99.99% alumina oxide ceramic bead manufacturing technique

The production process of alumina grinding ball plays an important role in the field of materials science and ceramic manufacturing, and its fine manufacturing process ensures high hardness, high wear resistance and excellent chemical stability of the product. After completing the preliminary stage of raw material preparation and matching, the production process enters the key molding link.

The process uses static pressing technology to evenly press the finely prepared alumina powder under high pressure, which not only ensures the shape and size of the grinding ball, but also effectively improves the density and mechanical strength of the product. After forming, the grinding ball needs to undergo strict demould and preliminary drying treatment to avoid cracks or deformation due to the influence of moisture in the subsequent process.

This is followed by the high temperature sintering step, which is the key to determining the performance of the grinding ball. In the high temperature furnace, the grinding ball undergoes a series of physical and chemical reactions, forming a strong crystal bond between the alumina particles, further enhancing its hardness and wear resistance. The precise control of sintering temperature and time is very important, and a slight deviation may affect the final quality of the grinding ball.

Finally, after fine grinding and polishing treatment, remove surface defects, ensure that the surface of the grinding ball is smooth like a mirror, reduce friction resistance during use, and improve grinding efficiency. In addition, each batch of grinding balls are subject to strict quality testing, including hardness testing, wear resistance testing and chemical stability analysis, to ensure that each grinding ball can meet the established performance indicators and meet the diverse needs of customers. At this point, the production process of alumina grinding ball has been successfully concluded, and the product is widely used in various grinding, dispersion and mixing processes with its excellent performance.
