More Information
Summary:An impact crusher includes a center feed disk. The center feed disk includes a peripheral edge portion, a first face, an opposing, second face, a central bore extending through the first and second faces, and first and second countersunk pockets provided about the central bore in the first and second faces respectively. With this arrangement, a fastener having a shaft portion and a head portion can be inserted through the central bore to secure the center feed disk to a drive mechanism, with the head portion residing in the countersunk pocket. With this arrangement, once the first face portion becomes worn, the center feed disk can be removed, inverted and re-mounted such that the second face portion is exposed.
