Product application:
Fine grinding of minerals and ores: They are used to grind minerals and ores into fine powders for use in various applications, such as ceramics, glass, and paint.
Grinding of pigments: They are used to grind pigments into fine powders for use in paints, inks, and cosmetics.
Grinding of pharmaceuticals: They are used to grind pharmaceuticals into fine powders for use in tablets, capsules, and other dosage forms.
Grinding of food: They are used to grind food ingredients into fine powders for use in various food products.
Polishing: They are used to polish surfaces to a high finish.
Different contents of alumina grinding balls
65%-68% alumina balls：
These are the most economical option, with moderate hardness and wear resistance.
Applications: Suitable for grinding softer materials like ceramics, glass, and enamels for medium or coarse particle sizes.
Medium-High Alumina Balls (75% - 80% Al2O3):
Offer a good balance between affordability and performance, with higher hardness and wear resistance than medium alumina balls.
Ideal for grinding a wider range of materials, including minerals, ores, and pigments, for medium or fine particle sizes.
High Alumina Balls (90% or more Al2O3):
The most wear-resistant and hardest among the types, providing excellent grinding efficiency and longevity.
Applications: Best suited for demanding applications involving hard and abrasive materials like silicon carbide, tungsten carbide, and gemstones. Also ideal for fine grinding sensitive materials like pharmaceuticals and food due to minimal abrasion.
Technical indicator of 92% alumina balls for Grinding:
The production process of 92% alumina grinding balls is as below:
Raw materials preparation: Making 1-5μm high purity alumina powder, which needs to be processed by preliminary screening and drying.
Formation: Add the alumina powder to the forming machine, the powder will gradually become a ball by rotation or pressure.
Drying and firing: After the ball forms, needs to be dried, and the ball will gradually be hardened. Then the balls into the kiln to fire, and the surface of the ball is melted to form a solid alumina ball.
Quality inspection & packing.

FAQ
Q: Are alumina grinding balls safe?
A: Yes, they are non-toxic and non-sparking. However, wear proper safety equipment like gloves and eyewear while handling them.
Q: What are the advantages of using alumina grinding balls?
A: Advantages include:
High hardness and wear resistance: They last longer and grind more material before replacement.
Low abrasion: They minimize wear on the material being ground, ideal for sensitive materials.
High impact resistance: They withstand high grinding forces.
Chemical resistance: They resist most chemicals for use in corrosive environments.
Non-metallic: They won't contaminate the material with metal ions.
Q: What are some factors to consider when choosing alumina grinding balls?
A: Consider:
Material being ground: Harder materials require higher alumina content.
Desired particle size: Finer grinding needs higher alumina content.
Budget: Higher alumina content is more expensive.
Grinding conditions: Adjust rotation speed, grinding time, etc., based on your needs.
