MSK-HRP-22 Vertical Hot Rolling Press features a pair of 100mm wide steel rollers with Asynchronous rolling speed control up to 200°C. The separated control unit features a touch-screen control panel to control the temperature and rolling speed of each roller, and display the rolling force during rolling The rolling press can be placed inside a glovebox with optional three KF40 portsIts vertical rolling position allows users to "gravity feed" flexible films and produces shear force during rolling. Such a compact calendar machine can be put in Ar gas glove box and is very useful for preparing flexible or dry battery electrode sheets for Li-ion / Solid-Air battery research SPECIFICATIONS Power AC 220V, Single phase, 50/60Hz, 1500 Watts Rollers Roller Size: 100 mm Dia. x 100mm W Effective Cylinder Width: 96mm Roller hardness: HRC 52 The thickness of rolling: 0~1.8 mm adjustable Warning: Never roll materials with hardness >40HRC because rollers are softened at 200. Optional: 2-3 layer vertical rolling machine is available upon request at an extra cost Roller Material: CrMoV Horizontal Setup Besides the vertical setup that is suitable for direct powder feeding and dry film formation (eg: graphite anode fabrication), the hot rolling press can also be set horizontally for dry cathode (eg: NCM811) shape formation and calendering. Note: The direct powder-to-dry cathode film is quite challenging since the pre-sheet formation by manual way is critical. After the initial film formation, repeatedly rolling press horizontally to get the desired dry cathode thickness. Temperature Control Two independent temperature controllers enable dual-zone temperature control for the front and rear rollers. Temperature range: RT - 200°C with 30segments programmable Temperature accuracy +/-5°C Max heating temp: 200°C 40HRC The rolling machine can be used in an Ar gas environment. Multi-step thickness calendaring needed: While calendaring the sample sheet, make each calendaring decrement of 0.02mm compared with the sheet's original thickness. Never calendaring decrement over 0.02mm compared with the original sheet thickness after each calendaring. Clean the roller surface before and after each rolling process. Lubricate the roller surface when the machine is planned for idle to avoid corrosion. It is not allowed to use any MTI product in any hazardous location, especially prohibited from using in Class I environments (flammable gases & vapor).
