A grinding roll comprising:

• a roll body having a cylindrical outer surface extending axially between a pair of opposite ends;
• a side groove formed at each end of the roll body, the side groove including a support shoulder recessed from the outer surface of the roll body;
• an edge ring received within each side groove, the edge ring including a plurality of spaced receiving cavities;
• a plurality of wear members each received and retained in at least one of the receiving cavities of the edge ring, wherein the wear members are positioned along the edge ring to define an edge of the grinding roll;
• and
• a flange ring attached to the end ring, the flange ring having an outer edge that extends radially past the outer surface of the roll body.

A grinding assembly for the comminution of material comprising:

• a grinding roll and a flange roll positioned adjacent to each other to define an infeed nip therebetween, wherein both the grinding roll and the flange roll comprise:
• a roll body having a cylindrical outer surface extending axially between a pair of opposite ends;
• a side groove formed at each end of the roll body, the side groove including a support shoulder recessed from the outer surface of the roll body;
• an edge ring received within each side groove, the edge ring including a plurality of spaced receiving cavities;
• and
• a plurality of wear members each received and retained in at least one of the receiving cavities of the edge ring, wherein the wear members are positioned along the edge ring to define an edge of the grinding roll;
• wherein the flange roll further comprises a flange ring attached to the end ring, the flange ring having an outer edge that extends radially past the outer surface of the roll body,
• wherein the flange ring is located axially outward from the edge ring of the grinding roll.
