150 x 200 mm Laboratory Heated Rolling Mill Electrode Sheet Two Roll Mill

Product Overview

This heated two-roll rolling mill is designed for small-scale lithium electrode calendaring in laboratory and trial-line environments. A reduction motor drives high-hardness rolls while a mechanical gap adjustment applies controlled compression to electrode sheets. The process reduces sheet thickness and increases electrode density, giving researchers a practical route to evaluate calendaring conditions before broader process deployment.

The equipment is suited to battery-material laboratories in universities and enterprises, particularly where electrode plates require thinning and densification for clean-energy research. Its 200 mm maximum working width supports laboratory electrode-sheet formats, while the 0-3 mm adjustable effective gap accommodates different starting thicknesses and rolling objectives. Both rolls can be temperature controlled independently and adjusted freely, allowing the operator to establish the thermal conditions required for the workpiece.

Beyond lithium battery plates, this unit is intended for manual rolling of small quantities of gold, silver, copper, aluminum, and other non-ferrous materials. The combination of heated rolls, HRC62 roll-surface hardness, precise roll geometry, adjustable line speed, and 15T maximum pressure makes it a focused laboratory tool for controlled material densification and thickness reduction under demanding research conditions.

Key Features

• Independent Roll Temperature Control: The two rolls can be controlled independently and adjusted freely. This supports thermal setup flexibility when processing lithium electrode sheets and small quantities of metal materials requiring heated rolling.

• Heated Rolling Capability: Roll temperature is approximately 150°C, enabling thermal assistance during the rolling process. This capability is especially relevant to laboratory work on battery materials and to manually rolled precious or non-ferrous metals.

• Precision Mechanical Gap Adjustment: A mechanically adjusted effective gap of 0-3 mm lets the operator set the roll separation for the desired compression condition. The adjustment directly supports controlled electrode-sheet thinning and density increase.

• High-Hardness Roll Surface: The pressure rolls have an HRC62 surface hardness and a 5 mm roll-surface hardening depth. This construction is specified for repeated laboratory rolling work where the roll surface is a critical process-contact component.

• Accurate Roll Geometry: Roll cylindricity is specified at <= +/-2 micrometers. This precision characteristic helps provide a stable rolling interface across the working width for material research and trial-line processing.

• Variable Rolling Speed: Stepless speed control provides an adjustable line speed of 0-6.0 m/min. Researchers can set a rolling pace appropriate to the material and the laboratory process being evaluated rather than working at a single fixed speed.

• Laboratory-Scale Working Width: A maximum working width of 200 mm aligns the system with compact electrode-sheet and materials-research workflows. The format is suitable for university laboratories and enterprise experimental lines using small-scale samples.

• High Compression Capacity: With a maximum pressure of 15T, the equipment combines laboratory dimensions with substantial rolling force. This capacity supports densification and forming of electrode sheets through pressure applied by the driven rolls.

• Reduction-Motor Drive: A reduction motor drives the high-hardness pressure rolls. The drive arrangement is integral to the equipment's working principle, transferring motion to the rolls while the mechanical setting establishes the required roll gap.

Applications

Technical Specifications

The specification set centers on the rolling interface and the variables that affect laboratory operation. The pressure rolls measure Phi150mm x 200mm, and the stated maximum working width is 200mm. This relationship makes the unit appropriate for sheet material that must be processed across a defined laboratory width rather than through a large production-scale rolling path.

Roll separation is set mechanically. The effective gap can be adjusted from 0 to 3 mm, so the operator can establish the compression condition according to the starting material and the intended result. The equipment's operating principle is based on material being pressed and formed between the rolls, increasing the compactness of electrode sheets. The gap setting is consequently a central process parameter for electrode thinning and densification work.

Temperature and speed are also operator-adjustable process variables. The roll temperature is approximately 150°C, and the two rolls can be independently controlled and adjusted freely. Speed is steplessly adjustable, with a line-speed range of 0-6.0 m/min. These stated controls allow laboratory teams to change thermal and movement conditions during research work without treating the rolling operation as a single fixed setting.

The roll construction data emphasize hardness and geometry. The specified HRC62 roll-surface hardness, 5 mm surface hardening depth, and <= +/-2 micrometers cylindricity define the supplied rolling components. Alongside a maximum pressure of 15T, these values describe a laboratory system intended to apply substantial compression through high-hardness rolls. The reference materials do not state a numerical roll-surface finish; it is therefore identified as unspecified rather than assigned an unsupported value.

Power is listed as 220V, 4KW. The source material also identifies single-phase 220V power for use in university and enterprise experimental lines. Users should assess their available electrical supply, their material format, the required rolling conditions, and their laboratory procedure against the listed specifications when defining a suitable process setup.
