SiLibeads Ceramic beads Type ZY Premium Version: V7/2011 Product Data Sheet First created on: 2011-12-09 Updated on: 2012-02-06 Next inspection on: 2012-12-09 Printed on: 2012-02-06 Data file: PDS en SiLibeads Type ZY Premium Page 1 of 2 Product SiLibeads Ceramic beads Type ZY Premium Material Ceramic beads made of Zirconium Oxide / Yttrium stabilised Application Colour and Paint Industry: Ceramic Industry: Plant Protection: Cosmetics: Pharmaceutics: These SiLibeads Type ZY Premium stand out for an extremely low wear and tear caused by using fine crystalline and pure raw materials in the production process. The exact roundness as well as the smooth and polished surface of the beads contributes to this low wear rate. - grinding and dispersion of coating and paint systems, e.g. car paint, corrosion protection, dip paints, industrial and structural paints, wood varnishes, coil coatings - organic/inorganic pigments, e.g. titanium dioxide, ultra marine, iron oxide, etc. - grinding and dispersion of pigments to dye textiles, plastics and food - grinding and processing of electric ceramics, e.g. barium titanate, piezo-electric ceramics, sensors, condensers - processing of enamel - medical technology, e.g. dentures and hip prosthesis - magnetic ceramic, ferrite - technical ceramic components, e.g. exhaust cultivator in engine technology - dispersion of fungicides, herbicides, insecticides - grinding of pigments and solids for lipsticks, skin and sun protection creams - nano grinding for the production of active substances and supplies substances Advantages - high density – 6.06 kg/l - very high wear and tear resistance, depending on the milling process - approximately 40 times better than zirconium silicate beads and about 70 times better than soda lime glass beads. - 6000 hrs operating time are achievable. - low contamination of the grinding product, therefore useable for high-grade grinding of pigments, dyes, pharmaceutical and cosmetic products. - useable 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. - no radioactivity in comparison to ceramic beads made of zirconium silicate and therefore no contamination of the grinding product and no costly disposal of the beads. - conformity to 1935/2004/EC (Food legislation).
