ABSTRACT:
A substantially planar screen for a solid particle separator is formed from one or more layers of mesh. The one or more layers of mesh are formed into a series of ridges separated by channels within the plane of the screen. The wire mesh is bonded to a rigid or semi-rigid panel having a plurality of relatively large openings as compared to those of the mesh to create a plurality of repairable screen cells. The support panel is formed with or bent into a series of alternating ridges and channels to create the ridges and channels in the wire mesh when it is bonded to the panel. The cross-sectional shape of the ridges are generally triangular to maximize exposure of surface area of the screen to a flow of material to be separated. Flat surfaces on the ridges and in the channels facilitate repair of screen cells with solid plugs.
