ROLL ASSEMBLIES INCLUDING SUPERHARD INSERTS, HIGH PRESSURE GRINDER ROLL APPARATUSES USING SAME, AND METHODS OF USE

摘要

Embodiments of the invention are directed to roll assemblies configured to exhibit improved wear resistance of stud elements. Accordingly, the roll assemblies of may improve and/or increase the useful life of high pressure grinding roll apparatuses. In an embodiment, one or more stud elements may include superhard material, which may provide superior wear resistance characteristics and may increase the useful life of the rolls assemblies and high pressure grinding roll apparatuses.
