As an upgraded material for lithium iron phosphate, lithium manganese iron phosphate, with the stability of its olivine structure, maintains high safety while increasing the voltage platform by 0.7V and energy density by approximately 20%. Its cost per watt-hour is lower than ternary materials, making it a potential star in the power battery field. However, its industrialization faces multiple challenges: uneven particle size distribution leads to poor consistency, low electronic conductivity leads to insufficient rate performance, and high-temperature and high-pressure processes place stringent demands on equipment. The technological innovation of vertical grinding mills provides key support for its large-scale production.

In response to the requirements of nanometer-scale fineness (tens of nanometers) and high consistency for lithium manganese iron phosphate materials, the vertical grinding mill adopts a vertical structure design. The materials form an up-and-down convection in the grinding chamber. The high-speed rotating stirring mill drives the grinding media balls to generate eddy current motion, achieving shearing, dispersion, and rubbing to obtain nanometer-scale powder particles.

The vertical grinding mill adopts a screen-less design, eliminating the risks of blockage and bead leakage. Coupled with a ceramic grinding chamber (such as silicon carbide lining), it avoids metal contamination and ensures material purity. This characteristic perfectly matches the sensitivity of lithium manganese iron phosphate to impurities and meets the stringent standards of green production of new energy materials. The vertical grinding mill is also equipped with a permanent magnet direct drive motor, achieving a comprehensive energy saving rate of 20%-30%. The intelligent control system supports formula management and real-time monitoring of process parameters, ensuring the stability of each batch.
By controlling the ratio of grinding media and the speed, the vertical equipment can precisely control the particle size of lithium manganese iron phosphate (e.g., the particle size of the second-generation Fuli product is reduced to the nanometer level), improving the uniformity of particle distribution and increasing the material compaction density (up to 2.0g/cm³) and rate performance. It ensures that the finished product fineness meets the standard, while reducing the introduction of iron impurities and improving the purity of the material, promoting the industrialization process
