Iron is the world’s most commonly used metal – steel, of which iron ore is the key ingredient, represents almost 95% of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications.

Iron-rich rocks are common worldwide, but ore-grade commercial mining operations are dominated by the countries listed in the table aside. The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist. The main constraint is the position of the iron ore relative to market, the cost of rail infrastructure to get it to market and the energy cost required to do so.

Over the last 40 years, iron ore prices have been set by a so-called benchmark system , between miners and steelmakers. In recent years, the benchmark system has begun to break down, with some miners pushing for their customers to use the spot market, and negotiations with the largest buyer, China, causing friction. As the spot market has grown in size and importance, financial hedging instruments such as iron ore swaps have emerged.

Iron ore reserves at present seem quite vast, but some are starting to suggest that the maths of continual exponential increase in consumption can even make this resource seem quite finite. The iron ore quarry mining process is complicated process and need many mining equipment. Through the mining process iron ore boulders are turned into all sizes of materials. The blasting process is the first step determining what needs to be accomplished next. Rock hammers, drop balls, primary crushers, and gyratory crushers all contribute to the iron ore mining process. Coarse materials are sent by belt conveyer to the iron ore crushing plant or iron ore grinding plant for additional crushing, grinding and sizing. The mine stockpiles different sizes of iron ore materials for their customers.

There is a specific operating speed for most efficient grinding. At a certain point, controlled by the Mill speed, the load nearest the wall of the cylinder breaks free and it is so quickly followed by other sections in the top curves as to form a cascading, sliding stream containing several layers of balls separated by material of varying thickness. Grinding Mill Price, the grinding influencing factor said broadly, stave process influencing factor including material nature, detritus equipment performance and operating condition.

One: Material nature kind of influencing factor mainly includes the material the degree of hardness, density, the average gradings and structures, water content, silt carrying capacity. The material degree of hardness is bigger, not easy stave; The density of material is bigger, is bigger according to the equipment handling ability that giving the material counts; When the greatest granularity of material is certain, the average gradings are thinner, needs the breaking work load to be less; The structure relaxation and jointing growth good material is easy, but the watery and silt carrying capacity big material are easy to cake, when is serious will cause the stave cavity jamming.

Two: Detritus equipment performance kind of influencing factor mainly includes the type, specification and the dump mouth equipment and gnaws the angle. The type and specification of detritus equipment are to decide it whether to satisfy the specific work request the first condition, thus when the choice detritus equipment, must first act according to treats the broken material the nature and quantity, determined that uses any type the equipment and specification. On a concrete equipment, the dump mouth’s size in fact is deciding its work quality and productivity. When the throat is over sized, majority of materials without stave through dump mouth, thus makes the productivity very big, but the reduction ratio is small;

Otherwise, when the dump mouth is too small, although the reduction ratio will increase notably, but the productivity of equipment actually therefore seriously drops. The when gnawing angle of detritus equipment is to refer to being caught in the pincers of material block, the included angle between stave working part surfaces, usually indicated with mark a. When according to this definition, the gnawing angle of jaw breaker is being caught in the pincers of material block, moves the jaw with deciding the included angle between jaws, but the gnawing angle of roller breaker is to refer to the included angle between material blocks and two roller surface contact tangents. The detritus equipment gnawed a jiao size to decide directly whether the stave process can carry on safely smoothly, was a very important equipment operational parameter.

Three: Operating condition influence grinding process operating condition mainly to material the work form of condition and detritus equipment. Continuously evenly to the material both can guarantee that the production normally is conducted, and can sharpen the productivity and working efficiency of equipment. In addition, when the close up is stave, the productivity of breaker may increase 15% – 40%.

In extractive metallurgy, mineral processing, also called mineral dressing or ore dressing, is the procedure of separating commercially valuable minerals using their ores. Mining Processing Machinery include crushing equipment,grinding equipment,Gravity machine, flotation machine and Magnetic separation …

Ahead of the advent of heavy machinery the raw ore was split up using hammers wielded by hand, a procedure called “spalling”. In a short time, mechanical means put together to achieve this. For example, stamp mills were chosen for Samarkand as early as 973. These were also being used in medieval Persia. By the 11th century, stamp mills were in widespread use through the entire medieval Islamic world, from Islamic Spain and North Africa in the western world to Central Asia inside the east. A later example was the Cornish stamps, that includes a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling about the ore under gravity.

The easiest method of separating ore from gangue contains the selecting the individual crystals of each and every. This can be a very tedious process, particularly when the person particles are small. Another comparatively simple method depends on the various minerals having different densities, causing them to collect in different places: metallic minerals (being heavier) will give up of suspension quicker than lighter ones, that is carried further by way of a stream of water. The process of panning and sifting for gold uses both these methods. Various devices known as ‘buddles’ were chosen to consider good thing about this property.

Dryer can be used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be utilized for drying many kinds of materials along with convenient and reliable operation.

This machine is principally found in ore selecting, building materials, metallurgy and chemicals to dry the types of materials with certain moisture and size. The rotary drier includes a strong adaptability which could dry many different types of materials having a simple operation method and security trait, so it is traditionally used.

Ball mill is surely an efficient tool for grinding many materials into fine powder. The Ball mill is utilized to grind many kinds of mine as well as other materials, or select the mine. It is traditionally used in building material, chemical industry, etc. There are 2 means of grinding: the dry process as well as the wet process. It may be split into tabular type and flowing type in accordance with various forms of discharging material.

Magnetic Separator can separate the raw materials with various magnetic rigidities. The device works beneath the magnetic force and machine force. Magnetic Separators are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for many applications. The center of every separator will be the magnetic system with its unique design, with a proven record of high efficiency.

There are many important ores and medals deep inside the earth. The only way to get them out is through extensive mining. Mining is a back breaking, grueling process. Mining machines have helped to streamline mining by speeding up the process and creating safer working conditions. Mining machine operators run these machines and keep them working properly and efficiently. Many skills must be mastered before becoming a mining machine operator.

Physical Skills

Even though mining machines are designed to lighten some of the physical load of mining, a mining machine operator must possess advanced physical skills. He must be able to move multiple limbs at any given time. For example, he may need one hand to steer the machine, another hand to control the digging apparatus and one foot to press the gas pedal. He must have steady arms and hands. Shaky hands at the controls can cause sudden jerking motions that could contribute to accidents in a mining situation. They must also have good reaction time in case of a sudden dangerous situation. In these cases, depth perception, hearing sensitivity and far vision are also essential. These skills help to spot and avoid problem situations before they occur.

Mechanical Skills

A fertilizer spreader is a metal hopper with an adjustable trough underneath for applying an even layer of fertilizer over lawns and gardens. Some spreaders connect with a tow hitch to the back of a tractor. Smaller models have a handle and wheels for pushing the spreader yourself. As with all garden tools, cleaning your spreader after each use will prolong the life of the equipment and ensure proper operation. A garden hose may be used, but a power washer works best.

1. Empty the hopper of all fertilizer, either by spreading the product on your garden or lawn or removing the fertilizer and returning it to its storage bag.

2. Open the hopper trough at the bottom of the spreader so water can run through. Pull the lever on the side of the spreader to open the trough.

3. Wash the spreader inside and out with a garden hose or power washer. The power washer works faster to remove fertilizer particles that may have dried and hardened on the equipment.

4. Wipe down the spreader with old towels to remove excess water, and allow the equipment to air dry completely.

5. Pour machine oil on an old towel to wipe down metal parts, concentrating especially on the hinge mechanism at the bottom of the spreader trough.

Henan Hongxing Machinery is one of the primary mining machinery manufacturers based in China. All our mining machinery including fertilizer production machines are designed based on latest production technologies.

Currently, we can produce variety of different fertilizer equipment, including disc granulators, rotary drum granulators, dryers, fertilizer cooling machines, and screening machines, etc. Owing to their simple structure, convenient adjustment, superior performance, long service life and environmental protection, our fertilizer equipment is widely used in fertilizer manufacturing industries for transportation, drying, cooling and screening non-glutinosity materials.

Fertilizer equipment comes in several forms. Many pieces are designed specifically to apply various kinds of fertilizer. Other pieces that can be categorized as fertilizer equipment include mixing tanks, holding tanks and equipment specifically intended for use in applying anhydrous ammonia to agricultural land.

Dry forms of fertilizer are usually applied with a type of fertilizer equipment known as a spreader. Drop spreaders dispense fertilizer from the bottom of the holding container through a mechanism that regulates the rate of application. Broadcast spreaders throw the fertilizer in swathes around the equipment. Both drop and broadcast spreaders come in a huge range of styles and sizes ranging from hand-held units for small home gardens to giant pieces of equipment that are towed behind agricultural tractors.

Liquid fertilizers are applied using sprayers. The most common type of sprayer for use in yards and gardens is a tank small enough to be carried by hand or on the operator’s back. The fertilizer flows through a hose with a spray nozzle on the end. Fertilizer equipment for spraying on a larger scale normally has a row of nozzles mounted horizontally on a pipe that attaches to a tractor or other vehicle. These are called boom sprayers and also come in a range of sizes.

Specialized fertilizer equipment is necessary for use with anhydrous ammonia, a source of nitrogen for fertilizing large areas. Anhydrous ammonia is stored as a liquid under high pressure and becomes a gas as it moves into air at normal pressure. The liquid is very cold, caustic and corrosive, so it must be handled carefully. Storage tanks, hoses, nozzles and other parts of the spraying equipment used for anhydrous ammonia must be carefully designed and maintained. Anhydrous ammonia becomes a gas at normal pressure, so the fertilizer equipment injects it into the ground instead of spraying it on the surface.

Papermaking is the process of making paper, a substance which is used universally today for writing and packaging.

In papermaking a dilute suspension of fibres in water is drained through a screen, so that a mat of randomly interwoven fibres is laid down. Water is removed from this mat of fibres by pressing and drying to make paper. Since the invention of the Fourdrinier machine in the 19th century, most paper has been made from wood pulp because of cost. But other fibre sources such as cotton and textiles are used for high-quality papers. One common measure of a paper's quality is its non-woodpulp content, e.g., 25% cotton, 50% rag, etc.

No wood, no water, use the 'rock paper', you heard it? This is known as 'rock paper' The advent of new technology, known as the traditional paper and packaging materials in the field of a major technological breakthrough. Different from traditional paper timber, paper, stone, the main raw material is most abundant in the crust of calcium carbonate mineral resources, as well as 20% of other accessories and additives as raw materials, production of processed polymer processing technology, a breakthrough was followed 2000 years in wood pulp, straw pulp as raw material, paper making technology. Rock paper technology, is the most abundant mineral in the crust of calcium carbonate as the main raw material resources to a variety of polymer materials and inorganic substances as auxiliary materials, use of filled polymer interface chemistry and modification, a special processing and into a reversible cycle of use, technical characteristics of modern technology the new paper. The birth of the technology, not only to solve the traditional paper making pollution on the hazards in the environment, but also solve the Daliang caused by the use of plastic packaging white pollution and waste a lot of oil resources issues.

The main part of paper-making process stone is rock grinding, rock paper directly affects the toughness of paper, and break resistance, waterproof and oil and other characteristics. There are many rock grinding equipment, such as raymond mill, high pressure suspension mill roller, vertical milling machines, milling machines and other European milling process can be completed, but the stone paper, the extraction of rock in calcium carbonate, then the purpose of ore ground into fine powder calcium 1500-2500, followed by a second process, will add on 85% of modified calcium carbonate made of 15% of the additive masterbatch, and finally through the extrusion blown film equipment made of paper or bags.

A modern paper mill is divided into several sections, roughly corresponding to the processes involved in making hand-made paper. Pulp is refined and mixed in water with other additives to make a pulp slurry, the headbox of the papermachine (Fourdrinier machine) distributes the slurry onto a moving continuous screen, water drains from the slurry (by gravity or under vacuum), the wet paper sheet goes through presses and dries and is finally rolled into large rolls, often weighing several tons.

Compared to the traditional paper technology, rock paper technology without wood, without bleaching, no waste water pollution, protect forests, protect the environment, a new technology to benefit mankind.

Cone Crusher is a kind of new type crusher who adopts the new crushing concept, its structure principle entirely different from Jaw Crusher, hammer crusher, Impact Crusher and other crushing machine. Its Crushing capacity and unique production ability are other types of crusher can't be compared.Cone crusher is divided into spring cone crusher and Hydraulic Cone Crusher, suite for crushing the stone and rock which hardness is above average.

Cone crusher is dividing in to standard type, short type, generally used in middle and fine crushing. Standard type, generally used in second crushing, Short head type, generally used in fine crushing.Spring cone crusher has four Chambers that is especially coarse, coarse, medium, small type.The principle of selection is to look at the feed particle size and particle size of the decision to discharge into the Liao duo large, coarse particle size, choose special coarse or coarse, and vice versa type of medium and fine. In the calculation of particle size, the open side with the largest population size multiplied by 0.85 feed into the material size as a selection based on the average size of the product is divided by the maximum feed crushing ratio.

Spring cone crusher standard used for open loop, short head type is used for closed loop. When choose the scale board, users consider three factors generally, that is capacity, power dissipation, wearing resistance of the scaleboaed. Should be abbey the following principle: Maximum feed size; size changes to the particle size distribution; material hardness; material wear resistance? The higher the longer the power liner, hard-liner material selection is short, long soft liner material selection, the distribution of the material, fine material selected short liner, long liner thick material selection. Feed particle size distribution, in general, less than the closed side of the nesting population cannot exceed 10% of the material, if more than 10%, the increase in power consumption, product size becomes flaky. Viscous material increase in the amount of moisture can affect the throughput of materials; the material is water, generally no more than 5%. The use of the power, the cone crusher should pay attention to following issues when in operation, can make sure the normal work for machine.

Cone crusher at work, feeding should be uniform, not segregation. If the feed to reduce production capacity will be uneven, the product particle size is too large, the spring moves frequently, Bowl-bearing pressure, power consumption increased. Have iron device; to prevent the crushing chamber through iron, iron if too frequent, it may cause broken accident

Interested in saving money on a backhoe, loader, jaw crusher, sand maker or belt conveyor? Sometimes, buying used mining, construction or heavy equipment is a smart way to go and makes sense. Other times, you'd be better off going home empty handed. Here are a few ways you can make sure you get a good deal on used construction equipment.

Look carefully...

Go over the used equipment you're investigating slowly and carefully. New paint jobs are relatively cheap and can cover up a lot of problems. Look for evidence of rust patching or cover-up – poke suspect areas with a tool to be sure. Check underneath the vehicle for evidence of leaks. Inspect hoses and valves before and after the test drive, so you easily spot fresh leaks.

... but use all your senses

When you're testing out used construction equipment, don't go by your eyes alone. Listen to the engine and the hydraulics as you're testing it out – is the machine straining more than it should? After it's been running for a while, are there any smells of burning oil or electrical problems? Do the controls feel as responsive as they should?

Review Maintenance Records

Most users keep a history of all the maintenance repairs performed to the equipment. Many log hours against the actual components and requesting these would be very prudent and helpful for your assessment. Engine hours may differ from hours on hoist cylinders or tracks for example so understanding the life of components will help you determine fair market value.

If possible, buy from established companies or dealers

You are much more likely to have problems if you buy used construction equipment from individuals or a business that does not focus on construction or mining. Mining Machinery companies have several advantages when it comes to used equipment:

a.They have a reputation in the industry;

b.They know that if you're buying used equipment now, you're likely to need more equipment in the future and making sure you are a return client is important to them;

c.They have regular P.M. schedules and equipment is likely to be better maintained then if purchased from a small unknown company;

d.They're better able to inspect and repair any potential problems with the equipment as they have the staff on hand to maintain the equipment;

With these tips in mind, you should be able to find a used piece of construction equipment that can still get the job done.

In the national stimulating domestic demand policy, under the support of most of the enterprise take the structure adjustment, strengthen the competitive power of characteristic advantage industry at home and abroad, and constantly open up the market, prompting juki industry is still maintained a fast and steady growth.

In the current environment, economic development demand for energy is more urgent than ever before, and the needs of a mine construction and crusher mining equipment market climax of 'hot' particularly noticeable.

Since always, coal-based China's energy structure decides the construction of large coal mine, and now the government thought in an unprecedented attention high efficiency and energy saving of the environment, construction of large open-air coal mine will be China's energy construction point one of the development direction. As countries to strengthen the construction of the mine resource efforts, the boom of the mining construction is to mining equipment all big manufacturers to provide a good market opportunities. China's mining equipment production enterprise, such as crusher enterprise, but also are taking measures for the mining construction cake to share more share.

The current our country in the south in coal mine enterprises mechanization level relative low some, but on the whole, mining machinery large compound mining equipment will be even more widely used. Mining machinery technology equipment level of ascension, will promote the modernization of the coal mine enterprises, improving continuously, m&a continuously strengthen production safety.

Tucked away in the northeastern section of Beijing just outside the Fourth Ring Road stands what was once the pinnacle of Chinese industry. The scale of China's manufacturing capacity and its domestic market for machinery are remaking the industry's international landscape. China's dynamism presents opportunities for foreign machinery makers as an export and investment destination, as well as an up-and-coming source of capital. Mining machinery is the machines directly used for the mineral mining and beneficiation, including mining machinery and mineral processing machinery. Broadly speaking, exploration machinery also belongs to mining machinery category. In addition, many other equipments like cranes, conveyors, fans and drainage machinery are also applied in mining operations.

Mining machines are the equipments used for the exploitation of valuable minerals including digging machinery for the mining of metal ores and non-metallic minerals, coal mining machinery for the mining of coal, oil drilling machinery for the exploitation of oil, etc. The first wind moving wafer shearer was designed by a British engineer named Walker, and was successfully manufactured in about 1868. Beneficiation is the process of choosing valuable minerals from the collected raw materials according to their differences in the physical properties, physicochemical properties and chemical properties. The machinery that implemented this choosing process is called beneficiation machinery. Beneficiation machinery can be divided into crushing, grinding, screening, sorting and dehydration machines. The commonly used crushing machines are jaw crushers, gyratory crushers, cone crushers, roll crushers and impact crushers and so on. Drum mill is one of the commonly used grinding machines including rod mill, ball mill, pebble mill, etc. Hydraulic and mechanical grading machines are widely used in wet classification work.

China's main cost advantage is, of course, inexpensive labour. As a corollary of having the world's largest population, China also has the world's largest labour force. The machinery industry alone currently employs around 20 million people, and they are paid wages far lower that those paid in any other major machinery producing country. Much of the resulting cost savings are then transferred to international consumers via lower product prices for exports. Although wages in China have increased substantially in recent years, the average rate of USD 0.40 per hour in 2008 was well below the rates of the US, Japan and Germany, all with hourly wages above USD 20.

Currently there are two problems existed in China's mining machinery industry. First, the comprehensive strength of the mining machinery enterprises is not strong. The majority of enterprises are at a standstill of energy and capital investment in scientific research, new product development, technological innovation and enterprise management. Variety of domestic mining machinery products can not meet the various requirements, especially the critical needed key equipments for the national construction. And there are problems of low technology content, low additional value and unstable quality of products, low labour productivity and so on. Second, a series questions of product variety, technology, quality, service, etc. have led to the low actual contribution rate of the mining machinery industry to the domestic mining industry. Henan Hongxing Mining Machinery Co., Ltd. lays much emphasis on the quality and clients. We serve clients with the quality guideline of being responsible for every working procedure, every product and every client. What we have done is for the clients and we believe that quality is the best way to develop market. All of the products have passed the authentication of ISO9001. Hongxing Brand is the Chinese Famous Brand. Reliable and stable quality is the key to success. Our products are well known at home and abroad. Now we have tens of thousands of users throughout China and more than 30 world markets.

As China's machinery industry continues to progress, the question for the international manufacturer is how to react. A number of strategic options are available for international firms to integrate their businesses with China's machinery-making potential. Although China is the world's largest exporter of machinery, the opportunity still exists to export to and invest in certain products to China, particularly for innovative products using cutting-edge technology. It is often a matter of pride for Chinese manufacturers and a symbol of quality to have foreign-made capital equipment. When touring a Chinese factory the manager will often boast of possessing a German or American-made production line. The reputations conferred by the brand names of international companies still outweigh those of Chinese brands—Caterpillar is far more renowned than Henan Hongxing. Foreign firms are also noted for their after sales service, an area still relatively unemphasised by Chinese companies.

In the 1970s, China's financing and construction of a 1,870 km-long railway giving landlocked Zambia access to the Tanzanian port of Dar es Salaam was a monument to Chinese engagement and solidarity with Africa in a previous era. In a flush of post-colonial exuberance, Africa was undergoing a construction boom. The China that built the railway in Africa in the 1970s is a distant shadow of the China of today that routinely builds railways, roads, ports and other infrastructure in various parts of the world. In the 2000s, as the size of China's economy in quick succession surpassed that of Italy, France, the UK, and Germany, China's energy consumption expanded four times faster than expected to 16% of global demand in 2006.

Instead of a boom of new steel and concrete, Africa experienced decades of lost growth. In 2008, the World Bank estimted that access to the most basic services in Africa increased only modestly between the early 1990s and the early 2000s, and only slightly in the last decade. Electricity, for example, is still available to little more than 20% of Africa's total population, and piped water to just 12%.

Yet now a new China with vastly different priorities and strategic outlook is back in Africa, where it is instrumental in Africa's new construction boom that is reshaping the business landscape on the continent. In contrast to its piecemeal interaction with African countries in previous decades, China is now comprehensively engaged with almost all of Africa's 54 countries – lending money, providing aid, trading, investing, and more than all else: building infrastructure and extracting resources. This over-simplified description of China's business in Africa goes to the heart of how Africa's business landscape is changing under the influence of a new superpower hungry for natural resources and well-suited to provide Africa with something it is sorely in need of: infrastructure.

Along with the US and emerging economies such as Brazil and India, China's imports from Africa are as expected characterised by a disproportionate share of oil and minerals. China's trade with Africa has as a result been very lucrative for resource-rich African countries, and these African commodity suppliers have become crucial suppliers for China. South Africa is China's only African trade partner from which it imports substantial amounts of products that are not resources, while China's leading suppliers of oil (Angola), Manganese (South Africa), chromium (South Africa), cobalt (the DRC), and platinum (South Africa) are all African.

In 2011,Janpan earthquake, China contributed amount of people and finance, and also machinery such as excvavtors, cranes, jaw crushers, impact crushers, belt conveyors and so on. Africa is now China's largest market in terms of contract revenue with 41.1%, even more than Asia with 36%. Similar to Chinese trade and investment in Africa, the revenue of Chinese contractors is highly concentrated in a few resource-rich countries. In 2009, the leading six countries (Algeria, Angola, Sudan, Nigeria, Libya and Ethiopia), mostly oil and gas-related economies, accounted for USD 18.1 billion or 71% of China's total revenue (see chart below).

In April, a Chinese official acknowledged that China is on the verge of overtaking the US to become the world's biggest consumer of energy. To keep up with demand, China's natural gas imports more than doubled to 6.3 billion cubic meters in Q1 2011 from a year earlier. China also plans to invest RMB 400 billion (USD 62.54 billion) in the construction of four hydroelectric dams to boost the share of non-fossil fuels in national energy consumption. Wind power is also a part of this strategy as China will boost its offshore wind power installed capacity to five gigawatts to form a complete technological and industrial chain.

An uncertain global economic outlook due to the ongoing debt crisis in the Euro zone and the recent downgrade of the US debt rating, along with a large scale power crisis during the busy summer season are threatening to slow China's growth in the second half of 2011. However, looking to diversify its export destinations and build upon its status as the world's second-largest economy, China has continued to increase its footprint around the world, with Premier Wen Jiabao signing USD 15 billion worth of deals in Germany in June along with an additional USD 4.3 billion worth in the UK.

In April, Shanghai Electric Group Co. announced it had won a USD 1.1 billion contract to expand a natural gas-fired power plant currently under construction in Zubaidiyeh, southeast of Baghdad. The company also announced in April that they had signed an agreement with KSK Energy of India to export 125 units of 2 MW wind turbines to India, which marks Shanghai Electric's first major international wind turbine sale. The company expects India to become its largest export market, absorbing half its exports including wind turbines and thermal power units.

It was reported in August that Apple is currently in talks with China Mobile, the world's largest carrier by subscribers, to officially introduce the iPhone on the carrier's home-grown TDSCDMA network. A mutually beneficial deal would help Apple meet upwardly mobile Chinese consumers' growing demands for its products, while helping China Mobile attract more 3G subscribers. Although it seems unlikely that Apple will meet its target of opening 25 stores in the mainland by 2012, its four existing stores are the most heavily trafficked Apple stores in the world.
