Integrated Dual Servo Heated Horizontal Two Roll Mill for Battery Electrode Calendering

Product Overview

This integrated dual servo heated horizontal two roll mill is designed for electrically driven rolling of battery materials and other nonferrous materials at controlled temperatures. Its adjustable roll gap, digitally displayed operating values, and independent upper and lower heating controls help researchers reduce material thickness while increasing density with direct, repeatable process adjustment.

The equipment is especially suitable for lithium battery electrode processing, including the reduction and densification of electrode sheets. It also supports laboratory work involving clean-energy materials, powder-based materials, and related advanced-materials research where controlled rolling, flexible speed adjustment, and optional heating are required.

A rigid compact construction combines high-hardness rolls, hard chromium-plated surfaces, precision cylindrical geometry, and servo-driven control. The result is a practical laboratory unit for demanding development work where stable material handling, clear operating feedback, and consistent processing conditions are essential.

Key Features

• Dual Servo Drive Control: Independent upper and lower servo control supports accurate speed adjustment and asynchronous rotation. Operators can set the two roll speeds separately to match material behavior and process requirements.

• Integrated Roll Heating: Internal roll heating provides direct thermal conditioning during rolling. The upper and lower rolls are controlled independently, allowing different temperature settings when the process requires asymmetric thermal control.

• Wide Temperature Flexibility: The unit can operate with heating enabled or disabled. Temperature settings range from room temperature to 130°C, with digital display and 0.1°C temperature resolution.

• Precise Roll Gap Adjustment: A wedge-block adjustment mechanism provides self-locking performance and accurate control of the pressing gap. The electronically displayed gap value makes thickness adjustment easier to observe and repeat.

• High-Quality Roll Surfaces: The rolls have HRC62 hardness and hard chromium-plated surfaces, supporting durable contact with processed materials and stable rolling performance during repeated laboratory use.

• High Geometric Precision: Roll cylindricity is maintained within ≤±2 μm, helping produce more uniform sheet processing across the available working width.

• Clear Digital Monitoring: Digital displays provide direct observation of sheet thickness and rolling speed. Operators can monitor and adjust critical process variables without relying on visual estimation.

• Reversible Electric Operation: Motorized rolling supports forward and reverse operation, improving handling flexibility during material feeding, adjustment, and process development.

• PLC-Based Automation: PLC screen control supports automated operation and precise speed adjustment. The control interface consolidates key operating functions in a compact laboratory format.

• Compact Material Feeding: The included hopper facilitates the introduction of powder-form feedstock. The compact footprint and straightforward operation make the equipment practical for flexible laboratory workflows.

Applications

Technical Specifications

The dual servo arrangement is central to the operating flexibility of this equipment. Upper and lower roll speeds can be adjusted independently, allowing asynchronous rotation when the material or experimental method benefits from differential surface speed. This feature gives researchers greater control over rolling behavior than a mechanically linked drive system.

Thermal control is similarly adjustable. Each roll includes internal heating and an independent temperature controller, with digital values displayed for direct monitoring. The available room-temperature-to-130°C range covers common laboratory trials for thermally assisted electrode and material rolling. A selectable unheated mode also allows users to perform ambient-temperature experiments without changing the equipment configuration.

Mechanical adjustment is designed for repeatable laboratory work. The wedge-block mechanism provides self-locking gap adjustment, while the digital thickness display helps the operator observe and fine-tune sheet thickness. With a selectable rolling thickness from 0 to 3 mm and a sheet width from 0 to 200 mm, the system accommodates a broad range of small-scale material-processing studies.

The roll geometry and surface construction support consistent contact with the processed material. A roll diameter of Φ96 mm, cylindricity of ≤±2 μm, HRC62 hardness, and hard chromium-plated surfaces provide a precise and durable working interface. The 0.8 surface finish is specified for the rolls, giving buyers a clear basis for evaluating the equipment against their material and process requirements.

The PLC control screen organizes automated operation and speed adjustment in a compact format. Forward and reverse electric rolling improves operational flexibility, while the hopper makes it easier to introduce powder-form feedstock. These features help reduce setup complexity for laboratory teams moving between different materials, thickness targets, and processing conditions.

Why Choose This Product

• Precision-Oriented Construction: Roll cylindricity of ≤±2 μm, HRC62 roll hardness, and hard chromium-plated surfaces provide a strong foundation for consistent laboratory rolling.

• Flexible Process Control: Independent servo speeds, asynchronous rotation, reversible operation, adjustable gap, and optional heating allow researchers to configure the process around specific material behavior.

• Controlled Thermal Performance: Independent upper and lower roll heating, 0.1°C resolution, and ±2°C control accuracy support clearly defined thermal experiments.

• Efficient Laboratory Integration: PLC control, digital thickness and speed displays, powder feeding through the hopper, and compact dimensions simplify daily operation in research environments.

• Built for Repeatable Development Work: The combination of durable roll construction, electric automation, and direct process visibility supports reliable trials across battery and advanced-materials applications.
