High Alumina Ceramic Grinding Medium Beads for Wet Grinding Line

Producrt Introduction
Wear-resistant alumina ceramic grinding medium bead is a common grinding medium, which is made of high-purity alumina and other ceramic materials. In addition, it also has the advantages of good corrosion resistance, high specific gravity, cost-effective and wear resistance, and can be widely used in areas with high quality requirements.It has extremely high wear resistance and hardness, enabling efficient grinding of a wide range of powders, ores or chemical materials in high-speed ball mills. Common specifications are φ0.5mm~φ20mm, and grinding medium beads of different specifications and colors can also be customized according to customer needs. The use of these media balls increases grinding efficiency, reduces energy consumption and material loss, and meets the requirements of grinding processes and product quality.

Feature
1. High hardness: The hardness of high alumina ceramic grinding medium bead is very high, generally reaching about 9 Mohs, which can effectively resist wear during the grinding process and maintain a long service life.

2. Strong corrosion resistance: Alumina has good corrosion resistance to most acid and alkali media at room temperature, so high alumina ceramic grinding beads also have excellent corrosion resistance and can be used to process various acid and alkali media or drugs.

3. Strong thermal stability: High alumina ceramic grinding medium bead have high thermal stability, can maintain stable performance at high temperature, and will not be deformed or melted.

4. Strong pressure resistance:High alumina ceramic grinding medium beads have high pressure resistance and can withstand higher pressure without cracking or deformation.

5. Uniform particle size: The particle size distribution of alumina ceramic grinding beads is relatively uniform, which is more stable for the grinding effect and will not have a bad grinding effect.
