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.

The crushing process is by the run-of-mine, whereas the ground, i.e. the second step after crushing, is on dry material. Heavy forces such as compression, impact (mainly for crushing) and attrition (mainly for grinding) are responsible for crushing or grinding. Crushing and drying are slightly different, as crushing involves a drying process.
