The first line of defense is selecting self-cleaning screens designed for iron ore's challenges. Look for panels with tapered, funnel-shaped apertures that are wider at the bottom than the top. This design prevents near-size particles from jamming, allowing vibration to pop them free. The screen surface should be made from a specially formulated, non-stick polyurethane that resists the adhesion of damp fines. For very sticky ores, screens with a slightly crowned or textured surface can help break up material layers and promote movement.
