Abstract

See full text

A grinding roller for vertical axis crushers is disclosed herein that is produced by foundry casting of a metal matrix. The roller includes a plurality of reinforcing inserts on its periphery, wherein some portions of the peripheral surface of a same insert are located at a distance d1 or d2 from the work surface depending on wear stresses. Accordingly, the roller has at least one zone experiencing high wear stress Z1, with at least one portion of the insert positioned at a distance d1 near the work surface of said roller; and a zone with low wear stress Z2, with a portion of the insert positioned at a distance d2 that is set back relative to the work surface of the roller. In some examples, distance d1 is less than distance d2.
