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.
It is not easy to introduce every aspect of the high-speed disperser, so we have prepared a lot of information on this page for you to learn more. To ensure that you can quickly find the information you need, we have prepared this table of contents, and when you click it, it will jump to the corresponding location.
It can be flexibly configured according to on-site production conditions to achieve efficient preparation of high-viscosity slurry. The main materials are directly put into the kneader through the ton bag machine, and the auxiliary materials are put into the kneader through gravity dropping or pneumatic conveying. The kneader can complete the mixing, kneading and dilution processes. The diluted slurry enters the online disperser for further dispersion, achieving uniform and effective dispersion of the slurry to meet customer requirements. The high-viscosity kneading process can significantly increase the solid content of positive and negative electrode slurries and significantly reduce the production cost of the entire lithium battery line. Shangshui can provide high-viscosity kneading process pulping production lines with capacities of 100L/h, 300L/h, 1000L/h, and 1500L/h depending on the production capacity.

The high-speed rotor generates the main kneading force, which interacts with the low-speed blades in the opposite direction, so that the material always works in the high-speed kneading range, and the kneading time is only 1/4-1/3 of that of the traditional mixer. Thanks to the shear mechanism with opposite rotation direction, the dilution efficiency is also far superior to that of the mixer.
Compared with the traditional mixing and kneading process, the structure is simple, maintenance is convenient, and the use cost is low.
The system is designed for the efficient production of lithium battery slurry and is suitable for the preparation of positive and negative electrode materials for lithium batteries. The preparation of these materials is crucial to battery performance, so the system plays an important role in lithium battery manufacturing.
In addition to lithium batteries, this type of efficient mixing system can also be used for the preparation of other high-viscosity slurries and is suitable for the mixing and dispersion of chemical raw materials.
The system’s efficient mixing capabilities are also suitable for the production of ceramic and metallurgical materials, which usually require uniform material mixing to ensure product quality.
The intelligent design of the system allows multiple formulas to be produced simultaneously, reducing manual intervention and improving production efficiency and product quality.
We started to solve the systematization of the front-end equipment in the production process of lithium-ion batteries in 2013, and have been recognized by the market after years of practice and successful cases. Our equipment is not limited to the new energy industry, and the powder conveying and pulping systems have a large market space in the fields of medicine, food, chemical industry, plastics, etc.
Please note that the final cost depends on the customized service you require, the specifications of the raw materials used, the relevant national laws, and the distance of transportation. Take the example of booking a tall container of products:
