Mining Screens Multotec
Multotec Screens reduce pegging and blinding: Blinding occurs when any particles such as: dirt, minerals and other substances, stick to and bridge across your screening surface apertures. This creates a stubborn paste that blocks screening material from movement through. Pegging is the occurrence of irregular material blocked in the screen apertures,

Iron ore beneficiation: an overview - ScienceDirect
Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce 100% fine product.
