High-end alumina, with its exceptional resistance to high temperatures, superior strength, excellent insulation properties, and remarkable chemical stability, has become an indispensable key foundational material in strategic emerging fields such as aerospace, information electronics, new energy, and precision ceramics. From high-temperature component coatings in aircraft engines to insulating substrates used in chip manufacturing, and even to the separator support materials in next-generation electric vehicle batteries, the performance of high-end alumina directly determines the quality and competitiveness of end products.

High-end alumina is not a single category, but rather a series of products developed based on indicators such as purity, particle size, and morphology. 。 The vertical grinding machine achieves precise customization of material properties through multi-stage collaborative control in high-end alumina processing. 。

The grinding chamber of the vertical grinder utilizes The “vertical circulation” structure utilizes grinding media—typically high-purity zirconia beads, which prevent impurities from being introduced due to media wear—driven by a high-speed rotating agitator to create a multi-dimensional force field comprising “shear force + impact force + grinding force.” Compared to traditional ball mills, its key advantages are:

Particle size control is more precise: By adjusting the stirrer speed, optimizing the grinding media fill level, and regulating the slurry circulation flow rate, alumina particle size can be accurately controlled to within Required Interval, and particle size distribution width Narrow 。

Morphology control is more flexible: For the diverse application scenarios requiring specific alumina morphologies, the vertical grinding machine can achieve this by adjusting process parameters. “Customization”: For spherical alumina required (e.g., for lithium-battery separator coatings), reduce the stirring speed and increase the media filling rate, employing “gentle grinding” to minimize particle sharp edges. For flaky alumina needed (e.g., for thermally conductive interface materials), increase the rotation speed while decreasing the media filling rate, leveraging high shear forces to achieve particle “flattening.”

The vertical grinder is equipped with The PLC control system enables full-process automation—from raw material pre-processing and grinding parameter adjustment to post-processing. Reduce manual labor Operation can keep the batch-to-batch variation rate of product performance within Below 3%, it is crucial for highly consistency-demanding fields such as electronics and aerospace.
