In July 2024, the service engineer of GREATWALL MIXERS provided on-site supervision services for agitators of a New Energy project in Guangdong province, China. These agitators are mainly used in producing of iron phosphate, NCM precursors, and lithium carbonate.

      About Iron Phosphate, NCM Precursors, and Lithium Carbonate

     Iron Phosphate (FePO₄): Iron phosphate is a compound commonly used as a cathode material in lithium iron phosphate (LFP) batteries. LFP batteries are widely used in electric vehicles and energy storage systems due to their high safety and long cycle life.

     NCM Precursor: NCM precursors refer to the precursor materials for nickel-cobalt-manganese (NCM) batteries. NCM batteries are a popular type of lithium-ion battery known for their high energy density, making them widely used in electric vehicles. These precursors are intermediate products in the synthesis process of NCM cathode materials, primarily containing nickel, cobalt, and manganese elements.

     Lithium Carbonate (Li₂CO₃): Lithium carbonate is a widely used lithium compound and a key raw material for producing lithium battery cathode materials such as LFP and NCM. It is also an important intermediate for producing other lithium compounds and lithium metal.

     Lithium Carbonate (Li₂CO₃): Project Design Overview

     Lithium Carbonate (Li₂CO₃):For this new energy project, the key equipment is a reactor. Our design team, based on the client's process requirements and material parameters, ultimately adopted a combination of one layer of straight blade paddle impeller, one layer of special frame impeller, and one layer of inclined blade open turbine impeller.

     Lithium Carbonate (Li₂CO₃):This combination fully utilizes the characteristics of each impeller type:

     Lithium Carbonate (Li₂CO₃):Straight Blade Paddle impeller: Generates radial flow, suitable for mixing low-viscosity liquids, including suspensions and solutions.

     Lithium Carbonate (Li₂CO₃):Special Frameimpeller: Features a sturdy structure, ideal for mixing large quantities of materials such as slurries, and beneficial for heat transfer processes.

     Inclined Blade Open Turbine impeller: Produces axial flow, suitable for mixing low-viscosity liquids, promoting vertical exchange and improving mixing efficiency.

     Advantages of the impeller Combination.

     This multi-layered mixing approach ensures comprehensive and thorough mixing of materials. The straight blade paddle impeller creates uniform horizontal circulation within the tank, ensuring even material distribution horizontally. The special frame impeller, with its wide impeller, increases the mixing range, effectively promoting the mixing and heat transfer of high-viscosity or large-volume materials. The inclined blade open turbine impeller, with its unique blade design, generates upward and downward flow, enhancing vertical circulation of liquids, thus improving mixing efficiency and facilitating gas dispersion and chemical reactions.

     Energy Efficiency and Flexibility.

     From an energy consumption and efficiency perspective, this combination demonstrates high efficiency and energy-saving characteristics. The straight blade paddle impeller generates strong radial flow in low-viscosity liquids, while the special frame impeller and inclined blade open turbine impeller enhance the overall mixing degree and vertical flow of materials, respectively. This synergistic effect ensures optimal mixing while reducing the energy input required by a single impeller, achieving energy-saving effects.

     Moreover, this combination of impellers offers high flexibility and adaptability for industrial applications, meeting the needs of various process conditions. For example, the special frame impeller excels in heat transfer and crystallization operations, while the inclined blade open turbine impeller is more suitable for mixing large volumes of low-viscosity liquids. This flexibility allows the mixing equipment to adjust the type and operating parameters of impellers according to different material characteristics and production process requirements, ensuring optimal mixing effects.

     The successful completion of this project in Guangdong underscores Greawall Mixers' commitment to providing high-quality, efficient mixing solutions for the new energy industry. Our advanced mixer designs and on-site service ensure that clients achieve the best possible results in their production processes, contributing to the advancement of sustainable energy solutions.
