iron ore crusher
Our iron ore crusher is of very good quality, high crushing capacity, low power consumption, environment friendly and so on. It has been employed by several renowned iron ore mining and Beneficiation Firm, such like Vale, BHP, and Rio Tinto and so on.
Iron ore crusher would be the important crushing equipment applied in a stationary iron ore crushing and screening plant. As a expert iron ore crusher manufacturer and exporter , SBM can generate the iron ore crusher from primary crushing to tertiary crushing, we even can provide the clients with portable crusher and mobile crusher .
Iron ore crushing plant
Iron ore crushing plant plays an vital function in iron ore mining and beneficiation. SBM Iron ore crushing plant will equip with distinctive crushing equipment from main crusher, secondary crusher, tertiary crusher, washing equipment, sieving equipment and transferring equipment based on the web site along with the demands with the customers.
As a significant iron ore crushing plant manufacturer and supplier in China, our stationary iron ore crushing and screening plant works as follows:
Firstly, the main heavy duty crusher will minimize the run-of-mine iron ore as much as 1.3 meters in diameter into lumps about the size of a football feeding by vibrating feeder , it is actually then transferred to a secondary crusher by heavy duty conveyor belt, exactly where the sized iron ore is broken down into grapefruit-sized lumps. Then the crushed iron ore will likely be transferred to sieving equipment for grade. The oversize is returned for tertiary crushing soon after which it becomes component of the feed towards the product screens. Secondly, soon after the crushing procedure is over, the sized iron ore will probably be sent to a concentrator where waste shale and low-grade ore is removed so the saleable lump and fines goods may be produced. Thirdly, a washing plant is required to remove the ultrafine iron ore. Right after the washing process, the final iron ore merchandise are produced. Then it will be transported to a stockpile.
Iron ore and its usage
Iron ore is among the most typical minerals in the earth' crust. Following the iron ore is mined and processed in an iron ore beneficiation plant, iron ore is created into diverse products for everyday life.
The important four usage of iron ore are:
1) Cast iron: it is perfect for moulded parts, like automobile engine blocks.
2) Wrought iron: it really is suitable for use in outdoor furniture, porch railings along with other decorations.
3) Steel: it's a great material for a large number of diverse makes use of.
4) Stainless steel: it's an ideal material for motor vehicle parts, hospital equipment and food preparation tools and utensils.
Ore crushing is actually a crucial method to manage the run-of-mine ore minerals like iron ore, gold, bauxite, copper, manganese, nickel, coal etc. at ore dressing plant. Usually, three phase crushing procedure are going to be adopted to cope with ores: coarse crushing, medium crushing and fine crushing. The well known ore crushers are jaw crusher , hammer crusher , impact crusher , cone crusher and VSI crusher.
The ore crushing process goes as follows:
Raw ore minerals ->jaw crusher -> impact crusher -> cone crusher (VSI crusher) -> final items in distinctive grade.
Through the coarse crushing by jaw crusher, the size of ore is less than 1m in diameter, and right after medium crushing, the crusher breaks down boulders into lumps about the size of a footballand fine crushing, the size will be reduced to less than 12mmwhich is ingrapefruit-sized lumps.
From there, it is actually sent to stockpiles. Waste rock from the mine, which is low in ore mineral content, is retained for use in rehabilitation. This forms a closed cycle.
Ore grinding process
Ore grinding approach plays an significant role in ore beneficiation plant. The ore milling machine grind the crushed ore minerals into fine even ultrafine powder so that the leaching and smelting procedure can go smoothly.
Ore grinding mills might be divided into wet grinding and dry grinding. Based on the distinctive application, there are going to be open-circuit grinding and closed-circuit grinding procedure. Probably the most preferred ore milling machine are SAG mill, ball mill , Raymond mill , vertical mill , trapezium mill .
Our engineer will design diverse grinding lines for the customers based on customers’ requirements plus the nature with the minerals.
Ore dressing plant is a significant portion of ore beneficiation plant.Usually, we will equip the ore dressing plant with jaw crusher, impactor, cone crusher, ball mill, trapezium mill, classifier, magnetic separator, flotation machines, thickener, dryers along with other ancillary equipment like conveyors, vibrating feeders, screens, washers etc. The whole unit feature with high efficiency, low power consumption, high capacity, economical and so on.
The flow chart is:
Big raw ore minerals are fed into the heavy duty jaw crusher evenly and gradually for primary crushing, Soon after the coarse crushing, the crushed ores will be conveyed to impact crusher for medium crushing, finally, the crushed ore might be transferred to cone crusher (VSI crusher either) for fineness crushing. When the crushing method is finished, the ores will be separated by sieving equipment like multi-deck vibrating screen . Then, the crushed ores will likely be transported to grinding plant for ore grinding.
The ore grinding plant will grind the ore into powder less than 0.4mm, then classification method goes on. The spiral classifier can washed and classified the mixture ore. Immediately after classifying, ore particles are sent to flotation machines, depending on the mineral characteristics with distinctive chemicals, making the required ores and other materials to be separated.
At the beneficiation plant, the ores might be leaching and smelting in the smelting furnace.
