ABSTRACT:
A screen assembly for a conventional vibratory screening machine includes a series of screens bonded to a rigid rectangular metal frame having rectangular tubular frame members and at least two and no more than ten intermediate frame members. This leaves a series of permeable areas through the screen assembly that are in the range of 2-32% of the overall area of the screen assembly. The screens include an upper fine mesh screen which passes particles below a predetermined size and rejects particles above this size. A second or blinding screen, below the first screen, acts to dislodge particles caught in the mesh of the first screen. A load bearing assembly supports the first and second screens and includes a first support screen coarser than the screens above it, a bonding layer and a second support screen coarser than the first support screen.
