Why Snap-Back Decides What Passes Through

Every time a deck cycles, the panel surface deforms under the load and rebounds as the stroke reverses, and that rebound is what keeps apertures from blinding. A rubber screen with healthy recovery sheds the wedged particle on the return stroke, so the open area you specified at purchase is roughly the open area you still have in month ten. When recovery fades, particles that should have been ejected stay put, pegging begins, and the effective open area drops long before anyone notices a visible tear. The result is not a dramatic failure but a slow bleed of capacity, with more oversize reporting to the undersize stream and more recirculating load going back through the crusher.
