Technical Information on grinding media, grinding beads and abrasives

High performance ceramic grinding media have unique features and allow advanced system solutions and high efficiency in chemistry and technology/engineering. In addition, they offer an optimal chemical resistance.

Grinding beads made from glass are used, when there are no special requirements during the grinding and dispersion process.

Steel is characterized by an enormous hardness, a high resistance to wear and chemical resistance. The steel balls are used for crushing and coarse grinding as well as mixing and homogenizing of heavy substances.
