Laboratory Hydraulic Balanced Electric Two Roll Mill for Battery Electrode Rolling

Product Overview

This laboratory hydraulic balanced electric two roll mill is engineered for high-precision rolling of positive and negative battery electrode sheets. A servo hydraulic proportional valve system applies controlled rolling pressure, while the balanced rolling mechanism maintains stable compression across the working width. The result is improved transverse and longitudinal uniformity, consistent thickness control, and a high-quality electrode surface after rolling.

The equipment is suited to battery R&D laboratories, pilot-scale electrode processing, and advanced materials research. It supports demanding applications where rolling force and roll-gap consistency directly influence electrode density, thickness, surface finish, and downstream cell performance. Its compact laboratory format also makes it practical for universities, technical institutes, and industrial process-development teams.

A rigid integrated gantry frame, CNC precision machining, hardened chromium-plated rolls, and stable hydraulic pressure control provide a dependable foundation for repeatable operation. The system combines PLC and HMI control with force acquisition and storage, allowing users to monitor rolling-force curves and establish a more controlled process record under demanding laboratory conditions.

Key Features

• Servo Hydraulic Pressure Control: An imported servo hydraulic proportional valve system controls rolling pressure precisely, supporting applications that require consistent force and repeatable processing results.

• Hydraulic Balanced Rolling Mechanism: The patented balancing structure maintains stable pressure during operation and improves both transverse and longitudinal rolling uniformity across the workpiece.

• Rigid CNC-Machined Gantry Frame: The integrated gantry construction provides high structural stability. CNC precision machining supports accurate alignment of the roll system and reduces variation during repeated processing cycles.

• Wear-Resistant Precision Rolls: The rolls are manufactured from heat-treated 9Cr3Mo cold-rolling material and receive deep-cold treatment and hard chromium plating. The high internal and surface hardness improves wear resistance and service durability.

• Fine Roll-Gap Adjustment: A wedge-type roll-gap adjustment mechanism allows the working gap to be set from 0 to 3 mm. A digital dial indicator provides direct visual confirmation of the adjustment position.

• High Rolling Precision: The unit provides rolling precision of ±2 μm, with roll surface hardness of HRC65 to HRC70 and a hardened layer at least 15 mm thick. Roll runout is better than ±2 μm.

• PLC and HMI Operation: Programmable control and touchscreen operation make it convenient to set and manage operating parameters. The interface supports clear process adjustment for laboratory operators and technical development teams.

• Rolling-Force Data Management: The system can collect and store rolling-force data and display the force curve. This supports process monitoring, comparison between batches, and more disciplined experimental documentation.

• Practical Laboratory Configuration: Integrated lighting improves visibility of the rolling area, while universal casters simplify equipment movement within the laboratory. Protective panels and chromium-plated surfaces support cleaner, more maintainable operation.

• Continuous Processing Option: An optional unwind and rewind assembly can be configured for continuous rolling of coil-fed material, extending the system from individual sheet work to more efficient pilot-scale processing.

Applications

Technical Specifications

The pressure system is designed around controlled hydraulic loading rather than a manually applied force, allowing the operator to establish a stable rolling condition for each experiment. This is particularly important for battery electrode work, where small differences in compression can affect sheet thickness, porosity, density, and subsequent assembly behavior. The pressure measurement system and force-data storage function provide additional visibility into how the process behaves during a rolling cycle.

The roll assembly is sized for a maximum substrate width of 300 mm, with a 330 mm roll face width that provides practical working coverage for laboratory and pilot-scale electrode development. The 0-3 mm adjustable gap accommodates different sheet conditions and process targets. Within the specified operating range, rolling speed can be adjusted from 0.3 to 4 m/min to support controlled trials, material comparisons, and scale-up studies.

The roll construction is intended for repeated use in a research or process-development environment. The 9Cr3Mo roll material, heat treatment, deep-cold treatment, hard chromium plating, and specified surface hardness work together to support dimensional stability and wear resistance. A hard chromium layer of at least 0.15 mm also improves corrosion resistance and simplifies routine maintenance of the roll surface.

The integrated frame gives the equipment a stable structural platform while keeping the complete system within a laboratory-oriented footprint of 1400 mm by 500 mm by 1300 mm. Universal casters allow the equipment to be repositioned when laboratory layouts or process arrangements change. Integrated lighting assists operators in observing the roll area during setup and operation, and protective panels provide a more controlled working configuration.

PLC and HMI controls organize parameter setting and operation through a dedicated touchscreen interface. This arrangement supports consistent setup between operators and reduces dependence on informal manual adjustment. For laboratories comparing material formulations or rolling conditions, the ability to acquire and store rolling-force data adds useful traceability to the development workflow.

The electrical configuration uses single-phase 220 VAC±10% power at 50 Hz, with a total power requirement of 2 KW. The recommended operating environment is 25±3°C with humidity from 30 to 90 RH. Installation should be carried out in an area without vibration or electromagnetic interference so that the precision roll-gap and pressure-control functions can perform within their specified conditions.
