Iron Ore Crushing can be completed in three or four steps, primary crushing (first step), secondary crushing(second step), tertiary crushing (third step) and, in some iron ore quarries, a quaternary crushing (fourth step). For primary crushing, iron ore jaw crusher are widely used and well received. Impact crusher and cone crusher are often used after a jaw crusher, they are used for further crushing. After crushed by impact crusher and cone crusher, if it is necessary, the crushed materials will be sent to a grinding mill for further grinding. The frequently used iron ore grinding mills are iron ore ball mill, trapezium mill, vertical roller mill, super thin grinding mil and so on.
Iron ore crushing and milling plays a very important role in the whole dressing process, because the finer iron ore is, the easier the separation is, and so the less the production cost is. A good choice of iron ore crushing equipment is necessary. The common iron ore crushers are jaw crusher (for primary crushing), cone crusher or fine jaw crusher (for secondary crushing). Materials in large lumps are reduced by crushers into small particles and then separated by vibrating screen. Large ones return to crushing process, while small ones pass to milling step.
Crushed iron ore is moved by belt conveyor to ball mill for grinding, after which, 36% of iron ore is grinded into 200mesh in size. Double spiral classifier and cylinder screen are used to separate large particles from grinded product.
Wet ball mill is usually used in metal ore processing plant. The selection of ball mill is based on ore size, required output, and required ore grade etc.
