<p>A one-piece pulverizing mill roller assembly (10) and method of rebuilding the same. The roller assembly comprises a body (54), an integral hub portion (56) and an integral circumferential outside tread portion (53) which mates with an annular groove (20) in a grinding table (18). The roller assembly is composed of a relatively lower hardness steel which will accept hard surface weld beads to rebuild the circumferential outside tread portion as it wears. The rebuilding can be performed in-place in the pulverizing mill.</p> |
