30L Vacuum Planetary Mixer
In the fields of new energy batteries, sealants, adhesives, cosmetics, and high-viscosity chemical materials, pilot-scale production capacity combined with precise mixing control is essential for process development and small-batch manufacturing. Wuxi Maxwell Automation Technology Co., Ltd., with over 18 years of industry experience, offers the 30L Vacuum Planetary Mixer (Model: SXJ-30) – a versatile pilot-scale device integrating high-torque mixing, high-speed dispersion, and vacuum degassing, specifically designed for pilot production and small-batch manufacturing of sealants, adhesives, battery slurries, cosmetics, and other high-viscosity materials with viscosity ranging from 5,000 to 1,000,000 cP. The SXJ-30 is a CE-certified medium-sized unit with a highly efficient 30-liter container and complete accessories for immediate use.
Working Principle: Planetary Motion, High-Speed Dispersion, and Vacuum Environment
The "double planetary" mixer derives its name from its unique motion pattern. During operation, the low-speed mixing blades and high-speed dispersion disc rotate around the mixing vessel's central axis (revolution) while simultaneously rotating on their own axes (rotation). This compound motion generates strong shearing and kneading forces, causing materials to circulate comprehensively and achieve uniform mixing at both macro and micro levels.
The high-speed disperser (up to 2980 rpm) creates intense shear forces that break down agglomerates and ensure thorough dispersion of fillers, pigments, and additives – critical for battery slurries, sealants, and adhesive formulations.
The integrated vacuum system (achieving a vacuum level down to -0.09 MPa) effectively removes air bubbles entrapped during mixing. This is particularly important for sealants, adhesives, battery slurries, and electronic potting compounds where bubbles can compromise product integrity, electrical insulation, or bond strength. The vessel adopts a special sealing structure, capable of pressurized and vacuumized mixing, with excellent exhaust and bubble removal effects.
The pilot-scale design (30L working volume) makes this model ideal for process development, scale-up trials, and small-batch production, bridging the gap between laboratory R&D and full-scale manufacturing.
