Abstract: A clip rail comprises an elongated body having a first end and a second end. The elongated body defines an upper recess configured to engage with one or more screen panels, the elongated body further defines a lower recess configured to engage a support member of a screening apparatus. Each of the first end and second end includes a two-platform structure, the two-platform structure configured to engage with another two-platform structure, wherein the first platform is offset from the second platform. Further, the first platform is adjacent to the second platform, and the second platform is laterally and vertically offset from the first platform, and the first platform is in a first plane and the second platform is in a second plane.

Abstract: A horizontal centrifugal scroll screen apparatus including: a housing; a frusto-conical screen assembly mounted within the housing and having an outer inlet end and an inner discharge end, the screen assembly being mounted for driven rotation via a base-of-spoke piece disposed across the inner discharge end thereof; and a frusto-conical scroll assembly coaxially mounted for differential driven rotation within the screen assembly and including an outer closed end in the proximity of the outer inlet end of the screen assembly and being adapted to direct material to be screened from a material supply conduit to the outer inlet end of the screen assembly for screening and conveyance to an outlet provided in the base-of-spoke piece.
