Abstract:
1. A modular vibratory screening machine having a basket formed and arranged for mounting one or more processing modules, or a basket constructed from one or more processing modules, said modular vibratory screening machine comprising: a) a processing module having an apparatus including a conduit, that includes a screening portion and formed and arranged to divide a liquid and solids mixture feed flowing through the conduit into a first, cleaned stream having liquid and solid particles of below a selected size limit, and a second, concentrated, stream having liquid, and solid particles above the selected size limit; wherein an outlet for the second concentrated stream from the screening portion is in the form of a weir assembly; the weir assembly comprising: said modular vibratory screening machine optionally having one or more the following modules: b) a top screen or scalping deck; c) a conventional single deck screening module; d) a dual deck screen module; e) a dual deck screen module with a flow distribution system allowing parallel or series processing on the two screens; f) a dual deck screen module with a flow distribution system switchable between allowing parallel or series processing on the two screens; g) a multiple deck screen module having three or more screens in a stack; h) a multiple deck screen module having three or more screens in a stack with flow distribution system; and i) a flow distribution module for fluid interconnection between screen decks and/or between modules.
