CRUSHING ROLL WITH EDGE PROTECTION

摘要

A grinding assembly (10) for the comminution of material that enhances the durability of the side edges of both a grinding roll (12) and a flange roll (14). Both 5 the grinding roll (12) and the flange roll (14) include a wear ring that is received within a side groove formed at each end of a cylindrical roll body (20). The wear ring includes a series of spaced receiving cavities that each receive a wear member. Each wear member (64) includes a radially outer surface and an axial end face to enhance the durability of the edge of the roll body (20). The edge ring 10 (52) is retained on the roll body by a series of connectors that pass through the edge ring. In the flange roll design, a flange ring (24) is attached to the roll body (2) by a series of connectors that also secure the edge ring to the roll body. *6 sEo
