Alumina Balls

High Density Alumina Balls for the Ceramic Industry

99% – 95% – 92% – 90% – 85% – 75% – 70% Alumina Grinding Media from diameter 60mm to 0.6mm

We supply high density alumina balls specifically developed for grinding applications in the ceramic industry, serving manufacturers of porcelain tiles, sanitaryware, tableware, and technical ceramics. Our alumina grinding media are available in multiple purity grades — 99%, 92%, 90%, and 70% Al₂O₃ — allowing ceramic producers to select the most appropriate solution based on milling intensity, raw material abrasiveness, and cost-performance objectives.

The full size range extends from large 60 mm alumina balls for primary grinding stages down to 20mm micro grinding media for fine milling applications. This wide dimensional availability ensures precise process optimization in continuous ball mills, covering coarse crushing, intermediate milling, and ultra-fine particle size reduction.

99% Alumina Balls – Ultra High Purity and Maximum Density

Our 99% alumina grinding balls represent the highest performance grade within the range. Manufactured with ultra-high alumina content and minimal impurities, these ceramic grinding balls offer exceptional hardness, superior bulk density, and extremely low wear rates. They are particularly suitable for high-quality porcelain tile production, technical ceramics, white sanitaryware, and any application where contamination control is critical.

The high density of 99% alumina balls increases impact force inside the mill, improving grinding efficiency and reducing milling time. At the same time, their very low abrasion loss minimizes iron and silica contamination, preserving body whiteness, glaze purity, and chromatic consistency in ceramic products.

92% Alumina Balls – The Industry Standard for Ceramic Milling

The 92% alumina balls are widely recognized as the standard grinding media for ceramic tile and sanitaryware production. They provide a balanced combination of density, wear resistance, mechanical strength, and economic efficiency. In both wet and dry milling systems, 92% alumina grinding media ensure stable particle size reduction and consistent slurry preparation.

For many ceramic manufacturers, this grade offers the optimal compromise between technical performance and total operating cost. Their long service life reduces media consumption, while their structural integrity ensures reliable operation in high-capacity continuous mills.

90% and 70% Alumina Balls – Cost-Optimized Grinding Solutions

For less abrasive raw materials or cost-sensitive production environments, 90% and 70% alumina balls provide reliable and economical alternatives. These ceramic grinding balls are commonly used in red body tile production, engobe and glaze milling, tableware manufacturing, and secondary grinding stages where extreme wear resistance is not required.

Although their density and wear resistance are lower than higher alumina grades, they remain highly effective in controlled milling conditions and allow manufacturers to optimize grinding costs while maintaining consistent slurry quality.

Complete Size Range from 60 mm to 0.6 mm

Our alumina grinding media are available in diameters ranging from 60 mm down to 0.6 mm, covering the entire grinding spectrum required in ceramic production. Larger diameters are typically employed for primary milling stages where higher impact energy is needed, while smaller sizes are used for fine and ultra-fine grinding to achieve narrow particle size distribution and improved slip homogeneity.

The availability of multiple diameters within each alumina grade allows ceramic producers to design optimized ball charge compositions, improving grinding efficiency, reducing energy consumption, and extending mill lining life.

Technical and Industrial Advantages

Produced through controlled forming and high-temperature sintering processes, our high density alumina balls feature a uniform internal structure, low porosity, high compressive strength, and excellent roundness. These characteristics reduce breakage rates and ensure stable long-term performance inside ball mills.

By improving milling efficiency and minimizing contamination, our alumina grinding media contribute directly to better pressing performance, enhanced firing stability, and superior final product quality in porcelain tiles, sanitaryware, and ceramic tableware.
