Abstract
On a vertical shaft impact crusher, a table assembly having a reinforcing ring is disclosed. The vertical shaft impact crusher for crushing aggregate material includes a frame, with the table assembly being mountable to the frame for rotation about a vertical axis. The crusher includes a housing defining an impact surface spaced about an interior of the housing and surrounding the table assembly. The table assembly comprises a top surface, a bottom surface, and a peripheral edge. The top surface includes a central portion defining an aggregate landing surface, with the central portion being adapted to permit outward migration of the aggregate material in response to rotation of the table assembly. A plurality of shoe assemblies are mounted to the top surface adjacent to and spaced along the peripheral edge, with each shoe assembly being adapted to cause the outwardly migrating aggregate material to be thrown against the housing impact surface in response to rotation of the table assembly. The shoe assemblies collectively imparting a downward bending moment to the table assembly in response to rotation of the table assembly. A reinforcing ring is mounted to the table assembly bottom…
