The particle size distribution, morphology, and purity of the positive and negative active materials and conductive agent fillers directly determine the energy density, rate performance, and cycle life of the battery.

The vertical mill adopts a unique vertical structure design. The grinding media (such as ceramic beads) move at high speed under the action of strong centrifugal force, and the materials form a strong vortex in the grinding chamber. This dynamic environment causes high-frequency collisions and shearing between particles and between particles and media, significantly improving the pulverization efficiency, especially excelling at efficiently processing raw materials to the micron or even submicron level. 。

The core grinding components (liner, media) of the vertical mill can be comprehensively made of high-hardness, high-wear-resistant non-metallic materials (such as ceramics, polymer composites, etc.), eliminating the risk of introducing metal foreign objects such as iron, nickel, and chromium from the source. At the same time, the optimized sealing design and smooth internal flow field greatly reduce the possibility of material residue and cross-contamination.

The process parameters of the vertical mill (such as media filling rate, speed, classification wheel frequency, feed rate, solid content, etc.) are flexible and can be finely customized for pulverization of lithium battery raw materials with different hardnesses and target particle sizes (such as lithium cobaltate, lithium iron phosphate, ternary materials, graphite, silicon carbon anode, conductive carbon black, etc.). Whether it is a single material with an extremely narrow particle size distribution or a composite slurry precursor that needs to be uniformly dispersed, it can provide a reliable and stable solution. Its modular design also reserves space for future capacity upgrades and technological iterations. and The vertical mill has a large single-machine processing capacity. 、 It has a small footprint, not only effectively improving production efficiency, but also reducing the overall production cost.
