Abstract
Improved thickness tolerance, easier assembling and substantial economies are attained by constructing resiliently flexible refiner disks by affixing refining surface ring plates to the disk margins by structural bonding agent, epoxy being preferred. In making the refining disk assembly, the disk may be formed from fiberglass or fiberglass-epoxy composite or stainless steel and the epoxy adhered assembly cured in a curing zone wherein, if the disk is formed from an uncured fiberglass material, the disk may be cured at the same time as the bonding agent.
