ABSTRACT:
An improved roll for a roller press capable of withstanding very high nip forces in a press nip for interparticle crushing including embedding a plurality of spaced wear-resistant surface members in the pressing surface of the roll which are of a material harder than the material of the roll surface surrounding the inserts and by varying the size and number and material properties of the embedded pieces, the wear of the press roll is matched to the materials to be comminuted to minimize wear and to match the wear profile along the roll with extended pressing use.
