  • The use of granite for press roll construction dates back to at least the 1700s and the first granite was probably quarried in Scotland near Aberdeen.
  • The intent of this paper is to familiarize mill personnel with the properties of granite and serve as an aid in troubleshooting granite roll problems.
  • Granite has relatively low tensile strength, but very high compressive strength. To avoid any stress on the granite during roll application, the granite roll is always pre-compressed by a steel central shaft of tension bars.
