Laboratory Manual Vertical Double Roller Mill Manual Rolling Press with Two 100 mm Rollers

Product Overview

This laboratory manual vertical double roller press is designed for controlled rolling and thickness reduction of battery materials, particularly lithium battery electrode sheets. Two high-hardness rollers apply opposing force through gear-driven rotation, while the adjustable rolling gap enables practical control over sheet thickness and material density. The compact vertical format supports direct feeding of sheet and strip materials between the rollers.

The equipment is available for laboratory rolling widths from 0 to 100 mm or 0 to 200 mm. It is suitable for battery R&D, clean-energy materials research, powder processing studies, materials science laboratories, and academic development work requiring repeatable manual densification. Operators control the rolling speed through the hand crank, making the unit responsive for small-batch experiments and process development.

A rigid mechanical structure, precision-finished rollers, protective gear covers, and straightforward adjustment system support dependable laboratory operation. The rollers provide a cylindrical accuracy of ≤±2um, surface hardness of HRC62, and surface finish of 0.4以上. These characteristics help maintain stable contact conditions and consistent results during demanding research workflows.

Key Features

• High-Hardness Chromium-Plated Rollers: The rollers are treated with hard chromium plating for corrosion resistance and a hardness of HRC62. This robust surface helps resist wear during repeated material rolling and supports long service life.

• Precision Cylindrical Accuracy: Roller cylindricity is ≤±2um, helping maintain uniform pressure distribution across the working width. Consistent roller geometry supports more even electrode thickness and material density.

• Self-Locking Gap Adjustment: A wedge adjustment mechanism controls the rolling gap with strong self-locking performance. Operators can adjust both sides using the handwheels and read the setting directly from the digital gauges.

• Adjustable Rolling Thickness: The rolling gap is adjustable from 0 to 2mm, allowing users to develop thickness-reduction and densification procedures for different battery material formulations and sheet conditions.

• Gear-Driven Opposing Rotation: Intermeshing gears drive the two rollers together for stable counter-rolling. The mechanical transmission provides direct, efficient force transfer during manual operation.

• Vertical Roller Arrangement: The vertical layout makes it convenient to feed sheet and strip materials into the nip. It also provides a compact footprint for benchtop laboratory environments.

• Manual Speed Control: Rolling speed is determined by the operator’s hand-crank rotation and can reach 0 to 40mm/s. This gives researchers immediate control over material handling and pass-by-pass process conditions.

• Compact and Flexible Operation: The equipment combines a small footprint with simple manual controls, making it practical for laboratories that need fast setup, flexible experimentation, and easy access to the rolling zone.

• Protected Transmission System: Gear-driven areas are fitted with protective covers and hazard markings. This helps separate the operator from moving transmission components during normal use.

Applications

Technical Specifications

The product family is identified below using the site-facing identifiers DG04-100 and DG04-200, derived from the available roller-width variants.

The two rollers use gear-meshed rotation to perform opposing rolling. During operation, the material is placed between the rollers and the hand crank is turned manually to drive the rolling process. The rolling gap is adjusted by rotating the left and right handwheels through the wedge mechanism. Both sides should be adjusted evenly to protect the adjustment system and maintain alignment. The digital gauges provide direct, convenient readings during setup.

Standard configuration includes one set of hexagonal socket wrenches, two digital gauges, and one feeler gauge. These accessories support initial adjustment, inspection, and routine laboratory operation.

For reliable performance, wipe both roller surfaces carefully with a soft cloth moistened with alcohol before each operating session. Lubricate the gear transmission areas to maintain smooth movement. Do not use an air pump for cleaning, because dust may enter the bearings and affect operating accuracy. When the unit will remain unused for an extended period, clean the roller surfaces and apply rust-preventive oil to protect them from corrosion.

Regularly inspect screws, nuts, pins, and other fasteners for looseness. During gap adjustment, turn both small handwheels evenly. After the gap is set, the digital gauge may be removed to prevent accidental impact or damage during production use. Operators should follow the supplied safety markings and operating procedures at all times.

The rolling zone and gear transmission hazard areas must remain clear during operation. Hands and other body parts must never enter these areas. Only one person should operate the equipment at a time to reduce the risk of accidental injury. When wiping the rollers, stand behind the operating side and prevent the cleaning cloth or hands from being drawn into moving parts. Never wear gloves while wiping rotating machinery. Operators should wear close-fitting clothing, and personnel with long hair should wear a protective cap. External or unauthorized personnel must not disassemble or adjust the equipment.
