The importance of iron ore crushing process; Before dry selection, the lean iron ore requires millimeter-scale fine crushing by the fine crusher. If the particle size of the iron ore is not small enough in the crushing stage, low-grade iron ore is difficult to be selected later, which will cause serious waste of resources. ...Web

Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions ...Web

Grinding and Crushing. Grinding and crushing of ore is undertaken to physically liberate valuable minerals prior to separation by physical and chemical processes. Crushing is done dry, and is used for coarse size reduction. Grinding is used to achieve finer size reduction. Grinding is conducted wet, and chemicals such as lime, soda ash, sodium ...Web

Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing".
