Description

Technical Parameters

92% alumina ceramic grinding balls are made of bauxite, industrial alumina powder, and high-temperature calcined α-Al₂O₃ as the main raw materials, and are made by batching, grinding, isostatic pressing, and sintering at 1600-1990℃. The alumina content is ≥92%, the Mohs hardness is level 9, the density is ≥3.60g/cm³, and the water absorption rate is ≤0.01%. It has the characteristics of high hardness, high wear resistance, strong acid and alkali resistance, and high temperature resistance. It adopts the double forming process of rolling and isostatic pressing, with a surface roughness of Ra≤0.2μm, and the size specifications cover φ1-12 0mm. It is suitable for equipment such as ball mills and vibration mills. The grinding efficiency of ceramic glaze is 40% higher than that of ordinary ball stones, and the grinding fineness of glass powder can reach D50≤1μm. The grinding pollution rate of chemical catalysts is <0.001%; The global market size is expected to reach US$1.8 billion in 2025, and the industrial clusters in Zibo and Pingxiang, China, account for 65% of the production capacity. Mainstream products have passed ISO9001 quality certification and RoHS environmental protection testing, and are suitable for high-precision grinding needs in emerging fields such as electronic ceramics, refractory materials, and lithium battery positive electrode materials.

Product Advantages

1. High wear resistance

The wear resistance of alumina balls is higher than that of ordinary alumina balls. The balls will not contaminate the grinding materials during work, so they can maintain purity and improve the stability of grinding materials, especially ceramic glazes.

2. High density

The effects of high density, high hardness, and high grinding save grinding time and expand the crushing space. Therefore, the grinding efficiency can be improved.
