Abstract:
Methods and apparatuses for screening are provided. Embodiments include a screen basket (1) apparatus for screening material, comprising a grid frame (1510) having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies (1610) affixed to the grid frame (1510) to cover the respective openings of the grid frame (1510). The screening cartridge assembly (1610) includes a case (1630) and a screen assembly (2000) fitted into the case (1630), and may be affixed to a set of transversal members (1512) of the grid frame (1510). The case (1630) 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 (1510), which reduces blinding and is resistant to wear and tear.
