In October 2024, Greatwall Mixers successfully provided customized agitators for a large-scale cathode material project in Guangdong. A professional after-sales engineering team was dispatched to the project site to oversee installation and commissioning, ensuring that the client's production process runs smoothly. This project mainly produces lithium iron phosphate, ternary precursors, and lithium carbonate, providing high-quality material support for the new energy industry.

     About Lithium Iron Phosphate, Ternary Precursors, and Lithium Carbonate

     Lithium Iron Phosphate (LiFePO4)

     Lithium iron phosphate is a cathode material used in lithium-ion batteries, known for its high thermal stability, safety, and long cycle life. While its energy density is relatively low, it performs well in terms of safety and cost, making it commonly used in electric vehicles and energy storage systems..

     Ternary Precursors (NCM/NCA)

     Ternary precursors refer to compounds composed of nickel (Ni), cobalt (Co), manganese (Mn), or aluminum (Al), widely used as cathode materials in lithium-ion batteries. Their electrochemical performance is superior, offering high energy density and power density, suitable for high-performance electric vehicles and consumer electronics.

     Lithium Carbonate (Li2CO3)

     Lithium carbonate is one of the main compounds of lithium, widely used in the production of lithium batteries. It can be prepared through various chemical processes and is a key raw material for lithium-ion battery electrolytes, affecting the overall performance and safety of the batteries.

     Industry Pain Points

     The production processes for lithium iron phosphate, ternary precursors, and lithium carbonate rely heavily on mixing technology, yet they face several challenges. Firstly, the uniformity of the material mixing directly impacts the capacity and cycle life of the batteries; uneven mixing can lead to unstable battery performance. Secondly, the particle size and shape of the final product significantly affect its performance, requiring appropriate shear during mixing. Temperature control is also crucial; if the heat generated by the reaction is not dissipated, it may lead to overly rapid local reactions, resulting in material degradation and ultimately affecting product quality. Therefore, agitator must have good heat transfer capability. Additionally, the corrosiveness and wear of the medium place higher demands on equipment durability. To address these challenges, users need to select professional and efficient agitator and optimize process control to comprehensively enhance production efficiency and product quality.

     Greatwall Mixers' Selection Advantages

     In response to the special process requirements of the core equipment, the reactor, the engineering team at Greatwall Mixers carefully designed a double-layer, four-slanted narrow blade detachable turbine impeller. This combined mixing system has multiple design advantages, enabling efficient mixing that meets the customer¡¯s high dispersion and shear requirements. The double-layer structure provides an upper and lower synergistic mixing mechanism, promoting uniform mixing and dispersion of materials through multi-dimensional fluid shear, significantly improving mass transfer performance and enabling faster and more complete chemical reactions. Furthermore, the detachable design of the impeller facilitates cleaning, maintenance, and adjustments, effectively reducing downtime and ensuring continuous high-efficiency production.
