摘要： A screen assembly is formed by attaching side edges of a plurality of screen elements to each other. Reinforcing fibers may be embedded in the material of selected screen elements. The reinforcing fibers extend in a direction in which the screen assembly will be tensioned to secure the screen assembly to a screening machine. Hook strips may be attached to ends or sides of the screen assembly to facilitate mounting the screen assembly to a screening machine.

摘要： Disclosed embodiments include a screen deck assembly that can be mounted on a vibratory screening machine. The screen deck assembly includes a plurality of elongated support members that extend in a first direction. A plurality of support rods are mounted to the elongated support members. The support members and support rods form a screen support surface. The support rods extend in a direction that is transverse to the support members.

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.
