Features————————
High Hardness:
Alumina beads are characterized by high hardness, providing
excellent wear resistance during grinding processes. This feature
ensures prolonged bead lifespan and consistent performance.
Chemical Inertness:
Alumina is chemically inert and does not react with most chemicals.
This makes alumina grinding beads suitable for applications where
sample purity is critical, as they prevent contamination of the
material being ground.
High Density:
Alumina beads have high density, enabling them to generate
significant impact and shear forces during grinding. This
contributes to efficient particle size reduction and dispersion in
various milling applications.
Matching Machine——————
