100mm Laboratory Heated Electric Vertical Two Roll Mill Electric Rolling Roller Press

Product Overview

This 100mm laboratory heated electric vertical two roll mill is designed for controlled rolling of small quantities of battery materials, nonferrous metals, precious metals, and other research materials. Its motorized two-roll configuration provides adjustable rolling thickness, straightforward operation, and reversible movement for flexible laboratory processing. The equipment supports both heated and unheated operation, allowing researchers to match the rolling method to the material and process objective.

The system is particularly suitable for reducing lithium battery electrode thickness and increasing electrode density during cell material development. It also supports laboratory work involving copper, aluminum, limited quantities of gold and silver, and related materials science applications. Compact construction makes the unit practical for research laboratories, pilot-scale development, universities, and technical production environments where space and material quantities are limited.

High-hardness, hard-chrome-plated rolls provide a durable working surface with corrosion resistance and a specified hardness of HRC62. Independent upper and lower temperature control, digital readouts, fine gap adjustment, and digitally displayed feed speed help users maintain repeatable processing conditions. The equipment is built for precise, consistent operation during demanding development and sample preparation work.

Key Features

• Independent Heated Rolling: The upper and lower rolls are heated independently from room temperature to 130°C, allowing operators to establish process-specific thermal conditions for different materials and rolling requirements.

• Accurate Temperature Regulation: Digital temperature displays show the set value and detected value separately. Temperature control accuracy is specified at ±0.5°C, with a resolution of 0.1°C for close process monitoring.

• High-Hardness Roll Surface: The rolls are manufactured with high hardness and finished with hard chrome plating. The specified HRC62 hardness supports wear resistance, while the plated surface helps protect against rust and maintain a dependable working condition.

• Precision Roll Geometry: Roll cylindricity is specified at ≤±2 µm, supporting uniform material compression and consistent thickness across the working width.

• Fine Mechanical Gap Adjustment: A wedge adjustment mechanism provides self-locking behavior and precise gap control. Dual handwheels allow the operator to adjust the roll gap, while digital dial indicators provide direct dimensional feedback.

• Adjustable Rolling Thickness: The rolling gap and resulting sheet thickness can be adjusted from 0 to 2 mm. This range supports controlled reduction and density improvement during battery electrode and materials research.

• Digital Feed Speed Control: Feed speed is adjustable from 0 to 40 mm/s and displayed digitally, enabling operators to observe and set the rolling speed accurately for repeatable process trials.

• Motorized Forward and Reverse Operation: Electric drive provides automated roll rotation in both directions. Reversible operation improves handling flexibility and allows the operator to adapt the rolling sequence to the material and laboratory workflow.

• Compact Laboratory Construction: The vertical roll arrangement and compact dimensions provide a small equipment footprint without sacrificing the adjustment and monitoring functions needed for controlled laboratory rolling.

• Flexible Heated or Unheated Processing: Operators can select heated or unheated operation, making the unit suitable for temperature-sensitive materials, room-temperature rolling, and controlled thermal rolling experiments.

Applications

Technical Specifications

The rolling process is performed by placing the material between the two rolls and pressing the start button. The motor drives the gears, which rotate the rolls to produce the rolling action. Forward and reverse rotation can be selected according to the sample and operating sequence.

The roll gap is adjusted through the wedge mechanism by turning the left and right adjustment handwheels evenly. The self-locking adjustment design helps maintain the selected position, while the dial indicator provides a direct and convenient reading. After the gap has been set, the dial indicators can be removed to reduce the risk of accidental impact during production use.

Temperature settings are entered through the temperature controllers. The green digital display indicates the set temperature, while the red digital display indicates the detected temperature. Operators can adjust the set value using the up and down keys. The upper and lower rolls can be configured independently from room temperature to 130°C, providing greater control over heated rolling conditions.

Routine maintenance is important for preserving roll accuracy and equipment performance. Before each operation, clean both roll surfaces carefully with a soft cloth moistened with alcohol. Apply lubricant to the gear drive areas to maintain smooth movement. Do not use an air pump for cleaning, because dust may enter the bearings and affect operating precision. When the equipment will remain unused for an extended period, clean the roll surfaces and apply rust-preventive oil to protect the working surfaces from corrosion.

Periodically inspect screws, nuts, pins, and other fasteners to prevent loosening and reduce the risk of equipment or personal injury. Adjust both sides of the roll gap evenly to avoid damage to other components. The geared transmission areas are fitted with protective covers and hazard markings, but operators must still keep hands and other body parts away from the rolls and transmission zones during operation. Only one trained operator should operate the equipment at a time.

When wiping the rolls, stand behind the operating surface and take precautions against cloth or hands being drawn into rotating components. Never wear gloves while wiping rotating machinery. Operators should wear close-fitting clothing, and personnel with long hair should wear a protective cap. Unauthorized personnel should not dismantle or adjust the equipment, and circuit components must not be removed without authorization. The stainless steel guard can become hot during operation; avoid direct contact and use appropriate heat precautions.
