This integrated design combines high-efficiency kneading with high-speed dispersion, employing a unique high-viscosity kneading and online dispersion process. This approach significantly enhances the solid content of positive and negative electrode slurry, dramatically reducing production costs of lithium battery and representing a crucial advancement in lithium battery slurry mixing technology.
Significantly Improve Kneading Dilution Efficiency
The high-speed rotor generates the primary kneading force, while the low-speed paddle with an opposite rotation direction interacts to keep materials continuously working in the high-speed kneading zone. Kneading time is reduced to just 1/4-1/3 of that required by traditional mixers. The opposite rotation shearing mechanism also greatly enhances dilution efficiency compared with mixers.
Dead-Angle-Free Kneading Dilution
The low-speed paddle covers all material areas in the tank, ensuring full participation in kneading. An efficient spray system at the top cleans the agitating paddle and powder adhering to the tank cover, accurately maintaining the slurry formulation ratio.
Reliable and Simple Structure
Compared to traditional stirring and kneading processes, this design is simplified, easy to maintain, and has low usage costs.
Laboratory Type
Small/Medium Test Type
Mass Production TypeThe system can be flexibly configured to accommodate on-site production conditions, facilitating efficient preparation of high-viscosity slurry.
Main materials are directly fed into the kneading machine through the ton-bag machine, while auxiliary materials are introduced via gravity feeding or pneumatic conveying. The kneading machine completes the mixing, kneading, and dilution processes. The diluted slurry then enters the online disperser for further dispersion, ensuring uniform and effective dispersion that meets customer requirements.
