摘要： Screening media is arranged to screen oversized material, the media having a main body and a plurality of openings extending through the main body between an upward facing contact face and a downward facing bottom face. A textured pattern is provided at the contact face to provide a roughened surface for the partial entrapment of material fines. Such a configuration protects the screen media from aggressive contact with the material to be screened and provides a bedding layer that is maintained by material-on-material attrition during bulk material flow over the media.
