摘要： A disclosed screening apparatus (10) includes a subgrid, and a screen element (81100) attached to the subgrid (8200) via laser welding at a plurality of attachment positions such that, under vibrational excitation, the screen element has a pre-determined profile of vibrational motion relative to the subgrid. The screen element may be attached at a maximal number of attachment locations to the subgrid to minimize relative motion of the screen element and the subgrid under vibrational excitation, or the screen element may be attached a sub-set of the maximal number of attachment locations to allow vibrational motion of the screen element relative to the subgrid. A disclosed method may include attaching a plurality of screen elements to a respective plurality of subgrids, attaching the plurality of subgrids to one another to form a screening pre-assembly, and cutting edges of the screening pre-assembly to form the screen assembly having a perimeter with a pre-determined shape.

摘要： Flow divider (10) that includes a slurry receiving compartment (40) and a discharge arrangement having a plurality of discharge apertures (46). The slurry receiving compartment (40) is arranged to relatively uniformly flow a portion of a slurry into each of the discharge apertures (46). The discharge apertures (46) may be arranged linearly and/or horizontally such that the portions of the slurry exits each of the discharge apertures (46) at a relatively even flow rate and feed feed boxes connected to vertically tiered screening surfaces of a screening machine (100).

摘要： Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame (1510) having a plurality of openings (1513) arranged in a lattice and a plurality of screening cartridge assemblies (1610a,1610b, 1610c) affixed to the grid frame (1510) to cover the respective openings (1513) of the grid frame (1510). The screening cartridge assembly (1610a, 1610b, 1610c) includes a case (1630a) and a screen assembly (1640a, 1640b) fitted into the case (1630a), and may be affixed to a set of transversal member (1512) of the grid frame (1510). The case (1630a) may be an injection molded thermoplastic polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across an exterior portion of the grid frame (1510).
