Abstract:
A pelletizer feed roller comprises a metal core having a ceramic layer with a rough outer surface bonded to the core. The outer surface of the ceramic layer is sealed with a penetrating sealer containing organic solvent and phenolic resin to prevent moisture contamination of the ceramic layer without adversely affecting the coefficient of friction of the feed roller.
