High strength,Excellent wear resistance,20 times more than commonly ceramic ball of France or ceramic ball,keep the material high degree of purity.
High density,high grinding efficiency,shorten 50% gridning times.
Very good roundness,very smooth and shiny surface,long times of use.
Ø0.5-3mm Grinding ball use in sand mill
Ø5-20mm Grinding ball use in mix mill and ball mill
OverØ20mm Grinding ball use in ball mill
