95 Alumina Grinding Beads
Description
Technical Parameters
Products Description
95 alumina grinding beads are produced using ultra white raw materials, eliminating impurities and pollution from the source. They are particularly suitable for grinding white minerals such as kaolin and calcium carbonate (GCC), maximizing the whiteness and purity of the material. In high-speed grinding equipment, it can withstand strong impacts without breaking or shattering, effectively balancing grinding efficiency and usage costs. Unlike ordinary low purity grinding media, 95 alumina grinding beads are targeted at industrial and mining enterprises that have high requirements for material purity, smoothness, and grinding efficiency. They can operate stably in both dry and wet grinding environments, and will not block the equipment after long-term use, greatly reducing the frequency of grinding medium replacement and equipment maintenance costs.
Product Features
1. Ultra white grinding, low material pollution
Made with ultra white raw materials, the beads have a whiter color and higher purity. During the grinding process, there is no impurity precipitation or color mixing, making it particularly suitable for processing white minerals without affecting the whiteness and quality of the material.
2. Ultra low wear and tear, durable and long-lasting
The dense crystal structure formed by 95 high-purity alumina reduces the wear rate to ≤ 0.10 ‰, much lower than that of ordinary grinding beads. Long term use greatly reduces the frequency of adding and replacing media.
3. Smooth surface and good sphericity
After precision molding and polishing, the surface of the beads is smooth, free of burrs, and has high roundness. They have strong fluidity and uniform force during the grinding process, which not only improves the grinding efficiency but also protects the inner wall of the equipment from damage.
4. High compressive strength
It has super strong impact resistance, and under the strong impact of high-speed rotation and grinding machines, the beads remain intact and will not break, avoiding equipment blockage and material pollution caused by broken beads, and maximizing operational stability.
Application
Industrial mineral grinding: suitable for grinding alumina, kaolin GCC, Non metallic minerals such as silica and zirconium silicate, as well as metallic minerals such as gold, silver, nickel, zinc, and lead ore. They are special grinding media for white minerals.
Coatings and pigment processing: used for ultrafine dispersion of water-based and oil-based coatings, pigments, and dyes, improving material fineness and color brightness, without impurity pollution or color interference.
Chemical and ceramic production: suitable for grinding chemical raw materials, electronic ceramics, and magnetic materials. They have strong chemical stability and will not react with the material to ensure product purity.

FAQ
Q1: Is this grinding bead suitable for wet grinding?
A1: Absolutely suitable. Water absorption rate ≤ 0.02%, will not absorb moisture, crush or contaminate materials in wet grinding environment, suitable for dry and wet grinding.
Q2: Will it affect the whiteness of white minerals during the grinding process?
A2: No. Made from ultra white raw materials, the beads have no impurities or fading, which can protect the whiteness and purity of white minerals.
Q3: What particle sizes are available for selection?
A3: The conventional particle size range is 10mm to 50mm. Non standard particle sizes can be customized according to equipment models and material fineness requirements.
