200x300mm Laboratory Heated Calender Battery Electrode Roll Press Electrode Sheet Roll Press

Product Overview

This heated roll press is designed for small-scale lithium battery electrode calendering, providing controlled compression to reduce electrode thickness and increase compact density. A reduction motor drives high-hardness pressure rolls, while mechanical adjustment of the roll gap lets operators set the forming clearance for the material under process. The equipment combines heated rolling, adjustable line speed, and substantial pressing force for laboratory work that requires repeatable mechanical densification.

The system is suited to university laboratories and enterprise trial lines working with clean-energy materials. Primary applications include lithium battery electrode plate thinning and densification, as well as manual rolling of small quantities of gold, silver, copper, aluminum, and other nonferrous materials. Its 300 mm maximum working width supports electrode-sheet development and material studies where roll contact, gap setting, and temperature are important process variables.

Built around hardened rolls with specified cylindrical accuracy, this unit is intended for demanding research use where uniform compression matters. Independent temperature control for the two rolls provides a practical way to set the thermal condition of each rolling surface. Adjustable clearance and stepless speed control give technical teams direct control of the main parameters affecting thickness reduction, density development, and rolling behavior.

Key Features

• Heated Dual-Roll Processing: The two pressure rolls can be temperature controlled independently and adjusted as required, with a stated roll temperature of 150°C. This configuration supports thermal rolling studies where heat is used alongside mechanical compression.

• 300 mm Working Width: A maximum working width of 300 mm accommodates laboratory-scale battery electrode sheets and small metal stock. The roll dimensions of Φ200 mm × 300 mm provide a substantial contact surface for controlled sheet processing.

• Adjustable Roll Clearance: The effective gap is mechanically adjustable from 0-4 mm. Operators can set the clearance to suit material thickness and the intended degree of compression without changing the fundamental rolling arrangement.

• High Pressure Capability: Maximum pressure is specified at 15T, giving the equipment the force capability required for electrode compaction and thickness reduction. This is a key consideration for materials teams seeking to increase electrode compact density through calendering.

• Stepless Variable Speed: Line speed is continuously adjustable from 0-4.0 m/min. The variable-speed arrangement enables operators to select a rolling rate appropriate to the material, heating condition, and research procedure.

• Hard, Deep-Hardened Roll Surface: The roll face has HRC62 hardness and a stated quench depth of 10 mm. These characteristics are important for a pressure-contact component used in repeated laboratory rolling operations.

• Precision Roll Geometry: Roll cylindrical accuracy is specified as ≤±2 μm. This controlled geometry supports consistent roll engagement across the working width, an important factor when evaluating calendered electrode sheets and thin material samples.

• Reduction-Motor Drive Principle: A reduction motor drives the high-hardness pressure rolls, while the gap is adjusted mechanically. The direct, understandable operating principle gives laboratory users practical control over the rolling process and its principal settings.

• Research-Oriented Material Versatility: Beyond lithium battery electrode plates, the equipment is intended for manual rolling of limited quantities of precious metals and nonferrous materials, including gold, silver, copper, and aluminum. This extends its relevance across battery research and materials-development laboratories.

Applications

Technical Specifications

The supplied reference material contains two electrical statements: the overview identifies a single-phase 220V supply, while the technical parameter list specifies 380V、6KW. Confirm the required electrical configuration for the intended installation before procurement, commissioning, or facility planning.

For process planning, the central adjustable inputs are roll temperature, roll clearance, line speed, and applied pressure. The stated design allows the two rolls to be controlled independently for temperature, while the effective gap is adjusted mechanically. This gives researchers a defined framework for comparing material behavior across different thermal and compression conditions.

The pressure rolls are specified at Φ200 mm × 300 mm, with a maximum working width of 300 mm. For buyers evaluating electrode-sheet format, the relevant distinction is between the physical roll size and the usable processing width. The stated 300 mm width is the limit to assess against the planned electrode-sheet dimensions.

The roll construction data are also significant for laboratory teams that need stable rolling contact. HRC62 roll-face hardness, a 10 mm quench depth, and cylindrical accuracy of ≤±2 μm describe the pressure-roll characteristics supplied for this system. These values should be considered alongside the planned material type, sheet condition, temperature setting, and desired final thickness.

Why Choose This Product
