摘要: A pulverizer for pulverizing a product has container and at least one working part within the container, which may contain medium. At of (1) an inner liner (2) outer shell (3) medium is formed from composite ceramic material containing aluminum oxide as main component, zirconium in amount 15-40 wt. %. Y 2 O 3 CeO present 0.1-5 mol%. comprise having Vickers hardness (Hv) 1300 kgf/mm or higher, whose 100-600 lower than that said member.
