Grinding roll

Abstract

The present disclosure relates to a grinding roll comprising a roll body having a cylindrical outer surface extending axially between a pair of opposite ends, and a side groove formed at each end of the roll body, the side groove including a support shoulder recessed from the cylindrical outer surface and / or from surfaces of the opposite ends of the roll body. The grinding roll further comprises an edge ring including a plurality of spaced receiving cavities, and a plurality of wear members, each wear member being received and retained in at least one of the receiving cavities of the edge ring. The wear members are positioned along the edge ring to define an edge of the grinding roll, and the edge ring is received within each side groove. The plurality of wear members is arranged to provide a wear protecting surface which is angled in relation to the cylindrical outer surface of the roll body. Providing an angled wear protecting surface prevents excessive build-up of material on the grinding roll and reduces the need for maintenance. A grinding assembly and an edge ring segment providing improved wear protection are also disclosed.
