AOT-MSK-BPC-DF200 is a three-roller continuous hot rolling press with various speeds to prepare a lithium-ion battery's dry electrode and solid-state electrolyte sheet. Three pairs of rolls can be independently controlled under a pressure of 8T Max.
AOT-MSK-BPC-DF200 three-roll continuous hot rolling press is specially designed for lithium-ion battery dry electrodes and solid electrolyte sheets. It is equipped with three sets of hardened Cr12MoV rollers (HRC58-62, roll seam accuracy ±2.5μm) with independent temperature control (200℃), pressure control (15T/roll) and speed control (0.3-2m/min) to support the continuous roll pressing of 200mm wide materials. High-precision continuous roller pressing. The hot rolling press adopts single-phase 220V power supply (5kW power consumption), single-roll pressure resolution ±0.30kg, and can accurately regulate electrode porosity and electrolyte sheet densification (density fluctuation ≤1.2%). Independent PID control of roll surface temperature (±1℃), suitable for thermal activation of dry electrode binder and crack-free molding of solid electrolyte brittle materials. The whole machine size is 1200×680×1400mm (net weight 600kg), compatible with 25±3℃ clean workshop environment, providing efficient solutions for solid state battery pilot line and dry electrode mass production.

FAQ
Q1: How to ensure the temperature uniformity with three independent temperature control rolls of hot rolling press?
A: Each roll is integrated with dual-zone infrared temperature measurement and closed-loop heating module, the temperature difference of the whole roll surface is ≤±1℃, avoiding the deterioration of the performance caused by localized overheating of the material.
Q2: What is the wear resistance of Cr12MoV rollers?
A: The surface hardness is HRC58-62, with nitriding treatment process, it can continuously roll the dry electrode material for >5000 hours, and the wear amount is <0.01mm.
Q3: How to avoid cracking of solid electrolyte sheet by rolling?
A: The hot rolling press is recommended to pressurize gradually in stages (5T→10T→15T), synchronously increase the roll temperature to 150-180℃ to enhance the plasticity of the material, and control the roll speed below 0.5m/min.
Q4: What is the calibration frequency of roll seam accuracy ±2.5μm?
A: Calibrate once a month with laser range finder, daily can be verified by standard thickness sheet (e.g. 2.000mm) pre-pressing, when the deviation exceeds ±3μm, it is necessary to adjust the servo positioning module.
Q5: Does the hot rolling press support ultra-thin (<50μm) electrode rolling?
A: The minimum roll gap can be adjusted to 10 μm, suitable for 50 μm electrode production, with online thickness monitoring system (optional) real-time feedback to adjust the pressure.
