Product introduction: 

High purity alumina grinding beads are a widely used functional material with unique application value in multiple fields.

Firstly, in industries such as mining, building materials, and metallurgy, high-purity alumina grinding balls can be used as grinding media for grinding materials, such as ore and cement in equipment such as ball mills and fine mills.

It has high hardness, strong wear resistance, is not easy to break, and does not pollute the grinding material, which greatly improves the grinding efficiency. Traditional grinding methods can no longer meet production needs, and the application of high-purity alumina grinding balls has become an indispensable choice.

Secondly, high-purity alumina grinding beads are also widely used in fields such as electronics, healthcare, and chemical engineering.

In the electronics industry, nanoscale high-purity alumina grinding beads can be used for polishing semiconductor chips. Improving their light transmittance and electronic performance.

In the medical industry, high-purity alumina grinding balls can be used as materials for dental and surgical instruments. As they are non-toxic, odorless, and odorless. And will not have any impact on the human body.

In the chemical industry. High-purity alumina grinding balls can be used as catalysts or carriers for catalytic reactions, adsorption and separation processes.

Product feature and advantages:

  • Firstly, high-purity alumina grinding beads have high hardness and wear resistance.

    Due to its fine manufacturing characteristics, its surface is smoother, its friction coefficient is lower. And it will not fail due to excessive heat generated by friction like some ordinary grinding balls. 

  • In addition, the wear degree of high-purity alumina grinding beads is very small. And they will not pollute the grinding material, which can ensure the purity and quality of the grinding material.

  • High-purity alumina grinding beads have strong chemical stability. Its main component is aluminum oxide, which is a chemically inert substance that does not react with other chemicals. And has no impact on the chemical properties of the grinding material, ensuring that the original properties of the grinding material are preserved.

  • The surface of high-purity alumina grinding beads is very clean and dust-free.

    During the manufacturing process, high-precision grinding machines and advanced drying processes are used to ensure that the surface of the grinding ball is free of dust and impurities.

    This is very important for some industries that require very high product quality, such as pharmaceuticals, food, and other industries.
