degree of rags, wipes, stringy material, and organic matter. A washer and compactor, either integral to the screen or standalone, must be used with fine screens. If the fine-screening facilities remove solids equal to or less than 3 mm (1/8 in.), then it is a common practice to provide coarse screening before fine screening.

Iron ore crushing and screening. Iron ore is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route or through the electrical arc furnace (EAF) route. The majority of world crude steel is made from the BF-BOF route.
