Dual-Servo Differential-Speed Heated Horizontal Roller Press XN-HRPE200-W

Name: Dual-Servo Differential-Speed Heated Horizontal Roller Press XN-HRPE200-W

Equipment Type: Laboratory Dual-Servo Differential-Speed Heated Horizontal Roller Press with Asynchronous Top/Bottom Roller Drive, Independent Dual-Zone Heating, Powder Feeding Hopper & PLC Touch Screen Control

Product Code: XN-HRPE200-W

Product Introduction:

The Dual-Servo Differential-Speed Heated Horizontal Roller Press XN-HRPE200-W is designed for motorized rolling of battery materials and other non-ferrous materials under controlled temperature conditions in laboratory environments. It is particularly suitable for the thinning and densification of clean-energy material lithium-ion battery electrode sheets. Unlike conventional roller presses where both rollers rotate at the same speed, the XN-HRPE200-W features dual-servo control with asynchronous (differential-speed) rotation — the top and bottom rollers can be set to different speeds independently — enabling advanced calendering processes that benefit from shear or differential compression. The machine includes an adjustable-width feeding hopper for powder material input and double scrapers beneath the rollers for residue removal, with independent dual-zone heating up to 150 °C.

Main Features:

• Dual-servo control with asynchronous differential-speed rotation — top and bottom roller speeds independently adjustable, enabling shear-rolling and differential compression processes
• Dual-zone independent heating with digital display — top and bottom rollers controlled independently up to 150 °C with ±2 °C accuracy
• Roller internal heating design — precise temperature control at the roller surface
• Heating is optional — operate with or without heating depending on process needs
• Adjustable-width feeding hopper — convenient for powder-form material input
• Double scrapers beneath rollers — removes residue and improves surface finish
• Hard rollers with chrome-plated surface — hardness up to HRC62, with rust-resistant chrome plating
• Wedge-block gap adjustment — excellent self-locking, high adjustment precision, electronic indicator display
• High rolling precision — roller cylindricity ≤ ±2 μm
• Digital display of sheet thickness and feed speed — precise observation and adjustment
• Motorized operation with forward/reverse capability — enables automated rolling and sample retrieval
• PLC + touch screen control — convenient automated parameter setting
• Compact footprint with refined industrial design — easy and flexible operation for laboratory use

Technical Parameters:

Values measured by Xnergy. Typical values for reference; not guaranteed unless otherwise specified.

Application Areas:

• Lithium-ion battery electrode sheet thinning and densification — both dry-method and wet-method electrode rolling, with optional heating up to 150 °C
• Powder-material calendering — direct compression of powder-form materials fed through the adjustable-width hopper
• Differential-speed (shear) calendering research — processes that benefit from asymmetric top/bottom roller speeds, useful for membrane-electrode assemblies, dry-method electrodes, and other shear-sensitive material systems
• Clean-energy battery material laboratory rolling experiments where temperature, differential speed, or shear improves electrode density, adhesion, or microstructure
• Coin-cell, pouch-cell, and prismatic-cell laboratory electrode preparation
• Non-ferrous material laboratory hot rolling

Recommended Operating Procedure:

1. Place the XN-HRPE200-W machine body on a stable laboratory benchtop or workstation with adequate working space; position the external electrical cabinet nearby. Connect the power supply per local electrical standards. 2. Power on the unit and verify the dual servo motors, gear-drive mechanism, dual heating zones, digital displays (temperature, speed, gap), wedge-block gap adjustment, feeding hopper, double scrapers, and PLC touch screen are all in good condition and operating normally. 3. Decide whether to operate with or without heating. If heating is required, set the target temperature independently for the top and bottom rollers on the dual temperature controllers (within ambient–150 °C, ±2 °C accuracy, 0.1 °C resolution). Allow both rollers to reach and stabilize at their setpoints. 4. Set the target roller gap by rotating the left/right gap-adjustment hand wheels evenly; read the gap value on the electronic indicator (target range 0–2 mm). 5. On the PLC touch screen, configure the target speed for the top and bottom rollers independently (synchronous if equal speeds are desired, asynchronous/differential if shear rolling is desired). Set feed speed within the 0–40 mm/s range. 6. For sheet/strip rolling: place the electrode sheet (≤ 200 mm wide) between the two horizontally-placed heated rollers. For powder rolling: adjust the feeding hopper width and load the powder material. 7. Toggle the forward/reverse selector to the forward position and start the motors; both rollers rotate at the configured (synchronous or differential) speeds, performing paired-roller hot or ambient compression. The double scrapers beneath the rollers remove any residue. 8. As the calendered material exits the rollers, support it gently to avoid wrinkling; allow heated material to cool before further handling. 9. If multiple calendering passes are required to reach the target final thickness, gradually reduce the roller gap between passes and repeat the procedure. 10. After use, allow the heating system to cool, then power off the unit; clean the roller surfaces, scrapers, feeding hopper, and frame with a soft, clean cloth dampened with alcohol. Inspect the rollers, servo motors, heating elements, scrapers, and digital displays periodically.

Maintenance:

• Frequently wipe the machine with a soft cloth dampened with alcohol to keep it clean
• Lubricate moving parts with oil to keep movement smooth
• If the machine will not be used for an extended period, wipe down the surface of moving components and apply a protective rust-prevention oil
• Periodically inspect screws, nuts, pins, and other fasteners across all parts of the machine to prevent loosening, avoiding equipment-quality issues and personal-safety incidents

Packaging & Storage:

The XN-HRPE200-W ships with the machine body (L770 × W320 × H450 mm) and an external electrical cabinet (L450 × W400 × H380 mm). The machine body includes Φ96 mm hard-chrome-plated rollers (horizontal layout), dual servo motors with planetary reducers, dual independent roller internal heating systems with independent digital temperature controllers (top + bottom, ambient–150 °C, ±2 °C), adjustable-width feeding hopper, double scrapers beneath the rollers, wedge-block gap-adjustment mechanism with self-locking, electronic gap indicator, digital speed/thickness display, and PLC + touch screen control. Install on a stable laboratory benchtop or workstation in a clean, dry environment, away from corrosive atmospheres and moisture. Disconnect the power supply when the equipment is not in active use. After each use, allow the heating system to cool to room temperature, then clean the roller surfaces, scrapers, feeding hopper, gears, and frame; apply rust-prevention oil to the roller surfaces if the machine will not be used for an extended period. Inspect the rollers, servo motors, planetary reducers, heating elements, scrapers, feeding hopper, digital displays, and gap-adjustment mechanism periodically for wear, contamination, or signs of degradation.

Safety:

For research and industrial laboratory use only. During operation, do not insert hands or any other body parts into the roller-engagement area, the gear-drive area, the feeding hopper, or any moving components to prevent personal injury. Operation by two or more persons simultaneously is not allowed to avoid accidental injury. Do not touch the heated rollers or roller surfaces immediately after the run — surface temperatures up to 150 °C can cause severe burns. When wiping roller surfaces during operation, stand at the operator side and wipe carefully; prevent wipes and hands from being caught in the rollers. Never wear gloves when wiping rotating components. External (third-party) technical personnel and unauthorized persons must not disassemble the equipment under any circumstances. Always wear appropriate PPE (safety glasses, high-temperature gloves, lab coat, close-fitting sleeves) when operating the heated roller press. Keep loose clothing, hair, and jewelry away from the rotating rollers, gears, and motors. When handling battery electrode sheets or powders that may have absorbed solvent residues or contain reactive materials, wear chemical-resistant gloves and operate in a well-ventilated area. Press the emergency stop or power off the unit immediately if any binding, unusual resistance, abnormal motor sound, smoke, or damage to the material is observed. Allow the heating system to cool to room temperature before any cleaning, maintenance, or component replacement. Disconnect the power supply before any service work. Refer to the included user manual for complete safety and operating instructions.
