Technical Information
High performance grinding beads from ceramics with its unique characteristics allow advanced system solution and high efficiency in chemistry and technics. Moreover they have an optimum chemical resistence.
Glass grinding beads are used when no special demands for grinding and dispersing need to be met.
Steel is known for its extreme hardness, high wear resistance and chemical constancy. The balls are used for hard crushing and rough grinding, but also for mixing heavy materials.
... are produced from yttrium stabilized, ultrapure zirconia powder. They have a high density and an extreme hardness, so product polution can be prevented.
- Recommended for:
- magnetic, piezo electric and dielectric materials
- high purity advanced ceramic materials
- pigments,
- pharmaceuticals
- cosmetics
- food stuff
- coating materials
... are produced from a special zirconia powder, enriched with yttrium. So a high grinding efficiency and also a special wear resisitance in high performance mills with high energy input is guaranteed.
- Recommended for:
- electronic ceramics
- pigments, minerals
- cosmetics
- paints, dyes, inks
