0.2-3.5mm Alumina Ceramic Grinding Balls Zirconia Grinding Beads
0.2-3.5mm Zirconia Ceramic Beads /Ball Used As Grinding Media
Product Introduction
Zirconia used in calcium carbonate, kaolin, zircon sand, pigments, dyes, graphite, coatings, metal mining industries used as grinding and dispersion media. The beads can also be used for shoot peening polishing and other metal surface treatment. According to the customer's different grinding equipment, we can match different density grinding beads.
Properties
Good roundness, high sphericity, the surface has excellent gloss. the product is compact in sintering and has no defects such as porosity and so on.
Excellent toughness, higher crushing strength than ordinary alumina beads, non-fragmentation in long-term high speed operation.
Good stability, acid and alkali resistance.
Low equipment attrition.
