A magnetically retained screen assembly for a conveyor for processing goods is disclosed. The magnetically retained screen assembly includes one or more magnetic screens and one or more magnet assemblies, wherein the one or more magnet assemblies are configured to magnetically retain the one or more magnetic screens within the conveyor support structure.

Apparatus, systems, and methods for providing a screening surface in a vibratory machine are provided. In one example embodiment, a screening system includes a plurality of bucker bar covers. Each bucker bar cover is adapted to fit over one of a plurality of bucker bars. Each bucker bar cover can have one or more recesses. The system further includes a plurality of panel fastening members (e.g., panel fastening straps, panel fastening shrouds, etc.). Each panel fastening member is adapted to extend across the plurality of bucker bar covers in one of the one or more recesses of the bucker bar covers. Each panel fastening member can have a fastening feature. The system can further include a plurality of screen panels. Each screen panel can have a fastening recess having a shape adapted to engage with the fastening feature of one of the panel fastening members.

A system and a method tension a screen having a generally rectangular shape defined by a length and a width. The screen has a profile with a shape extending the length of the screen. A rod has a channel configured to receive the shape of the profile of the screen therein. The rod has a plurality of segmented portions such that a first segmented portion of the plurality of segmented portions is separable from a second segmented portion of the plurality of segmented portions. The screen is positioned on a frame. The rod is positioned parallel to the length of the frame on two sides. A clamping mechanism tensions the screen with respect to the frame.

A system includes a first screen having a first latch on a first end of the first screen, a second screen having a first catch on a first end of the second screen, and a screen adapter that connects the first screen and the second screen. The screen adapter includes an elongate body, a first catch formed on a first side of the elongate body that engages the first latch on the first end of the first screen, and a first latch formed on a second side of the elongate body that engages the first catch on the first end of the second screen. A method includes inserting a first screen into a vibratory separator, inserting a screen adapter into the vibratory separator, coupling the screen adapter to the first screen, inserting a second screen into the vibratory separator, and coupling the second screen to the screen adapter.
