Laboratory Electric Vertical Two Roll Mill 100mm 200mm 300mm Width

Product Overview

This laboratory electric vertical two roll mill is designed for controlled thinning and density enhancement of battery materials, lithium battery electrode sheets, and other clean energy materials. Its geared transmission drives two counter-rotating rolls for stable, repeatable rolling, while the adjustable roll gap allows users to set the required sheet thickness for different material conditions and research protocols. The vertical arrangement supports convenient feeding of sheet and strip materials into the rolling zone.

The equipment is suited to battery R&D laboratories, clean energy material development, powder processing studies, and academic materials research. It provides a compact and flexible solution for electrode densification, thickness reduction, and process parameter evaluation where laboratory floor space, adjustment accuracy, and operational convenience are important.

High roll hardness, hard-chrome surface treatment, fine roll cylindricity, and direct digital adjustment support dependable processing under demanding laboratory workloads. The compact structure is easy to operate and reposition, while the geared drive and protected transmission are built to deliver consistent performance over repeated development cycles.

Key Features

• High-Hardness Working Rolls: The rolls are hardened to HRC62 and finished with hard chrome plating. This treatment improves surface durability and provides rust resistance, helping preserve working quality during repeated laboratory use.

• High Roll Cylindricity: Roll cylindricity is controlled to ≤±2 µm, supporting uniform contact across the working width and reducing variation during electrode and sheet-material processing.

• Adjustable Rolling Gap: A wedge-block adjustment mechanism provides self-locking performance and precise gap control. The left and right adjustment handwheels allow users to set the rolling clearance according to the required material thickness.

• Direct Digital Indication: The sheet thickness and rolling gap are shown by digital gauges, making adjustment more precise, visible, and repeatable during setup and process development.

• Geared Two-Roll Transmission: Gear transmission directly drives the two rolls, providing a practical and stable rolling mechanism for laboratory-scale material reduction and densification.

• Vertical Feeding Configuration: The vertically positioned rolls make it convenient to introduce sheet and strip materials into the rolling zone, supporting efficient handling in compact laboratory workspaces.

• Adjustable Rolling Thickness: The rolling gap is adjustable from 0 to 2 mm. This range enables controlled thickness reduction and process comparison across different battery material formulations.

• Controlled Feed Speed: Feed speed can be adjusted from 0 to 40 mm/s, helping researchers coordinate material handling with rolling conditions and evaluate the effect of processing speed.

• Compact Electric Operation: Electric operation simplifies routine use, while the compact form factor supports flexible deployment in battery laboratories, materials research facilities, and pilot development areas.

• Protected Drive Components: The gear transmission is equipped with protective covers and hazard markings. These features help limit access to moving drive components during normal operation, subject to proper laboratory safety procedures.

Applications

Technical Specifications

The 100 mm, 200 mm, and 300 mm configurations share the same 100 mm roll diameter, ≤±2 µm roll cylindricity, HRC62 roll hardness, 0 to 2 mm adjustable rolling thickness, vertical roll placement, and 0 to 40 mm/s feed speed. Selection should be based primarily on the required sheet rolling width and available laboratory space. The wider configurations provide greater working coverage, while the narrower configuration offers a smaller external footprint for limited bench or floor areas.

For routine preparation, the roll surfaces should be carefully wiped with a soft cloth moistened with alcohol before each operation. Gear transmission areas should be lubricated to maintain smooth movement. Compressed-air cleaning should not be used because dust may enter the bearings and affect operating precision. When the unit will remain unused for an extended period, the rolls should be cleaned and coated with rust-preventive oil to protect the working surfaces from corrosion.

Regular inspection of screws, nuts, pins, and other fasteners is required to reduce the risk of loosening and maintain safe operation. When adjusting the roll gap, both handwheels should be moved evenly to avoid damage to internal components. After the adjustment is complete, the digital gauge may be removed to prevent accidental impact during production use.

Operators must keep hands and other body parts away from the roll and gear-transmission hazard zones during operation. The machine is intended for operation by one person at a time. Protective covers and hazard markings are provided around the gear transmission, but they do not replace established laboratory safety procedures. When wiping the rolls, the operator should stand behind the operating side and prevent the cloth or hands from becoming caught in moving parts. Gloves must not be worn when wiping rotating equipment.

Operators should wear close-fitting clothing, and personnel with long hair should wear a suitable cap. External or unauthorized personnel should not dismantle or adjust the equipment. Electrical components must not be removed or modified without authorization. These operating and maintenance practices help preserve roll accuracy, protect the equipment, and support safe long-term use.

Why Choose This Product

• Precision Manufacturing: ≤±2 µm roll cylindricity, HRC62 hardness, and a 0.4 or better surface finish provide a strong foundation for consistent laboratory rolling results.

• Process Control: The self-locking wedge-block adjustment and digital gauge display make gap setting clear, precise, and repeatable across experimental batches.

• Durable Construction: Hard-chrome roll surfaces resist wear and rust, while geared transmission provides stable mechanical drive for repeated material-processing work.

• Configuration Flexibility: Three working-width options, from 100 mm through 300 mm, allow research teams to select capacity according to sample dimensions, process goals, and available workspace.

• Practical Laboratory Support: Standard adjustment tools, digital gauges, and a feeler gauge are included to support installation, setup, and routine operation.
