Iron ore refers to the ore containing iron or iron compound, which is one of the most important raw materials in production of steel. There are many large-scale iron ore area which have high value of exploitation in Australia, Brazil, India, Canada, USA, Ukraine, Liberia and other countries. Main iron ores are magnetite, hematite, limonite, iron silicate ore, iron silicate mineral, etc. The most commonly used crushers in iron ore mining industry are jaw crusher, impact crusher, hammer crusher and high-efficient iron ore fine crushers, etc. In iron ore mining, customers usually choose a complete iron ore crushing production line for higher efficiency. At present, the most popular iron ore production line consists of two jaw crushers. After crushing, the material will be sent for the magnetic separation, and then into the ball mill for grinding.
It's important to choose different crushers for different demands. In order to achieve higher production efficiency, our engineers designed a more efficient crushing and screening process:
In order to make the materials size as fine as possible before entering into ball mill, the crusher must have an excellent fine crushing capability to minish iron ore size. To achieve this crushing effect, two grades of jaw crushers and one fine crusher (high thin broken machine) are applied in the production line. Two grades of jaw crushers are coarse and fine jaw crushers which are commonly used types in crushing. Tertiary fine crushing machine is the key of the whole production line. Widely used fine crushers are hammer crusher, impact crusher, and cone crusher etc.
Iron ore crushing plant components
Storage bin, vibrating feeder, cone crusher such as spring cone crusher, CS Cone Crusher, hydraulic cone crusher and so on, ball mill, belt conveyor, screw separating, magnetic machine, floatation, concentrator, drier and so on.
Iron ore crushing plant with high capacity management
When customer needs a capacity above 150t/h by one crusher, we'd better think about cone crusher. Cone crusher is a typical crusher adopting the principle of inter-grain laminate. It is characterized with a long life span of wear parts. Usually, the life span of the wear parts (concaves, mantles etc.) in the tertiary crushing can reach up to about three months. Long duration of wear parts saves a great cost for customers, and highly decreases the workload of maintenance.
Cone crushers are widely applied in iron ore crushing, especially in big quarry crushing. It is divided into types of spring cone crusher, multiple cylinders hydraulic cone crusher and single cylinder hydraulic cone crusher.
Comparing with spring cone crusher, multiple cylinders hydraulic cone crusher has great improvement in adjusting structure and iron crushing devices. However, there is no essential difference in working principles between spring cone crusher and multiple cylinders hydraulic cone crusher. Therefore, the discovery of single cylinder cone crusher is a great break through. With precise processing and manufacturing, the price of single cylinder cone crusher may be double or several times higher than spring cone crusher and multiple cylinders hydraulic cone crusher.
Of course, which type of crusher should be choose in quarry and mining depends on customers’ specifications and actual situations.
