ABSTRACT:
The invention relates to a bimetallic casting serving as a wear piece in vertical mills and its method of manufacture. It includes a core (13) made of a ductile cast iron and provided with mechanical bonding elements in the form of pins (15) which are rendered integral with an outer casing (17) by casting, the outer casing being made of a non-ductile wear material having a high chromium content. Such castings are used for being mounted on the hub of a roller of a so-called vertical-axis crushing mill.
