▼ Description of Ceramic Grinding Media

Ceramic Grinding Media is one of the best choice of grinding media materials, it has pearl-like luster and smooth working spherical surface. Compared with traditional grinding media, grinding media made of technical ceramics has the characteristics of high density, high hardness, high toughness, etc., so that it has grinding efficiency and service life unmatched by traditional grinding media. Furthermore, the chemical properties of technical ceramics are stable and can prevent pollution of materials, increase production and reduce production costs. The following is a summary of the features of ceramic grinding beads and balls.


 √ Wear Resistant
 √ High Hardness
 √ Smooth Surface
 √ Good Roundness
 √ Very Long Service Life
 √ High Grinding Efficiency
 √ High Chemical Resistance       
 √ High Density (max. 6.2 g/cm3)
