  • Non-compressive loading of a screen basket for a pulp pressure screening apparatus
    Patent number: 5326470
    Abstract: A screen basket with greater structural integrity and fatigue resistance is mounted within a screening apparatus with substantially no axial compressive loading. The screen basket has end portions attached to a pair of support members with screen basket position engagement elements or fasteners to place the screen basket in a condition with no substantial axial compressive load. The screen basket, supported in this way, remains stationary when exposed to high hydrodynamic torsional forces and reduces the magnitude of deflections and bending stresses placed on the screen basket. The screen basket is preferably mounted in axial tension or with an axial neutral load.
