ABSTRACT:
An improved, abrasion-resistant rice hulling roll comprises a core with coating of a nitrile rubber compound, particularly a carboxylated nitrile rubber compound. The hulling rolls of this invention are characterized by substantially improved wear life as compared to conventional rolls made of styrene-butadiene rubber (SBR). The nitrile rubbers are also useful in other wear-resistant applications.
