Middle Alumina Grinding Balls

1.The balls have good wear-resistance and lower generates costs.

2.The price/performance ratio is good.

3.The balls have excellent grinding efficiency.

4. Smooth surface, good sphericity.


Middle alumina grinding balls (SXAL Series) are a type of ceramic grinding media that are commonly used in industrial applications. They are typically composed of 70-80% aluminum oxide and are produced using advanced ceramic manufacturing techniques. Middle alumina grinding balls are known for their high wear resistance, chemical stability, and low contamination levels. They are often used in applications where high-performance grinding media is required but where the use of high-purity materials like high purity alumina beads is not necessary. Some common applications of middle alumina grinding balls include ceramic, paint, and pigment grinding, as well as mining and mineral processing.

SXAL middle alumina grinding ball, produced from high grade bauxite and alumina raw material, exhibit high wear resistance with fine crystal structure. It have excellent grinding efficient and significant cost which cut down the power consumption, labor and facility cost. SXAL series grinding ball have longer service life 20-40times than command ceramic ball and nature stone ball. The composite cost is only 40-60% nature stone ball. It's mainly used in grinding body and glaze of  ceramic tile, sanitary ware and ceramic table ware etc.
