Abstract
A screen panel for a vibratory machine is disclosed. The screen panel can include a reinforcing structure having a top surface. The reinforcing structure can define a plurality of apertures through the reinforcing structure. A polymer layer can have a bottom surface that is arranged over the top surface of the reinforcing structure. The polymer layer can define a plurality of apertures therethrough. Each aperture of the plurality of apertures of the polymer layer can be aligned with a single respective aperture of the plurality of apertures of the reinforcing structure.
Claims19
A screening system for a vibratory machine, the screening system comprising:
- a first screen panel comprising a plurality of bridge elements that defines a plurality of apertures therethrough in a vertical direction, the first screen panel having a plurality of edges, and wherein the first screen panel has a plurality of partial bridge elements extending away from the first screen panel from at least one edge of the plurality of edges of the first screen panel in a lateral direction perpendicular to the vertical direction, wherein the first screen panel is modular and removable from the screening system;
- and
- a second screen panel comprising a plurality of bridge elements that defines a plurality of apertures therethrough in the vertical direction, the second screen panel having a plurality of edges, and wherein the second screen panel has a plurality of partial bridge elements extending away from the second screen from at least one edge of the plurality of edges in the lateral direction, each of the plurality of partial bridge elements of the second screen panel being aligned with respective ones of the plurality of partial bridge elements of the first screen panel to form at least one aperture in the vertical direction at an intersection of the first screen panel and the second screen panel, wherein the second screen panel is modular and removable from the screening system independently of the first screen panel.
A modular and removable screen panel for a vibratory machine, the screen panel comprising:
- a reinforcing structure, the reinforcing structure comprising a first plurality of bridge elements having respective top surfaces and a second plurality of bridge elements having respective top surfaces, the second plurality of bridge elements intersecting the first plurality of bridge elements to define a plurality of apertures;
- a polymer layer defining a plurality of apertures therethrough, and wherein the polymer layer is arranged over the reinforcing structure such that the polymer layer covers all respective top surfaces of the first plurality of bridge elements and covers all respective top surfaces of the second plurality of bridge elements;
- and
- a plurality of partial bridge elements extending away from a perimeter of the screen panel defined at least partially by the first plurality of bridge elements or the second plurality of bridge elements.
A screening system for a vibratory machine, the screening system comprising:
- a first screen panel comprising a plurality of first bridge elements that defines a plurality of first apertures therethrough in a vertical direction, a first perimeter of the first screen panel being defined by at least a portion of the first plurality of bridge elements, wherein the first screen panel is modular and removable from the screening system;
- a plurality of first partial bridge elements extending away from the first perimeter of the first screen panel;
- a second screen panel comprising a plurality of second bridge elements that defines a plurality of second apertures therethrough in the vertical direction, a second perimeter of the second screen panel being defined by at least a portion of the second plurality of bridge elements, wherein the second screen panel is modular and removable from the screening system independently of the first screen panel;
- and
- a plurality of second partial bridge elements extending away from the second perimeter of the second screen panel, wherein the plurality of first partial bridge elements and the plurality of second partial bridge elements meet along an intersection line and define a plurality of intersection apertures when installed in the screening system.
