As we all know, the cement is calcined at high temperature by the mixture of limestone and clay. In the cement production process, the first problem is crushing limestone. After many trials, transformation, developed various types jaw crusher which are classified into the coarse crushing and fine crushing jaw crusher. And the jaw crusher currently has been the most widely used crushing machinery.

Jaw crusher belongs to the deep cavity crushing equipment with long crushing stroke, which is good for material crushing and crushing process can be accomplished at once. And the size of the feeding particle can be 125mm ~ 1020mm. Jaw crusher can crush materials with a compression strength no more than 320Mpa, and it has a greater yield compared with similar products. The crushing method of jaw crusher is curved extrusion, the motor drives the belt and pulleys to make the jaw plate move up and down through the eccentric shaft. when the dynamic jaw rise, angle between the elbow plate and the dynamic jaw becomes larger, thus promoting the dynamic jaw plate close to the static jaw plate, and at the same time the limestone is extruded, rubbed, ground to achieve the crushing effect; when the dynamic jaw move down, the angle of toggle plate and the static jaw will become smaller, the static jaw plate will be far from the dynamic jaw plate at the function of the rod and the spring, at which time the crushed limestone will discharge from the mouth under the crushing chamber. And realize the volume production of the limestone along with the continuous rotation of the motor crusher periodic crushing and discharging. After many tests and improvements, jaw crusher break the crushing mode of hammer crusher which crush materials by directly impacting with the hammer of hammer crusher . And realize the aim of reducing the energy consumption.

The jaw crusher is mainly used as the the first crushing process of the crushing production line, it can be used alone as well as be used assembled with other crushing machinery. This series of jaw crusher has a obviouseconomic benefit in the installation and application of cement production line. Especially used in cement production line for limestone crushing, the jaw crusher has been song highly praise by cement users.

Henan Hongxing always stick to the entrepreneur idea that business reputation comes first, and we still carry out the service purpose of customer satisfaction and follow the business principle of “quality is the most important and our customers are God”, for this reason, Hongxing Brand mining equipment frequently is exported to the_middle East, South Africa and the Southeast Asia and is well received by customers.

Driving method of domestic over ball mill:

(1) It is driven by synchronous motor; Large-type adopts low-speed synchronous motor to directly drive the small pinion of ball grinder, and the small pinion will propel the big geared ring to make the ball machine rotate. Its advantages are of high transmission rate, low coverage size, easy maintenance and improved power grid rate coefficient, but the most is pretty expensive and needs direct electricity current.

(2) It is driven by asynchronous dynamo pinion speed lower sand maker machine. As for large and_middle sized ball grinder, it will adopt asynchronous driving method. The pinion speed lower machine drives the small pinion and big geared ring to rotate the whole equipment. Its_characteristics are that it cost less, but a whole complete set of big-size speed slower equipment is necessary.

(3) By asynchronous machine triangle belt. Small sized device uses asynchronous machine to put the tooth tyre in motion by way of triangle belt, but it has such disadvantages as low transportation capacity, big coverage size and complicated repair.

For foreign equipment:

They are mainly using the following three methods:

Firstly by way of little bit sized tooth tyre and big tooth ring; secondly central promotional mode, that is to say, the motor drives the prolongation part of the hollow shaft neck by way of the speed lower, and the last but not the least, the rotator is directly installed onto the prolongation part of the barrel or the hollow shaft neck, the determinant is fixed onto the ground, thus forming a so-called “gearless promotion”. For the time being, the hammer crusher machine adopts super low speed synchronous motor whose rotating speed is just the same as the whole equipment so that it is suitable for devices with rate more than seventy-five hundred kw.

Too often, teams are formed merely by gathering some people together and then hoping that those people somehow find a way to work together. Teams are most effective when carefully designed. For this reason, on 8th April 2010, a vibrant spring day, Henan Hongxing Mining Machinery CO.,Ltd organized an internal training activity. In the multi-purpose function room of company headquarter located in Zhengzhou city, the trainees from all departments learned attentively, discussed with each other and studied from each other. We tried our best to combine listening and learning, integrate study and application.

As an old saying goes, 'The whole year's work depends on a good start in spring.' So always plan your year in spring and your day at dawn.

The term 'reporting to one boss' can be a misleading one. In a well-designed organisational structure, people reporting to one boss do often form a team. But reporting lines are frequently designed within the constraints of grading structures. Of necessity, there is often a compromise between the need for traditional reporting lines, and grouping people together who are a team. In reality, team structures are often complicated, and people can be members of several teams, because a team is a group of people working together towards a common goal. So we give a complete training class about our product such as ball mill and other China professional jaw crusher.

As much as possible, include input from other members of the organization when designing and wording these goals. Goals might be, for example, “to produce a project report that includes a project plan, schedule and budget to develop and test a complete employee performance management system within the next year.” Write these goals down for eventual communication to and discussion with all team members.

The employees collaborated with each other and learned relevant knowledge hard. Through the training, all the staff not only improved their own skills and their understanding of company administration system but also had a deeper comprehension of us Hongxing Machinery’s policy that surviving on quality hammer crusher machine and developing through science and technology and company philosophy that virtue comes ahead of business and profit comes after customers.

Throughout the 25 years’ development, Hongxing Machinery has hold to the staff training plan of cultivating ordinary staff into outstanding talents. The achievements, experience and lessons gained in in the process of company progression themselves would be great training material for us. In future training we will work harder to make every staff gain greater improvement in daily work. We have the faith that in the positive atmosphere we RedStar people are sure to build a world of our own and create new splendors.

We are in the belief of 'Unity is strength'. Baxia for our bright future!

At any times, there are unique features in the development of one thing. For business circles, the characters are more and more complex. Next, let's analyse the main features of the development of Machinery Industry.

1: The basic station

The developed countries pay much attention to the development of equipment manufacture industry, which is in the top place of the proportion, accumulation, employment and contribution and provide the important material base for the new technology, development of new products and manufacture for the equipment manufacture industry, so it is the indispensable strategic industry of the modern economy. Even the industrialized countries entering information society all pay much attention to the development of machine manufacture industry.

2: Scale economy

The globalization manufacture has become the developing mainstream of the transnational companies. At the same time of regrouping and competition expansion, the big enterprises strengthen the investment and development for the operation to increase whose set capacity of system, individuation and diversification to adapt the market.

3: Imbalanced development

Taking 2003 as an example, 99% of top 500 enterprises are from North America, Asia and Europe, which shows that the three continents are in the incomparable governing place in the industry of world machine.

4: Deepening structure adjustment and change in the manufacture mode and management mode

The developed countries strengthen the industry transfer and the machine products with low adding value are arranged to be manufactured in the developing countries with potential requirements. To meet the change of market requirement, big manufacturers adopt professional manufacture and single product with large quantity becomes the new characteristic of the manufacture mode among top 500 enterprises and at the same time, the traditional manufacture mode is changing to the customer-oriented. The individuation of service is the main factor for the competition.

5: The new change of the mode in the industry of machine manufacture

There are two kinds of traditional globalizations: one is to regard own country as the manufacture base and sell products to other countries and the other is to invest and build manufacture base in other countries and manufacture there and sell products to own country or other countries. The characteristics are: to own the manufacture facilities and technology and manufacture products by self and for using the resources, only to use the raw materials, personnel and fun from host countries.

With the development of information technology, the management mode changed fundamentally and the organization mode changed accordingly. These changes happened in the transnational companies and will keep on developing as a new mode of globalization. The characteristic of this change is to widely use other countries’ manufacture facilities and technology strength to manufacture products and sell to all over the world. The companies of machine manufacture industry set up processing network of parts all over the world and take charge of the installation and marketing of the products. The preparation of raw material and globalization of parts become the developing trend for the world machine manufacture industry.

6: The transnational purchase in the machine manufacture industry is intense

The modern purchase doesn’t only lay emphasis on the competition and association of strong companies is the main method to gain competitive advantages, which is the big character for the machine manufacture industry to gain development. Now the market competition is intense and invest for building factory is in big risk, so many enterprises choose the combination and purchase. On the premise of building factory, to optimize the product structure to increase throughput, expand market share and gain scale efficiency is the best way. The industries with high technology have the threat from technology innovation, so only by the association, can enterprises become stronger. The strategic purchase in the machine manufacture industry leads to the new deployment of the resources and the cooperative situation of the competition appears.

7: Products with high technology

The development of modern science and technology with the information technology puts forward higher and new requirements for the machine manufacture industry. All the countries and areas and especially the developed countries lay emphasis on the development of machine manufacture, which shows that as the high and new industry, the machine manufacture industry plays an important and indispensable role in promoting the social technology progress and industry upgrade. The fast development of the high and new technology plays the role of driving, upgrade and alternation. The achievements of high and new technology, such as information equipment technology, industry automatization technology, digital-control process technology, robot technology, advanced electricity technology, electron and electric power technology, new material technology and environmental protection technology are widely used in the machine industry and the technology content is the key for the market competition.

At present, our country magnetic separation machinery manufacturer a lot, to make the product variety, specifications complex, the classification methods are also different. Although various magnetic separation machine has a different program difference, but according to the magnetic YangJiang degree, produce a magnetic field method, structure, choose different role don't, magnetic separation machine into a variety. Magnetic separator machine is use of various minerals than the coefficient of different magnetization, and by the magnetic mechanical force will magnetic mineral and the magnetic mineral separated machinery.

In the 1950 s in China only weak magnetic field magnetic separation machine belt type and tube type electromagnetic magnetic separation machine. Until 1965, just from Sweden Sarah company introduces the cavitation permanent magnet magnetic separation machine, and counterfeit, because it save electricity and magnetic induction high strength, simple structure, low cost, easy operation and maintenance, machine quality is light, cover an area of an area small, processing capacity, so fast in China in application, all replaced the electromagnetic magnetic separation machine. At present, our country magnetite concentrator use wet weak magnetic field intensity magnetic separation machine are permanent magnet tube type magnetic separation machine, using magnetic pulley and magnetic force to take off the cistern, also is the permanent magnet, realized the weak magnetic field of magnetic separation equipment and magnetized. By the 1980 s, permanent magnetic separation machine and get the cavitation fast development, not only the specifications varieties, and to the large-scale development, up to 1500 mm in diameter, tube has reached 4000 mm long, and on the structure and do improvement. At the same time, start to take new high performance materials of rare earth permanent magnet nd-fe-b magnetic materials, improve the magnetic induction strength, improve equipment performance, expanded the scope of application, in recent years, its application to obtain the further promotion, not only use it in manufacturing field magnetic separation machine, and successfully developed several strong magnetic field intensity magnetic separation machine.

The magnetic separation equipment level of technology has advanced international level, some already meets or exceeds international advanced level, in short in the world is advanced. Now in addition to the superconducting magnetic separation equipment, China's development, production of magnetic separation equipment has a leading position in the world.

In selecting a magnetic separation equipment, mainly is based on magnetic minerals and feed size to determine, such as strong magnetic minerals: grain size of 10-360 mm, choose magnetic pulley; Grain size of 6-0 mm, choose permanent magnet type magnetic separation machine; Weak magnetic minerals; Grain size of 7 to 14 mm, selection of roller of strong magnetic separation machine; Grain size in order to 5 mm, but according to ore properties choose ring type, roller type or disc strong magnetic separation machine; Grain size of 0.15 mm, can choose the high gradient magnetic separation machine.

There is something very basic about manufacturing – value is added by taking raw materials and labor, and producing products that can be sold in high quantities, with quality, to generate good return on the investment.

The manufacturing sector remains significant in leading economies worldwide, but faces major issues such as cost competitiveness, product innovation and how to compete in an increasingly global market. That people live and work in peace and contentment can not be realized without a country’s prosperity, a nation’s prosperity and people’s strength can not come true without economic development and economic advancement can not go without development of science and technology, and it will promotes macroeconomic development through penetration and influence of production factors. As we all know that productivity includes labor means, labor object and worker which are all indispensible.

Of course, innovative design and product development are important to generate competitive advantage. But design and development can be done in locations that are not necessarily tied to the production plant. Intel, for example, builds semiconductor fabrication plants in many different worldwide locations. Likewise, many automation companies build products wherever it suits their business needs. Hongxing Machinery as the leading manufacturer of jaw crusher and China professional sand maker will certainly not lose its stand.

During the past decade or so, it seems clear that manufacturing is tending to migrate away from the U.S. for a variety of factors, not the least being that manufacturing appears to have a negative image. PLC inventor, technology guru and author Dick Morley suggests that the idea that manufacturing rotary kiln is somehow bad has caused jobs to be driven out. He suggests that no community in North America really wants a new assembly plant, a printed board facility or a semiconductor enterprise. In television dramas the villain is the businessman, and the hero is the scrubby squatter who fights to prevent progress.

In modern economy, with the incessant growth of economic level, more and more industries develop into groups, among which metallurgy, machinery processing business, coal crushing and sand maker, chemistry and mining industry significantly drive the adjustment of industrial structure. So science and technology is the sufficient and necessary condition of economic development and economic improvement will not be possible without it.

In a recent survey of Chinese and U.S. manufacturers by Industry Week, 54% of Chinese companies cited innovation as one of their top objectives, while only 26% of U.S. respondents did. Chinese companies spend more on worker training and enterprise-management software. And 91% of U.S. plants are more than a decade old, vs. 54% in China.

At present, the Chinese government holds about 10% of outstanding U.S. Treasury securities, second only to Japan. Most people feel that the Yuan is undervalued by about 30% and a revaluation will devalue China's U.S. debt by a third. Unless it simply accepts a devaluation of this huge debt, China will surely be using this cash to do a lot more deals in the U.S.

As we all know, crushing of material is a technical process that is widely used in the industry departments like metallurgy, mining, construction, chemistry, electricity and road construction. Through many years’s practice and conclusion and the purpose principle of crushing and grinding, it shows that strengthening the crushing and trying to decreasing the feeding size is the important method of improving the grinding efficiency and reducing the ore dressing cost. For this reason, reducing the cost and increasing economic profit is the starting point and the crusher has been developing in the direction of fine breaking and high efficiency and low energy consumption. In addition, with the constant development of science and technology, the size of mining exploitation is becoming larger and larger and the breaker is also developing more and more large-sized.

As an old saying goes, “first-class enterprise focus on brand, second-class on market, and third-class on product”. Quality brand can bring good public praise in the industry. In recent years, brand awareness of Chinese engineering machinery users has been improving sharply. So when a brand is accepted by the customers and printed into their heart, then its place is difficult to be superseded. As for mining equipment band, in order to take up the market, it firstly should take up some place in the heart of the customers, and one key is band improvement. The existing commonly-used crushers include impact crusher and cone crusher.

We can see from the above two phenomena, if a company wants to enjoy popular support, he should firstly analyze the client’s need and find the product development direction and secondly should improve product and service quality and build his own independent band. Building a branding is building the image of the enterprise and make this image take root in users’heart. In this way, when the competition becomes fierce, the big band that is accepted by the users will survive even without fighting.

The superficial sales is just simply selling several products, but the high level of selling is to promote his own brand. Only by popularizing his own brand can he win over ceaseless clients.

Hongxing Machinery is just a kind of such mining machinery company that regards quality as life and has built internationally famous brand like ore benefication machine. Here in our company, the customers are the God, and we always follow the quality principle that we hold responsible for every production process and for every client. Everything that we are now doing is for your consideration because we are deeply convinced that quality is the gold key to market.

According to the industry policy that our country will give significant support to the development of basic industry like energy, transportation and raw material, as the backbone of these basic industries, mining machinery should get prior support so that it can further develop and improve in order to provide more crushing and grinding machines with international advanced level for the exploitation of coal, metal and non-metal mining hill, and satisfy the demand of energy and raw material of national economic development. The mining equipment mainly includes jaw crusher, sand maker and powder-grinding machine, among which crusher is the most important link in the whole rock crushing process and also the important symbol of measuring the strength of the mining facilities manufacturing industry.

Mining breaking and grinding machinery is devices that have high technology content and integration and the development of new equipment is mixed together with more and more achievements from other business scopes. With the development and advancement of material science, information technology and computer technology, every round of products are injected with new techniques, the update cycle of spare part is becoming shorter and shorter and the upgrading of new equipment is becoming faster and faster. Especially for the development of large-sized mining equipment, because there is no mature experience that can be learned and any mistake is allowed, it has to be researched with the help of mixing with many discipline techniques, improve the design efficiency and quality and enhance the company’s independent innovation ability and market competitiveness. The rock crushing and grinding devices has formed a trend of digital development with the basis of computer and internet technology.

When we look back on the development history of crusher, we can conclude that the main breakers are vertical impact crusher, hammer breaker and so on. Since the types are too many, their names are different.

The impact crushing machine developed by Henan Hongxing Mining Machinery is the example that perfectly combined with professional breaking technology and engineering manufacture and also the sufficient representation of new technique and processing method. It not only can provide the best rock aggregate for the highway, railway, high building, municipal works, hydroelectric dam construction, port and wharf and concrete mixing station, but becomes the core equipment in the artificial sand making industry and stone transformation scope, and more and more becomes the mainstream machine in the business scope of metal rock breaking, quartz sand production and slag disposal. So this series of products are well received by customers from home and abroad at the same time.

Conveyor, also named as transmitter, is a rubber and fiber and metal combination product that is used for loading and conveying materials. It is widely applied for transporting various kinds of solid material and powder materials. Conveyor can continuous, high efficiency, big obliquity transportation, and the safe operation, easy to use, easy maintenance, low freight and shortened the distance transportation, reduce the construction cost, save manpower. The daily use of the more is to pay attention to press a regulation strictly operation, and the daily maintenance are mainly used for the protection of the environment and the hardware to prevent the destruction of the system software. Programmable logic controller is functions of the logic control. It will come from all kinds of sports and function of the conveyor instruction in logical order, so they can accurately, coordination and orderly safety operation. In the meantime, it can send many kinds of information from the tools and working state to the transmitter and timely and exactly give further control order, in which way the control of the whole belt conveyor can be realized.

Speed by container in central usually main shaft and the speed of the motor machine to complete. It will motor speed matching into actual voltage value back to servo drive system as speed feedback signal, and instruction speed compared voltage value, so as to realize the precise control of the speed. Zhengzhou red star machinery factory specializing in the production of drum dryer, sand the dryer, drum dryer, sand drying apparatus mine machine equipment, the company relies on a strong research and development and production strength, has become one of the few domestic crushing, system of mechanical sand export base. Here should pay attention to the non-timing feedback voltage matching connection, and do not remove speed measuring machine. The cause of the speed control are due at the non-timing feedback line or break line be caused by. The central position of the earlier machine tool use linear or circular synchronous sensors or rotating transformer, and modern machine tools themselves

With grating feet and digital pulse coder as position central components, they coordinate transformation of machine tool in the operation of the actual position directly or indirectly central, will be the central values to Henan vibrating screen and feedback with instruction compared to coordinate the displacement until instruction position, so as to achieve precise control of the position. Position loop possible fault for more hardware failure, such as position central components to be contaminated, wire connection problem and so on.

At present, there are more than forty companies that are manufacturing vertical drying machine. When choosing such a device, many customers only pay attention to its superior characteristics but not give attention to its limits, because any kind of machinery has it own application scope but nor all-purpose applicable. For this reason, many problems occurred in its using process, and to make things worse, some equipment is idled even after using for several months.

1. First problem is very common, that is when purchasing, and the specifications of the dyer machine is too small. In a cement plant in Sichuan Province, the company purchased from a manufacturer, the production company said that the production capacity can reach twenty tons every hour, but in actual use, the output ability is only fifteen tons for each hour. When we look into the reasons, we find that the manufacturing enterprise purposely decrease the specifications with the view of successfully doing the business with low prices which in the end brings loss to the using corporation.

2. Material baking is not stem, yield of not to come. Material baking not stem, in drying slag moisture content is lesser, the effect is good, if baked some, such as clay, fly ash, etc material especially prominent. A cement plant in Yunnan choose a company a φ 2.2 * 14 in the purchase, production manufacturer when baked clay speak up to 15 tons /, the actual production of only 5 tons /, the contrast is bigger. Investigate its reason:

(1) moisture content really is on the high side, stay time enough;

(2) the drying system equipment is not reasonable, can not be education moisture;

(3) manufacturers can't master good drying original parameters.

PF series impact crusher is widely used in various metallic and nonmetallic ores, cement, abrasive material, glass, construction material, machine-made sand, metallurgy, etc. Impact crusher is also applicable to crush various stones with different hardness in medium and fine crushing area, such as used in iron ore crushing plant, non ferrous metal, emery, bauxite, quartz sand, basalt, etc. PF series impact crusher for sale is usually used in secondary crushing processing, subsequent the primary crusher-jaw crusher.

Since ground minerals are the major raw-materials used in various items like ceramic industries, Chemical, Metallurgical industries etc, the industrial demand of these products is ever increasing all over the country. Despite the fact that there are many registered and non-registered units operating in the country, there is enough scope to later the need of industrial sector. Reportedly, these are so many supplier’s traders and agents who supply the ground minerals to the existing industries from outside the state. Hence a stiff market competition in this sector is never ruled out. But maintenance of customer’s specification to their satisfaction uniform quality, supply schedules and payment terms are the key to open vast marketing opportunities for new unit in this field.

In mine machinery,Many criteria need to be considered in selecting the appropriate equipment for a particular mining operation. The most important factors to consider are safety, strength and durability, though cost can be a major aspect.

There is a vast range of mining equipment available, dependent on the application for which it is to be used. Underground mining, surface mining and open pit mining all require the initial movement of large quantities of earth. This equipment is similar to that used in large building projects, in the form of dump or haul trucks, diggers or shovels, back hoes and cranes. The extraction of ore requires a different collection of mining apparatus. Ore crushers, explosives, separators and other devices complete the full complement of necessary mining equipment. It is vital to remember that personnel are the fundamental aspect of any mining operation and their safety is paramount. Essential mining equipment must also include safety supplies, such as hard hats, ear defenders and respirators, to prevent employees form injuring themselves (or each other) whilst working in hazardous conditions.

Heavy duty earth moving equipment can be bought direct from specialist manufacturers who focus on loaders, trucks, drills and scrapers. Other companies offer leased rebuilt / used mining equipment by major manufacturers. Many mining equipment manufacturers make ore extraction equipment. Some specialise in air compressors concentrators and tunnel boring machines, whist others produce conveyors, crushing plants and hoppers. Specialist underground mining equipment manufacturers offer an extensive range of pallet handles, tow tractors, belt drives, radial stackers and power packs. Several manufacturers produce a range of health and safety products. Some specialise in respirators, hearing protection, gas detectors, fall protection devices, hard hats and goggles, while others offer an assortment of specialised flags and lights for use inside mines, along with rescue equipment for both underground and surface mines.

A mining undertaking can often be large and complex. In order to ensure a project progresses efficiently, safely and is completed in a timely fashion, sufficient supplies and equipment must be made constantly available. For speedy service and extensive choice of products, the Internet is an excellent choice for the purchase of mining equipment. Many mining equipment manufacturers and distributors have detailed specifications and photos of their inventory on their websites and there should be few problems in locating the appropriate tools and equipment for any mining project. New equipment can be bought directly from its manufacturer, though it can be a good money saving exercise to peruse the used and / or refurbished equipment offered by many manufacturers. Other firms specialise in the hire of mining equipment and dependent on the available capital, this may be a preferable option to outright purchase.

A shortage of qualified workers for the mining industry has the Iron Mining Association of Minnesota worried.

Duluth, MN - (Northland's NewsCenter) - The growing Northland mining industry, in conjunction with an impending flurry of baby boomer retirements, is creating a significant worker shortage.

Industry spokespeople say they're concerned about the Range finding the thousands of qualified technical workers it's expected to need over the next few years.

'Almost 40-percent of the people working in the mines can retire at this time...so we actually have a work force shortage,' says President of the Iron Mining Association of Minnesota, Craig Pagel.

One of the biggest problems is finding enough qualified applicants for the positions.

'You might find one out of 40 qualified. You might have a couple of job openings and over 400-people will apply and it gets weeded out pretty quickly because they do not one have the job set skills that they need, they might not have the education that they need,' Pagel says.

As the mining industry evolves on the Iron Range, employers are demanding more from job candidates.

'They're really struggling to find hundreds of people that have very specialized training,' says Regional Labor Analyst for DEED, Drew Digby.

Years ago a high school graduate could get a job working in the mines...but not these days.

Currently a qualified mine worker needs to have at minimum of a two year degree.

'What we're finding is, many cannot pass an 8Th grade reading comprehension, they can't pass 8Th grade math skills sets...but more importantly is attitude and the fact that many of them cannot pass the background checks and drug tests...it's a real concern,' Pagel said.

'One of the things you keep hearing from the mines is they want someone who has all those great, old school technical abilities, they ability to work with things and get your hands dirty, but also handle really specialized equipment...some things with a lot of computer assistance,' Digby says.

The Iron Mining Association has been working with the Northeast Minnesota higher education and state lawmakers to develop curriculum's for high school juniors and seniors so they can get college credit even before going to university and have a better understanding of what's needed to be a modern mine worker.

'These are very good paying jobs. Some of the starting salary jobs in the mine's, on an hourly type of job is 26-dollars an hour, plus benefits,' Pagel said.

An attractive annual salary of around 54-thousand dollars a year.

Pagel said there are about 175 service sectors that belong to the IMA, along with the mines, that supply products and services on a daily basis, who are also concerned about the lack of a qualified workforce.

Minister of Land and Resources recently held China International mining Conference, said China is committed to scientific development, continue to adhere to save low resources consumption, little environmental pollution and the new road to industrialization. 'scientific development, promote green mining' is a new path of industrialization in China mineral resources in the field of concrete embodiment. Here, the green mining industry has become the most eye-catching words, the reason for it visible, because it is China's economic development, because it is in line with the direction that mining industry calls for the requirements of energy conservation advocacy and environmental protection development.

The so-called 'green mining' refers to the disturbance in the mine environment is less than the premise of the capacity of the regional environment to achieve optimal exploitation of mineral resources and the environment are minimized. Implementation of green mining industry there are three stages: First, the regional environment through the development of capacity or former capacity evaluation and mine environmental assessment and disturbance, the establishment of environmental evaluation index system and technical standards, to develop green mining plan; but through technological innovation, optimize Process, to achieve mining, dressing, smelting and refining process, a small disturbance, no poison and less pollution; Third, through the mining environmental management and ecological restoration, to achieve minimum environmental disturbance and ecological reconstruction optimization. We say that the development of green mining is the voice of the times, China's economic development, it is not groundless, but evidence-based. Over the years, our economy has been growing rapidly though, but we also paid a high price, called a lot of fees. Relevant data show that the country due to ground subsidence due to mining to 180 locations with more than 1,600 pit collapse, subsidence area of over 1150 square kilometers. The collapse of the national mining subsidence disaster occurred nearly 40 cities, causing serious damage to the 25 annual ground subsidence due to mining, the loss occurred up to 4 billion. The mining, ore mining 6 billion tons per year the amount of disturbance of the Earth's environment, induced the mountain crack, collapse, landslide, debris flow, earthquake and other geological disasters. These figures are shocking, but in order to change this situation, to promote green mining industry is the best way.

China's hydraulic mining machinery industry and the world advanced countries there is a gap, and the gap is our great progress space, in order to be able to reach the world advanced level, only recognize the difference, the gap from place to start, and constantly improve their standards in order to continuously improve our ability of hydraulic mining machinery. Let us first analyse our country and the advanced countries in the world in hydraulic mining machinery industry gaps.

Hydraulic network of excellence senior consultant hydraulic Li Gong from the current point of view, the domestic mining industry science and technology foundation is thick, and the field of the mining machinery has been change a technology with the market as a way to improve the level of product technology is not phase, and to face the foreign competitors, especially the foreign competitors in the domestic investment and set up factories in the grim situation. Therefore, the domestic mining machinery enterprise innovation consciousness forced excitation.

Domestic major mining machinery R & D and exporters in Shenzhen city of God extension mechanical and electrical equipment limited, enterprises in the face of domestic and foreign innovation competition of enterprises, after years of rapid adjustment, now Shanghai state of the world has been established, complement and perfect the advantage domain application research and development base, launched to crusher, milling machine and system sand machine as the main products, manufacturing process and process technology application research. Shanghai world Bang after the pioneering and innovative ways, practice, research and development of new products, to meet the mineral resources of mining machinery made more specific, more explicit content of innovation, in recent years the company's R & D results: tracked mobile crusher station, a mobile mobile crusher station, PFW European version of deep cavity hydraulic crusher, JC the European version of jaw crusher, cone crusher, CS HPC hydraulic cone crusher, sand making machine, the new VSI VSI5X centrifugal impact crusher, V.W high grade stone shaping machine, MTW Euro trapezium mill, LM large vertical milling machine, SCM superfine milling machines and other equipment are energy saving, water saving type, comprehensive utilization, environmental protection of mining machinery products, and can give the operators to create a safe and comfortable work environment.

So, our country and international developed country the main reason of difference of existence or technical level. China in the innovation and international developed country manufacturing level is still a gap in the domestic challenges, so great. Domestic and foreign mining machinery gaps exist for many reasons, including market demand differences are caused by a gap between the objective reasons, due to the international market for excellent mining machinery manufacturers focus areas in Europe and the United States, where large-scale basic construction stage has in the past, the market for aggregate demand is not much, and environmental protection requirements are high, certainly will forms gravel field height focus on large-scale production to achieve environmental protection, they required mining machinery specifications, strong maneuverability, high automation process think. To meet the market demand for the development of the mining machinery and domestic product is not the same as, as we are at the large scale infrastructure throughout the period, the demand for mineral resources mineral resources increase, investment caused by heat, blossom everywhere mines are often small in scale, but started fast, less investment, the market demand so crudely made, technology level is low, energy consumption high, serious environmental pollution products have entered, but these devices are often only at low prices to capture the market, so with the international advanced level difference.
