Static screening system and methods

Abstract

Static screening apparatuses that provide improved efficiency in the removal of undersized particles from oversized particles. In an embodiment, a static screening apparatus incorporates two or more (e.g., multiple) stacked screening modules allowing for adding additional screening capacity without significantly increasing space requirements for the multiple screening apparatuses. In some embodiments, a static screening apparatus utilizes specialized synthetic screening surfaces having an increased open area in relation to convention wire and wedge wire screens. The increased open area of such synthetic screen surfaces provides more efficient separation of oversized materials from undersized materials in sieve or static screen assemblies. In further embodiments, a stacked static screening apparatus may incorporate synthetic screening surfaces.
