Product details

Alumina ceramic balls, also known as Al₂O₃ balls, are a type of high-performance ceramic grinding media widely used in various industrial applications. Manufactured from refined alumina oxide powder with purity levels of 92%, 95%, or even 99%, these ceramic balls deliver superior hardness, high thermal stability, and excellent wear resistance. Their spherical shape and consistent density make them ideal for use in ball mills, sand mills, and other milling systems where high grinding efficiency and minimal contamination are critical.

Available Grades:

70%-85% Al₂O₃

92% Al₂O₃

95% Al₂O₃

99% Al₂O₃ (for ultra-high purity requirements)

Size Range:

0.5 mm to 60 mm (custom sizes available upon request)

Features & Benefits:

High Hardness and Strength:

Alumina ceramic balls exhibit excellent mechanical strength and Mohs hardness above 9, making them highly durable and suitable for tough milling environments.

Superior Wear Resistance:

Their high density and hardness reduce abrasion and media loss, ensuring longer service life compared to conventional grinding media such as steel or natural stones.

Chemical Inertness:

These ceramic balls are chemically stable in acidic and alkaline environments, making them suitable for chemical processing and formulations where contamination must be avoided.

High Thermal Stability:

Alumina ceramic balls can withstand high processing temperatures, up to 1500°C, without degradation, deformation, or performance loss.

Low Porosity and High Density:

Their low water absorption rate (<0.01%) and high bulk density (up to 3.6 g/cm³ for 99% alumina) ensure excellent grinding efficiency and consistent milling performance.

Excellent Corrosion Resistance:

Ideal for use in corrosive environments, particularly in the chemical, mining, and metallurgical industries.

Eco-Friendly and Recyclable:

Non-toxic and recyclable, alumina ceramic balls are safe for the environment and reduce the frequency of media replacement.

Applications:

1.Grinding Media in Ball Mills and Sand Mills:

Extensively used in mineral processing, cement manufacturing, ceramic glaze preparation, and paint production for fine powder grinding and particle size reduction.

2.Mining and Metallurgy:

Effective for grinding ores and abrasive minerals, especially in applications requiring low contamination and long-lasting performance.

3.Chemical and Pharmaceutical Industries:

Used in the processing of chemicals, dyes, and pharmaceutical powders, where purity and product integrity are essential.

4.Refractories and Insulation:

Alumina balls are used in high-temperature kiln linings, heat-resistant insulation materials, and thermal storage systems.

5.Petrochemical and Catalyst Carriers:

Employed as catalyst bed support media in refining and petrochemical processes due to their high strength and thermal shock resistance.

6.Industry Compliance:

Alumina ceramic balls conform to international quality standards, such as ISO 9001 and ASTM specifications. They are engineered to meet the rigorous demands of industries that require grinding media with high reliability, durability, and performance consistency.
