural isolation pads to prevent misalignment of the vertical precision rolls during transit.
IMPORTANT NOTICE: Never feed hard, non-deformable materials or scrap pieces exceeding the maximum 2 mm clearance envelope. Ensure single-phase power connections comply precisely with the stated AC 220V frequency configuration to maintain operational safety.

Store the equipment in a dry, dust-free environment to prevent electrical component degradation. Operate only with proper grounding and ensure the area is free of flammable vapors to mitigate electrical hazard.

  • Electrical Safety: Disconnect power before performing any maintenance or cleaning to avoid electric shock.
  • Mechanical Pinch Hazard: Keep hands and loose clothing away from rotating rolls during operation to prevent entanglement.
  • Roll Surface Protection: Avoid feeding materials with sharp edges or abrasive particles that could scratch the hard chrome plating.
  • Environmental Moisture: Do not operate the mill in condensation-prone environments to reduce risk of electrical short circuit.
  • Grounding Requirement: Verify that the AC220V outlet is properly grounded before plugging in the equipment.

This procedure covers initialization, roll gap adjustment, feeding, and shutdown of the twin roll mill. Follow these steps to ensure safe and precise rolling of strip materials.

Required Equipment:

  1. Power On and Safety Check
    Inspect the emergency stop button and ensure the power cord is connected to a grounded outlet before switching on the main power.
  2. Adjust Roll Gap
    Turn the inclined block adjustment mechanism to set the desired rolling thickness between 0 and 2 mm, verifying with a feeler gauge.
  3. Set Feeding Speed
    Rotate the speed control dial to select a feeding rate between 0 and 50 mm/s appropriate for the material.
  4. Load Strip Material
    Align the leading edge of the strip material with the roll nip and feed it straight into the vertical rolls.
  5. Engage Rolling
    Press the forward button to start automated rolling and monitor the material passage for uniform thickness.
  6. Reverse Direction if Needed
    Press the reverse button to back the strip out for re‑adjustment or to clear a jam, keeping hands clear of the nip.
  7. Shutdown and Clean
    Turn off the main power after rolling is complete and wipe the roller surfaces with a lint‑free cloth to remove residue.

How does the ±2μm roll cylindricity affect thickness uniformity when rolling materials at different thickness settings within the 0-2mm range?

The ±2μm cylindricity ensures high rolling precision across the entire 0–2mm adjustable thickness range, minimizing thickness variation along the strip. This precision is supported by the hard chrome-plated rolls with a surface hardness above HRC62 and the inclined block adjustment mechanism, which provides excellent self-locking and high adjustment accuracy.

Can the Atomfair-ETR5029 process strip materials wider than 200 mm?

No, the pressing width is fixed at 0–200 mm, so materials exceeding this width cannot be processed. The vertical design and gear drive are optimized for strip materials within this width range, and the adjustable feeding speed of 0–50 mm/s accommodates various material feed rates without exceeding the width constraint.

What electrical and installation infrastructure is required to operate this twin roll mill?

The mill requires a standard AC220V/50Hz single-phase power supply with a 120W power consumption. Its compact dimensions of L485mm × W245mm × H355mm and 65 kg weight allow benchtop placement, but the supporting surface must be capable of bearing the weight, and the vertical design requires unobstructed access from above for feeding strip material.

The Atomfair-ETR5029 Electric Twin Roll Mill delivers high-precision rolling with ±2μm cylindricity and hard chrome rolls (HRC62), ideal for thin-strip processing in battery electrode and advanced materials labs. Its 2mm thickness limit and 120W motor restrict throughput for thicker or high-density materials, making it best suited for low-force, precision film applications.

Positive

  • High rolling precision with ±2μm cylindricity: Roll cylindricity maintained at ±2μm ensures uniform thickness control across strip materials, critical for consistent mechanical and electrical properties in battery electrodes or thin-film processing.
  • Hard chrome rolls with HRC62 hardness: Surface hardness exceeding HRC62 combined with hard chrome plating provides exceptional wear resistance and corrosion protection, extending roll service life under continuous operation.

Trade-offs

  • Thin-strip thickness limit (max 2mm): The rolling thickness range of 0–2 mm restricts this mill to thin films, foils, and electrode coating substrates; thicker or bulk material cannot be processed.
  • Low motor power (120W) constraint: With a 120W motor, the mill is suited for low-force applications; processing of high-strength, dense, or wide materials at high feed speeds may stall or overheat the drive.
