challenges and opportunities in the iron ore crusher market | industrial vehicle technology international

January 25, 2019, the Vale iron mine in Brazil experienced a dam break, which led to the closure of large-scale mines. At the same time, the two major mines in Australia, BHP and Rio Tinto, were affected by the hurricane to reduce their shipments.

Since the end of January this year, iron ore prices have risen sharply, far exceeding the increase in steel and other raw materials. Therefore, iron ore has become the most popular investment in the eyes of investors. In July 2019, the price of iron ore reached more than US$120 per ton.

For the time being, the investment prospect of iron ore is very bright. So what is the global reserves and distribution of iron ore? How much does it cost to build an iron ore processing line? This article will answer you in detail.

The data released by USGS in early 2005 showed that the global iron ore reserves were 160 billion tons, the reserves of mineral iron (ie, iron contained in iron ore) were 80 billion tons and the basic reserves were 180 billion tons.

The worlds iron ore is mainly reserved in Ukraine, Russia, Brazil, China and Australia. The reserves are 30 billion tons, 25 billion tons, 21 billion tons, 21 billion tons and 18 billion tons respectively, accounting for 18.8%, 15.6%, 13.1%, 13.1% and 11.3% of the worlds total reserves respectively.

In addition, Kazakhstan, the United States, India, Venezuela and Sweden also have rich iron ore resources, and their iron ore reserves are 8.3 billion tons, 6.9 billion tons, 6.6 billion tons, 4 billion tons and 3.5 billion tons, respectively accounting for 5.2%, 4.3%, 4.1%, 2.5% and 2.2% of the worlds total iron ore reserves.

The worlds mineral iron is mainly reserved in Brazil, Russia and Australia, with reserves of 14 billion tons, 14 billion tons and 11 billion tons respectively, accounting for 17.5%, 17.5% and 13.8% of the worlds total reserves. The sum of the reserves in the three countries accounts for 48.8% of the total reserves in the world.

Mineral iron reserves and basic reserves are the most representative of the richness of a countrys iron ore resources, so Brazil, Russia and Australia are the worlds richest iron ore resources. At the same time, it shows that although Ukraine and China have large reserves of iron ore, they have more lean ore and less rich ore.

Iron ore resources are mainly reserved in more than10 countries, and 90% of proven reserves are distributed in10 countries and regions. They are: CIS (proven reserves of 114 billion tons, of which Russia is more than 80 billion tons), Brazil (68 billion tons), China (50 billion tons), Canada (over 36 billion tons), Australia (35 billion tons) ), India (17.57 billion tons), the United States (17.4 billion tons), France (7 billion tons), Sweden (3.65 billion tons).

The global iron mine reserves increased from 232 billion tons in 1996 to 370 billion tons in 2006, an increase of 59.5% in 10 years. The total amount of iron ore resources in the world is estimated to exceed 800 billion tons (the amount of iron ore), and the iron content exceeds 230 billion tons and there is still great potential for future discovery.

The major countries of iron ore resources include Brazil, Australia, China, Russia, Kazakhstan, Ukraine, the United States, India, Sweden, and Venezuela. High-grade ore is widely distributed in Brazil, Australia, India and other countries. The low mining cost and relatively high grade of iron ore make these countries the major iron ore suppliers in the world.

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.

The common problem in the iron ore crushing production line is that the wear parts of the fine crusher are seriously worn out, and the repair and maintenance of the fine crusher are too frequent, which makes the production efficiency of the iron ore crushing production line lower.

Different iron ore has different features. According to these features, the crushers are made of different materials. Therefore, the prices of iron ore crusher are different. However, reasonable crushing processes and crusher can be used to save the cost investment and achieve the required crushing effect.

In the crushing process of lean iron ore, in order to obtain the best process configuration and the lowest crushing cost, it is necessary to master the relationship of particle size among the primary crushing, the secondary crushing and the fine crushing.

For medium and low hardness lean iron ore, the second crushing equipment can use the impact crusher. The iron ore impact crusher utilizes a plate hammer on a high-speed moving rotor to produce a high-speed impact on the iron ore fed into the crushing chamber. The crushed iron ore is thrown at a high speed in the tangential direction toward the counter-attack at the other end of the crushing chamber.

During this process, the iron ore will collide with each other, causing cracks and looseness. When the iron ore particle size is smaller than the gap between the counterattack plate and the plate hammer, it is discharged outside the machine.

For high-hardness iron ore, a cone crusher can be used for the secondary crushing equipment. The HXJQ short-headed cone crusher can achieve a fine crushing effect of 3 to 13mm, which can fully meet the requirements of dry selection and grinding. However, due to the high hardness of such iron ore, the impact on the wear parts is large, so ordinary crushing equipment is difficult to exert its advantage.

In areas with low power consumption, the sand making machine developed and produced by HXJQ can achieve the fine crushing effect of high hardness and high output iron ore. Not only can the iron ore particle size be reduced to improve the dry selection efficiency, but also the ball mill load and operating cost can be greatly reduced, and the ball mill production capacity can be improved.

The price of iron ore crushing production line is related to various factors such as equipment combination, output level, and quality. Of course, the quotation standards of different manufacturers will also be different. Customers also need to analyze specifically when purchasing.

The comparison found that the price of the iron ore crushing production line of HXJQ Machinery is the most economical and reasonable, ensuring that the production line has a long service life, less failure, high efficiency, good effect, energy-saving and environmental protection, and can keep its price lower than other manufacturers 6% to 7%.

At the same time, the HXJQ configuration plan is all-sided, and there is a wide variety of equipment in HXJQ Machinery. If you are interested in these crushing equipment, please submit your relevant information on the right side, we will arrange a professional engineer to answer your questions.

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.
