Screen basket

A screen basket comprising:

• a plurality of profiled bars generally aligned along a longitudinal axis so as to define a slotted cylindrical wall having an inner side and an outer side extending between two longitudinal ends;
• each of the profiled bars having a radial profiled portion and a radial locking portion;
• and
• at least one support ring, each support ring mounted to at least some of the plurality of profiled bars substantially transversally therefrom, for assembling the plurality of profiled bars into the slotted cylindrical wall;
• each support ring including a plurality of grooves therein;
• each groove being configured and sized for complementary receipt of the radial locking portion of a respective one of the profiled bars;
• each screen basket further comprising a moveable insert adjacent the support ring and the radial locking portion of the profiled bars, the moveable insert comprising a disk having an aperture therein, said screen basket further comprising a camming actuator adapted for insertion into said aperture to provide a radially directed camming action on said disk to move said disk radially toward the locking portion of the profiled bars thereby providing a locking force to bias the locking portions of the profiled bars toward the grooves, wherein said camming actuator comprises an oval rod, said disk aperture having a flat edge portion whereby rotation of said rod in said aperture will provide said camming action.
