Methods and apparatuses for screening are provided. Embodiments include a screen 

basket apparatus for screening material, comprising a grid frame having a plurality of openings 

arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to 

cover the respective openings of the grid frame. The screening cartridge assembly includes a 

case and a screen assembly fitted into the case, and may be affixed to a set of transversal member 

of the grid frame. The case may be formed of a single injection molded piece integrally formed 

by injection molding one of a polyurethane or a thermoset polymer. The screening elements 

together form a generally continuous screening surface across the exterior of the grid frame, 

which reduces blinding and is resistant to wear and tear.
