Technological cycle of iron ore crushing and grinding under production conditions is possible only in terms of mechanical load being rather labour-consuming and energy-intensive. Application of physical impact methods on iron ore to intensify its crushing and grinding processes is still at the stage of research and development [9].
Iron ore is one of the most important minerals in the world, serving as the primary raw material for steel production. As demand for steel continues to grow globally, efficient and reliable processes for extracting iron from its ore become crucial. Two critical pieces of equipment used in this process are the ball mill and the crusher.These machines play vital roles in the …

A. Jankovic, in Iron Ore, 2015. 8.2 Iron ore crushing and screening. Iron ore is the raw material used to make pig iron, which 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 electric arc furnace (EAF) route.
