| Description | YSZ milling media are available in various shapes and size for any kinds of traditional and most high energy mills. (such as micro mill, ultra micro mill, jar mill, basket mill, ball, sand, pearl, disc and pin mill, planetary, vibratory and attrition ball mill, etc.) to grinding and disperse various materials effectively and economically. | Ceria (cerium dioxide,CeO2)stabilized zirconia (zirconium dioxide ,ZrO2) is also a high-quality grinding medium.CSZ grinding media have highest density(6.2g/cm3) among the different types of ceramic grinding products.Due to this high density, it may be used to mill even high viscosity compounds, in which other media may float. | Zirconium silicate grinding media are popular, medium density (4.0g/cm3) products. Grinding beads are produced from specially formulated zirconium silicate, using a carefully controlled dripping technique followed by high temperature sintering and surface conditioning. Being a sintered bead, it does not have the problems that electro-fused beads have, such as broad size, bad roundness large pores, etc. | Zirconia Toughened Alumina (ZTA) bead was sintered from alumina powder and zirconium silicate powder. Compared to the alumina beads, it has a higher fracture toughness and lower hardness. It is an economic ceramic bead to replace Kaolin bead, silica sand and other natural grinding media. |
