Iron ore mining methods vary by the kind of ore being mined. You can find four major forms of iron ore deposits worked currently, with respect to the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
Iron ore refers back to the ore containing iron or iron compound, which is one of the most important garbage in output of steel. There are many large-scale iron ore area which have high value of exploitation australia wide, Brazil, India, SA, Canada, Ukraine, Liberia as well as other countries. Main iron ores are magnetite,limonite, hematite ore, iron silicate ore, iron silicate mineral, etc. Probably the most widely used crushers in iron ore mining business are jaw iron ore crusher, cone crusher, hammer iron ore crusher and high-efficient iron ore fine crushers, etc. In iron ore mining, consumers usually choose a complete iron ore crushing production line for better efficiency. Currently, typically the most popular iron ore production line consists of two jaw crushers. After iron ore crushing, the fabric is going to be sent for the magnetic separation, and then in to the ball mill for grinding.
The worlds iron ore resources are concentration australia wide, Brazil, Ukraine, Russia, Kazakhstan, India, the usa, Nigeria, Canada as well as other countries. Nearly all iron ore experiences iron ore processing and it is utilized to make steel. Iron ore processing can be a procedure that contains explosions, shoveling, moving, crushing, grinding, pelletizing etc. Iron ore processing provides a range of coarse sizing that may produce material in 24-inch to .0017-inch particle sizes.
In iron ore crushing and screening process is really a basic connect to concentrator will have an effect on producing indicators. Methods accustomed to include jaw crushing, impact crushing, roll crushing, and pulverizing. To make iron ore size as fine as you can before entering into ball mill, iron ore processors usually are use cone crushers in pre-grinding stage, cone crusher come with an excellent fine crushing power to minish iron ore size. In coarse crushing, 2.1m or 2.2m gyratory crusher is usually being selected, in medium crushing process, processer usually use regular cone crusher, plus fine crushing, short-head kind cone crusher would work.
Compound Cone Crusher, widely used in the industries of metallurgy, building material, road construction, chemical engineering & silicate, is suitable for crushing all kinds of ores and rocks with medium or above hardness. Compound Cone Crusher is divided into standard type and short-head type. Generally speaking, the standard type has big feeding granularity and relatively coarse discharging granularity, and the short-head type has steep crushing cone and small feeding granularity which is conducive to producing fine particle materials, for this reason,the standard type compound cone crusher is generally used for coarse and medium crushing and the short-headed type compound cone crusher is generally used for medium and fine crushing.
It has unique hydraulic clearing system,hydraulic opening adjusting function,easy for changing movable and fixed plate,decreasing management and maintenance cost. It is widely used for medium and fine crushing of granite,basalt,cobble,cobblestone,iron ore etc, which is well received by customers.
Cone crusher when working, the motor drives the eccentric bearing via the spring coupling, the transmission shaft and a couple of cone gear wheels. The crushing cone axis is forced to swing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl liner, and sometimes far away from the bowl liner. The raw materials are pressed, impacted and finally crushed in the copper.

Iron ore is an important raw material for iron and steel production enterprises. Iron is gradually selected from natural ore (iron ore) by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. It is a mineral aggregate containing iron or iron compounds that can be economically used. Any ore containing iron that can be economically used is called iron ore. There are many kinds of iron ores, mainly magnetite (FeO), hematite (FeO) and siderite (FeCO) for iron making. There are two characteristics of China's iron ore resources: one is that there are many lean ores, the reserves of which account for 80% of the total; the other is that there are more complex ores with multiple elements. In addition, the ore bodies are complex; some of the lean ore deposits are hematite and the lower part is magnetite. In view of the existing characteristics of iron ore in China and the higher requirements for iron concentrate in the iron and steel industry, new challenges have been posed to the Chinese ore dressing workers. Therefore, China's metallurgical mine beneficiation technology has a deeper development requirements, followed by the further improvement of mineral processing equipment.
Iron ore beneficiation can be divided into several different processes according to the type and nature of ores. Ore dressing plants usually use coarse crushing, medium crushing and fine crushing three stages crushing process to crush iron ore. In the iron ore crushing production line, in order to improve the production efficiency of the iron ore crusher and reduce the production cost, it is often necessary to crush the iron ore as fine as possible and crush the iron ore to the smallest particle size in order to achieve more crushing and less grinding. After the practical experience of iron ore processing and user feedback, the industry believes that the cone crusher for fine crushing of iron ore is the best. Specific process of iron ore crushing production line: iron ore is evenly sent to jaw crusher of iron ore crusher by vibrating feeder for coarse crushing, coarse crushing materials are sent to cone crushing by belt conveyor for further crushing, crushed materials are transported to vibrating screen for screening, to meet the requirements of particle size of finished materials through Belt conveyor conveys to the finished product stack; materials that do not meet the size requirements of the finished product are returned from the vibrating screen to be crushed or finely broken cone, forming a closed-circuit cycle. The particle size of iron ore pulverizer can be combined and graded according to the needs of users. Iron ore is an important raw material for iron and steel production enterprises. Iron is gradually selected from natural ore (iron ore) by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. In theory, any ore containing iron or iron compounds can be called iron ore; however, in industry or commerce, iron ore is different from manganese ore, iron ore not only contains iron, but also must have the value of utilization. After being mined out of the mine, the iron concentrate is treated with mineral processing equipment into about 65% iron concentrate, which is then taken to smelt into sponge iron, and then steelmaking.
JXSC Compound cone crusher is improved modified by Symons cone crusher, which is the high-performance cone crusher that introducing advanced foreign technology. The crusher equipment has product characteristics of superior quality and reliable performance. The crusher equipment adopts the best combination of crushing frequency and eccentric distance, which makes the crushed materials have a higher crushing degree. The crushing productivity is higher than other crushers. The crushing equipment's operation becomes more automatic because it uses the devices of hydraulic safety, hydraulic lock, hydraulic adjustment, hydraulic cavity cleaning, etc. Compound cone crushers are widely used in sand plant and crusher plant as secondary or tertiary crusher machine. Feeding size: 80-300mm. Capacity: 60-610tph.
Application Field: Quarry, mining, coal mining, dry powder mortar, concrete mixing station, power plant desulfurization, quartz sand, etc. Suitable Material: Pebble, granite,basalt, iron ore, limestone, quartz, diabase, iron ore, gold, copper, etc.

With large diameter spindle, heavy mainframe and independent of the dilute oil lubrication automatic control system which ensures the equipment is durable reliable operation. Hard protection device can ensure the impurities through the crushing chamber. Then the machine rapid restoration of normal operation.
2. Repair is convenient and easy to operate. All the parts are capable of dismounting from the upper or side. It uses a sliding bearing, compared with the rolling bearing. It not only has the bearing performance better but also more economical, more convenient repair.
3. Low cost and a wide range of applications. Large capacity, high reliability, convenient repair, low operation cost. It can be used for material high hardness materials and low hardness of coarse crushing and fine crushing work.
4. High crushing ratio, high efficiency, and energy-saving, crushing cavity, cavity cleaning convenient, stable performance, firm structure, convenient maintenance, low cost, good sealing performance, little flakiness content.
When the composite cone crusher working, the motor drives the eccentric sleeve to rotate via the belt, a big belt wheel, transmission shaft, bevel gear, bevel gear. Crushing cone axis swinging under the force of the eccentric sleeve, the surface of the broken wall sometimes close to and sometimes leave the rolling mortar wall surface. Material impact, extrusion, bending and crushing, in a ring crushing cavity of the fixed cone and moving cone. After repeated extrusion, impact and bending, material crushing to the required size, discharge from the outlet.
The first cone crusher in the world is invented by Milwaukee Symons brothers in the 1920s. Symons cone crusher was named because of Symons brothers' names. Although it was not important news at that time, It has made a great contribution to the improvement of the later crushing equipment. If there wasn't the Symons cone crusher, there wouldn't the hydraulic cone crusher.
In 1984, the first hydraulic cone crusher was developed. When the non-crushed materials(such as ore) through the crushing chamber, the series of cone crushers is through the hydraulic system to expand the crushing chamber. Therefore, the on-crushed materials pass the crushing place. The hydraulic system protects the crusher from damage. In recent years, the technology, efficiency, function, maintenance costs of the cone crusher have been outstanding improved. Symons cone crusher needs to manual operation, but the hydraulic cone crusher can be controlled by an electric control system.
