Abstract

See full text

A grinding assembly for the comminution of material that enhances the durability of the side edges of both a grinding roll and a flange roll. Both the grinding roll and the flange roll include a wear ring that is received within a side groove formed at each end of a cylindrical roll body. The wear ring includes a series of spaced receiving cavities that each receive a wear member. Each wear member includes a radially outer surface and an axial end face to enhance the durability of the edge of the roll body. The edge ring 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 is attached to the roll body by a series of connectors that also secure the edge ring to the roll body.
