Heated Roll to Roll Roller Press Battery Electrode Two Roll Mill Laboratory Two Roll Mill

Product Overview

This heated laboratory roll to roll roller press is an electrically driven two roll processing system for controlled reduction and densification of battery electrode materials. It combines adjustable rolling thickness, independently heated upper and lower rolls, digital speed indication, and continuous web handling in one compact laboratory platform. The equipment is designed for users who need repeatable calendering results while retaining direct control over the processing gap, temperature, and feed rate.

The system is particularly suitable for lithium battery electrode sheets used in clean energy research, as well as small quantities of gold, silver, copper, aluminum, and other nonferrous materials. It supports electrode thinning and density increase under controlled thermal conditions, making it useful for battery R&D, advanced materials laboratories, powder processing studies, and university research environments.

Hardened precision rolls, controlled heating, and adjustable operating parameters support stable processing under demanding laboratory schedules. Digital displays make speed and temperature easy to observe and adjust, while continuous operation enables consistent treatment of longer electrode strips. The compact construction and defined roll geometry provide a practical balance between precision, durability, and accessible operation.

Key Features

• Independent Roll Heating: The upper and lower rolls can be heated independently from room temperature to 130°C. Separate adjustment supports more controlled thermal processing when electrode behavior or material response requires a defined temperature profile.

• Precise Temperature Regulation: Digital temperature indication, a temperature resolution of 0.1°C, and control accuracy of ±0.5°C give researchers close oversight of heat-assisted rolling conditions. This supports repeatable electrode preparation and controlled material densification.

• Adjustable Rolling Gap: The rolling gap is adjustable from 0 to 2 mm, allowing users to tune final sheet thickness for different electrode formulations, material types, and experimental objectives. The adjustable setting also supports systematic thickness studies.

• Hardened Precision Rolls: The rolls have a hardness of HRC62 and a surface finish of Ra0.4 or better. These characteristics support wear resistance, consistent contact with the workpiece, and a stable working surface during repeated laboratory processing.

• Controlled Roll Geometry: Roll cylindricity is maintained within ≤±2 µm. This precision helps provide uniform pressure distribution across the working zone and supports consistent electrode thickness from one test to the next.

• Digital Feed Speed Control: The electric drive provides a feed speed of 0 to 40 mm/s with digital display and precise observation and adjustment. Users can establish repeatable rolling conditions and evaluate the influence of processing speed on electrode quality.

• Continuous Roll to Roll Operation: Unwinding and rewinding components support continuous running for strip and web materials. This configuration is suitable for processing electrode sheets beyond the limits of short, manually fed samples.

• Compact Laboratory Footprint: The rolling unit measures L670 mm × W220 mm × H330 mm. Its narrow footprint is suited to laboratories that require controlled calendering capability without allocating space for a full production-scale line.

• Controlled Web Tension: The roll to roll section provides maximum tension control of 20 N and accepts 3 inch roll cores. This helps maintain orderly material transport through the process and reduces variation caused by uncontrolled strip handling.

Technical Specifications

Rolling Unit

Unwind and Rewind Components

The rolling unit uses 100 mm diameter vertically positioned rolls with a hardness of HRC62, a surface finish of Ra0.4 or better, and cylindricity of ≤±2 µm. Together, these specifications define the working geometry and surface condition used for laboratory calendering. The 0 to 2 mm adjustable gap gives operators a practical range for controlled thickness reduction and densification.

Thermal operation is provided through independently heated upper and lower rolls. The selectable range extends from room temperature to 130°C, with digital temperature display, 0.1°C resolution, and ±0.5°C control accuracy. This arrangement allows researchers to compare unheated and heated rolling conditions, or to establish different upper and lower roll settings when the experiment requires independent thermal control.

Material transport is designed for continuous running. The guide roll width is 200 mm, the mechanical speed is a maximum of 1.5 m/min, and maximum tension control is 20 N. The unwind and rewind assemblies use 3 inch roll cores and support a maximum roll diameter of 200 mm. These values define the compatible web-handling configuration for continuous electrode and material-strip processing.

The electrically operated rolling unit uses AC220V/50Hz power and has a rated power of 1 kW. Its overall dimensions are L670 mm × W220 mm × H330 mm, with a listed weight of 70 kg. The feed speed is independently specified as 0 to 40 mm/s and is digitally displayed for accurate observation and adjustment during operation.

The unwind and rewind components require a single-phase 220 VAC ±10% power supply at 50 Hz/60 Hz, with 110 VAC available as a customizable option. Their listed power is 100 W. The unwind installation envelope is W300 mm × D250 mm × H280 mm, while the rewind installation envelope is W300 mm × D350 mm × H280 mm. The unwind component weighs approximately 15 kg, the rewind component approximately 20 kg, and the combined weight is 35 kg total.

Why Choose This Product

• Precision-Oriented Construction: HRC62 rolls, Ra0.4 or better surface finish, and ≤±2 µm cylindricity support stable contact conditions and consistent processing across repeated laboratory trials.

• Thermal and Mechanical Control in One System: Independent roll heating, ±0.5°C temperature control accuracy, adjustable 0 to 2 mm gap, and digitally displayed feed speed give buyers direct control over the primary variables affecting electrode calendering.

• Designed for Continuous Research Workflows: The unwind and rewind assemblies, 3 inch cores, maximum 200 mm roll diameter, and 20 N tension control support orderly roll to roll processing instead of limiting experiments to short manually handled samples.

• Efficient Laboratory Integration: A compact rolling unit, electric operation, defined installation dimensions, and customizable 110 VAC supply option make the equipment practical for laboratories with constrained space or region-specific electrical requirements.

• Suitable for High-Value Materials: Controlled thickness reduction for battery electrodes, precious metals, copper, aluminum, and other nonferrous materials helps laboratories protect sample value while generating repeatable process data.
