Colour and Paint Industry: Grinding and dispersion of coating and paint systems, e.g. car paint, corrosion protection, dip paints, industrial and structural paints, wood varnishes, coil coatings.
Ceramic Industry: Grinding and processing of electrical ceramics, e.g. barium titanate, piezo-electric ceramics, sensors, condensers.
Plant Protection: Dispersion of fungicides, herbicides, insecticides.
Cosmetics: Grinding of pigments and solids for lipstick, skin and sun protection creams.
Pharmaceutics: Nano grinding for the production of active substances and supplies substances.
Battery raw materials: Ultra fine grinding and dispersion of battery raw materials for Cathode- and Anode materials, for example Lithium-Ion-Batteries.
High density – 6.00kg/l
High wear and tear resistance, depending on the milling process – approximately 20 times better than zirconium silicate beads and about 35 times better than soda lime glass beads.
High operating time is achievable
Low contamination of the milling product, therefor usable for high-grade grinding of pigments, dyes, pharmaceutical and cosmetic prducts.
Usable for all modern types of mills and high energy mills (vertical and horizontal).
Excellent crystal structure avoids bead breakage and reduces the abrasion of mill parts.
Resistance to a lot of corrosive liquids. Smooth surface, easy cleaning because of low porousness.
