15L Vacuum Double Planetary Mixer with Touch Screen
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 15L Vacuum Double Planetary Mixer with Touch Screen – a versatile pilot-scale device integrating high-torque mixing, high-speed dispersion, vacuum degassing, and intelligent PLC control with touch screen interface, specifically designed for pilot production and small-batch manufacturing of sealants, adhesives, battery slurries, cosmetics, and other high-viscosity materials .
Working Principle: Planetary Motion, High-Speed Dispersion, Vacuum Environment, and Intelligent Control
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 precision-machined clearances between the blades and between the blade and the mix tank's inner walls provide a strong shearing force, resulting in superior mixing, kneading, and dispersion .
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 touch screen control system is a key feature of this model. With PLC intelligent control and HMI touch screen interface, operators can easily set and monitor mixing parameters, including multi-stage speed settings, mixing time, and temperature. The system also provides motor overload protection and various electrical safety features .
The lifting cap system allows the vessel cover to be raised and lowered hydraulically. Furthermore, the stirrers and scraper can rise with the beam and fully detach from the vessel body, facilitating easy feeding, sampling, and cleaning .
