Integrated Dual Servo Heated Horizontal Rolling Press Calender Machine

Product Overview

This system is an integrated dual-servo heated horizontal rolling press engineered specifically for high-precision calendering of battery electrodes and non-ferrous advanced materials. Operating under controlled thermal conditions, the machine facilitates precise thickness reduction and density optimization for next-generation lithium-ion battery electrodes, supercapacitors, and specialized energy storage substrates. By integrating independent dual-servo drives and internal roller heating, this equipment delivers superior structural uniformity across both dry-process and wet-process electrode films.

Designed for laboratory research environments, pilot production facilities, and advanced materials development centers, the calender provides adaptable operation for continuous foil processing, pellet compaction, and strip rolling. The horizontal roller orientation paired with a dedicated powder feeding hopper enables researchers to handle loose active material formulations as well as continuous coated substrates with consistent feeding geometry and reduced material distortion.

Built to rigorous industrial standards, the equipment ensures uncompromised mechanical rigidity and thermal stability during extended rolling trials. High-grade alloy rollers treated with specialized hard chrome plating resist deformation and wear under sustained compressive stress. With integrated digital instrumentation and self-locking micrometric clearance adjustment, researchers can rely on this calender for highly repeatable, publication-grade experimental runs.

Key Features

• Dual Servo Independent Asynchronous Drive: Upper and lower rollers are driven by dedicated servo motors, allowing operators to freely synchronize rotational speeds or introduce differential asynchronous rotation to tailor interfacial shear stresses and density gradients within sensitive electrode layers.
• Internal Precision Thermal Management: Integrated internal heating elements within both rollers provide uniform surface heat distribution up to 130°C, managed by independent dual digital PID controllers with 0.1°C display resolution and ±2°C temperature accuracy.
• Versatile Dual-Mode Heating Operation: The calender operates seamlessly in either heated rolling or ambient cold pressing modes, giving research teams the flexibility to evaluate thermal compaction dynamics without reconfiguring mechanical hardware.
• Ultra-Rigid Chromium-Plated Tooling: Engineered with high-strength alloy rollers hardened to HRC62 and finished with hard chrome plating, achieving superior surface finishes (Ra 0.8 μm for dry electrode pressing and Ra 0.4 μm for wet electrode coating) to prevent film adhesion and contamination.
• High-Precision Roller Cylindricity: High-accuracy machining ensures roller cylindricity tolerances within ≤ ±2 μm, guaranteeing uniform cross-sectional compaction, preventing local stress concentrations, and eliminating thickness variance across wide substrates.
• Wedge-Block Micrometric Gap Adjustment: Calibrated wedge-block mechanisms provide self-locking mechanical stability and zero-backlash clearance adjustment from 0 to 3 mm, monitored in real time via high-precision digital electronic gauges.
• PLC Touchscreen Automation & Reversible Direction: Centralized PLC interface provides intuitive digital parameter programming, stepless feeding velocity adjustments from 0 to 40 mm/s, and instantaneous forward/reverse rolling control for rapid sample retrieval and automated cycles.
• Powder Processing Feed Hopper: Includes an integrated powder feeding funnel and guide plate assembly, enabling clean and controlled direct rolling of loose dry-process electrode powders, solid-state electrolytes, and granular metallurgical formulations.

Why Choose This Product

• Unmatched Asynchronous Calendering Control: Unlike conventional single-motor calenders that lock roller ratios, this system uses dual independent servo motors to introduce controlled surface velocity differentials, enabling specialized shear-induced binder fibrillization and stress relief during advanced electrode manufacturing.
• Superior Thermal and Mechanical Uniformity: With internal heating elements embedded directly inside the rollers and cylindrical machining tolerances held to ≤ ±2 μm, the equipment eliminates edge-to-center thermal gradients and compressive irregularities, ensuring superior repeatability across continuous runs.
• Robust Self-Locking Mechanical Integrity: The precision inclined wedge-block gap adjustment mechanism eliminates deflection and drift under sustained rolling forces, securing exact gap settings through high-resolution digital indicators without unexpected back-off.
• Compact Laboratory Footprint with Industrial Rigidity: Engineered into an integrated desktop architecture, the unit provides industrial-grade HRC62 hardened chrome tooling, advanced PLC programmability, and versatile powder/strip feeding within an efficient 770 mm × 540 mm footprint.
• Comprehensive Process Versatility: Capable of dry-film rolling, wet slurry electrode densification, heated solid-state membrane consolidation, and ambient foil sizing, this calender serves as a multi-role asset for progressive clean energy laboratories.
