摘要： An example nonlimiting embodiment of the present invention provides a flow divider that includes a slurry receiving compartment and a discharge arrangement having a plurality of discharge apertures. The slurry receiving compartment is arranged to relatively uniformly flow a portion of a slurry into each of the discharge apertures. The discharge apertures may be arranged linearly and/or horizontally such that the portions of the slurry exits each of the discharge apertures at a relatively even flow rate and feed feed boxes connected to vertically tiered screening surfaces of a screening machine.

摘要： A disclosed screening apparatus includes a subgrid, and a screen element attached to the subgrid 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.
