Description

Product description

In the ultrafine powder processing industry, the stability of the classification system directly affects the particle size and purity of the final product. This is especially true in applications such as lithium battery materials and electronic ceramic powders, where control of metal contamination is extremely stringent. Traditional metal classifying wheels are prone to wear after prolonged operation and may introduce metallic impurities. Therefore, an increasing number of airflow milling machines are adopting ceramic classifying wheels as an alternative.

Ceramic classifying wheels are typically manufactured from a single piece of high-purity alumina or zirconium oxide. Ceramic itself has high hardness and good wear resistance, maintaining a low wear rate even under high-speed airflow impact and powder friction. This is particularly important when processing lithium battery cathode materials, as the material itself requires high purity, and any metallic impurities can affect the final performance.

In actual use, the material enters the classification zone with the airflow, and the high-speed rotation of the classifying wheel creates a centrifugal force field. Finer particles pass through the classifying wheel and enter the collection system, while coarser particles return to the grinding zone for further grinding. This process requires the classifying wheel to maintain dimensional stability over a long period; otherwise, the classification accuracy will gradually decrease. Ceramic materials, due to their low wear, more easily maintain stable classification results.

Compared to metal classifiers, ceramic classifiers offer another advantage: a smoother surface. Powder is less likely to adhere to the wheel surface, reducing material blockage and improving equipment efficiency. For powder processing plants requiring continuous production, this significantly reduces downtime for cleaning.

From a maintenance perspective, while ceramic classifiers have a slightly higher initial cost, their longer lifespan results in lower overall operating costs. Many users have found that replacement cycles are significantly extended and equipment operation is more stable after switching to ceramic classifiers.
Currently, these ceramic classifiers are widely used in classification systems for lithium-ion battery cathode materials, lithium iron phosphate, ternary materials, electronic ceramic powders, and fine chemical powders. The size and structure of the classifier can be customized to match various air jet mills, depending on the equipment model.
