Product Details
High-Strength Zirconia Ceramic Grinding Disc
• High-Strength Zirconia Ceramic Grinding Disc is a non-magnetic, chemically inert ceramic component developed for sand mills and bead mills used for grinding and dispersing.
• A machining tolerance of 0.005 mm guarantees an accurate fit, while excellent wear and corrosion resistance extends the service life of the equipment by 3-10x compared with metal parts.
• Available in a range of sizes and to customer drawings; batch quantities and tooling can be arranged on request.
