China and India are huge, fast growing, manufacturing countries. To continue in this vein they need huge amounts of raw materials. They are increasingly importing these to fuel their growth. In fact, China is forecast to be the world’s biggest coking coal importer by 2015. China’s and India’s increasing commodities imports are driving prices up, and that is hurting their own trade balances. It is fueling their own inflation. What can they do about it? The most obvious answer is that they will have to mine more of their own raw materials to even slow this trend down. In order to do this they will need more mining equipment. This means more business for the two biggest and best mining equipment makers -- Caterpillar Inc. (CAT) and Joy Global Inc. (JOYG). I remind readers that Caterpillar bought Bucyrus recently.

China and India are not the only expanding economies in Asia. There are 45 Asian countries whose economies are forecast to expand by 7.8%+ in 2011 and 7.7%+ in 2012. Most either import or export commodity resources. This means mining is increasing. One example is the planned expansion of the Tavan Tolgoi deposit in Mongolia (China). Current plans are for this coking coal mine to expand from 22.5 million tons per year in 2010 to 60 million tons per year in 2015. This will require more mining equipment. In another case, China’s Wuhan Iron & Steel is teaming with Indonesia’s PT Gunung Garuda to jointly invest $3B over the next five years to build steel plants in North Sumatra and South Sumatra. These will be fed by Indonesia coking coal, which means more mining equipment sales and construction equipment sales. China Power Investments is in talks with Guinea (West Africa) to develop a bauxite mine that would cost $5.8B. This could begin as soon as 2012. These are just a small number of the actual projects that are planned or in progress currently. All should bring business to mining equipment manufacturers, especially the two known worldwide as the best.

Won’t China want to give a lot of its business to Chinese companies? Yes it will, but CAT and JOYG are addressing those concerns too. Joy Global Inc. announced in July 2011 that it would acquire a 41% stake in Chinese mining equipment manufacturer International Mining Machinery Holdings Ltd. JOYG more recently followed this announcement by acquiring an additional 10.5% of the company. Caterpillar has been expanding in China for some time. In its latest announcement on Aug. 29, CAT said it will expand operations in China with a new proving ground and large wheel loader manufacturing facility (dubbed the Asia Pacific Proving Ground). The plant will produce the latest model of wheel loader that is being developed at Caterpillar’s Wuxi Research and Development Centre. CAT currently has 16 manufacturing facilities, three research and development centers, and three logistics and parts centers in China. Both CAT and JOYG are clearly going after the Chinese market in particular and the Asian markets in general -- successfully so far. CAT and JOYG are aggressive and growing quickly -- the marks of top companies.

Both of these companies have been sold off sharply during the recently downturn. However, as I have attempted to show above, their incomes depend increasingly on economies that are still growing quickly. The sell off is almost certainly overdone. A quick inspection of the financial fundamentals should verify this. There may be some weakness in the EU and possibly in the U.S., but the emerging market sales should hold up well. These are increasingly a large part of these two companies’ sales and earnings. Legging into these stocks now seems likely to help your bottom line. CAT and JOYG stocks are both currently forecast to appreciate in price by 51.3% and 43.9% within one year. When you can get strong stocks like these at a big discount, its usually a good idea to buy them. Each is down more than 24% from its recent high, and that is after bouncing upward a bit.

The easiest process used for mining gold is panning, employing a circular dish often having a small pocket at the bottom. The prospector fills the dish with gold-bearing sand or gravel, holds it within a gentle stream of water, and swirls it. The lighter areas of the gravel are gradually washed off as well as the gold particles are still nearby the center with the pan or even in the pocket.

To separate the gold in the gold ore collected in the mine tunnel, the ore was crushed with a series of gold ore crushers, for example primary jaw crusher found in preparing samples for assaying.

The first step of separate the gold from gold ore is crushing, then gold ore is crushed to be able to increase the surface area of the gold ore for greater gold recovery. Gold mining process equipment is loaded in to the primary crusher for initial sizing. The jaw crusher can break the gold ore rocks into 150mm or 6 inch, then belt conveyor will transport the crushed gold ore screening plant, which runs the gold ore through vibrating screens to size the fabric. Oversized rock is sent via conveyor to the secondary crushers. Secondary crushing includes impact crusher and cone crusher. inch diameter or smaller, lime is added to the ore to boost the effectiveness of the method solution by raising the PH. The gold ore is then conveyed for the load out bin. Trucks drive beneath the load out bin being filled with crushed ore for delivery towards the leach facility.

Because of the nature of the various types of gold ore is different from methods used by different dressing, but the commonly used re-election, flotation, amalgamation, cyanidation, and the resin slurry method in recent years, CIP adsorption, the new heap leaching of gold mining tool and equipment. For certain types of ore, of gold is often a joint process.

Re-election in the rock gold mine used widely, more as a secondary process, in the autogenous mill to recover coarse gold, flotation and cyanidation process to create favorable conditions to improve the mineral index, increased the total recovery of gold on the increased production And reduce the cost to play a positive role. About Shandong Province, more than 10 with gold plant using the re-election this process, the average total recovery can be increased by 2% to 3%, good economic efficiency of enterprises, according to incomplete statistics, the annual profit of several million dollars available. Henan, Hunan, Inner Mongolia and other provinces also achieved good results, with the main chute equipment, shaker, jigger and short-cone cyclone and so on. Most of the gold mines from our view, floating - Re Joint processes for use in the future we should vigorously promote the stage grinding stage sorting process, this can be advocated, as early as the principle of closing the dressing.

In coal fired power plant, coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.

The hot air in the coal mill will lift the coal particles out of the Raymond mill or vertical mill and into the boiler, if the coal particles are too heavy they will drop to the bottom of the coal mill too and will be grind, pulverize again.

The coal flow into the boiler is an important factor for a coal fired power plant. But in fact, it is not easy to measure the coal flow from the coal mill to the furnace. The coal flow out of the coal mill is often estimated based on the incoming coal flow.

Usually we grind coal into powder to improve the using efficiency. This way is common in Electric Power Plant. In this milling process, coal mill plays an important role.

Coal mill has many kinds, such as ball mill, raymond mill, vertical mill, ultrafine mill etc.

Ball mill is most widely used coal mill. It is suitable in the powder plant, and widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. It is divided into two rubbing way-the dry and the wet. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. The ball mill is a key equipment to grind the crushed materials after the material were broken , and carrying on the smashing again.

Vertical Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years research of mills, vertical mill is designed and manufactured based on our advanced design idea, and in combination with the european technology and the market demand. LM Vertical Roller Mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meets the requirement of clients in the high production of powder, and its main technical and economy indicator reachs the international level.

Raymond mill is the early coal mill, all the finished particles have a good uniformity of finess, with passing screen rate as high as 98%. This is what other machine can not reach.

Ultrafine grinding mill is a equipment which produces thin powder and super thin powder. It will highten pollution and noise by using deduster and muffler, which achieves environmental protection requirement.

A complete coal milling plant not only includes coal mill, but also other machines such as hammer crusher, hopper, deceleration machine, blower, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure moto and muffler.

Coal is grinded into powder in the coal mill; the fine particles will come into the cyclone collector with the airflow, and be discharged by the discharging value on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.

Hongxing coal mill is a flexible design, and coal mill or coal pulverizer can handle all grades of coal and is highly economical in terms of specific energy consumption. We can supply a turnkey project including design, install, and debug all kinds of coal grinding mill plants.

The infrastructure investment from the government stimulates the development of some downstream industries. The crusher industry mainly led by cone crushers caters to the current social development tide and will maintain a sustainable development momentum in the following days.

On the basis of the development of the crushing equipment industry, although the infrastructure investment is slow to rise, domestic urbanization process is still proceeding rapidly, and meanwhile urban traffic problems (rail transit construction) and environmental problems (sewage disposal and solid waste treatment) are attracting increasing attention from the public. Therefore, the concerns of the influence of China's future investment in infrastructure on the downstream industries will gradually transfer from the amount factor to the structural factor. With the R&D and production of hydraulic cone crusher and mobile crushing plant in Hongxing Mining Machinery, the market space of crushing equipment applied to new areas like premixed dry mortar and construction waste disposal has been broadened greatly. In terms of environmental protection and sustainable development, the development of crushing equipment like cone crusher has already opened up new situations.

From the future development potential of infrastructure construction, China's urban rail transit construction is still in its early stages. With the starting of high-speed railway projects in various regions of China, cone crushers and some other related crushing equipment are extensively applied. On the other hand, the domestic subway construction has just started to develop, so it will become another main market for the application of crushing equipment like cone crushers. Compared with other infrastructure projects, the construction of subway will maintain a relatively rapid growth in the long term. At the same time, the large-scale subway construction period will appear between 2015 and 2020. The construction cycle is evidently longer than that of other infrastructure projects. Driven by this factor, the crushing equipment industry is bound to keep a rapid growth momentum in the near future.

Domestic Heavy Industry notices that, the only standard to measure products’ quality is to research and produce, meet clients’ demands according to markets’ demands. Insisting on improving product quality and meeting client visible and invisible demands have been Chinese primary goal in Heavy industry.

Competition in Chinese heavy industry shows new trends. Facing to this trend, all companies work hard to improve methods and technology, so as to raise comprehensive competences.

In 2011, domestic heavy machinery industry keeps running highly, and the import is supposed to be 15% increase above, while export 20% increase. But it will take a long period to recover its economic status i.e. 13.42 billion US Dollars before Financial Risk.

In June 2011, the month-on-month producer price indexes for the industrial sector maintained the same level over the previous month, or it was up by 7.1 percent over the same month last year. The month-on-month purchaser price indexes for the industrial sector was 0.2 percent up while the year-on-year growth was 10.5 percent. Not only changes of mining industry in Chinese market, but also there are tough changes in South Africa.

South Africa may strengthen mining laws because companies are compromising worker safety as they accelerate production amid rising commodity prices. South Africa, where Anglo American Plc (AAL), BHP Billiton Ltd. (BHP) and AngloGold Ashanti Ltd. (ANG) operate, is the world’s largest platinum producer and Africa’s biggest gold producer. Its mines are among the world’s deepest, and labor-intensive methods have made them some of the most dangerous. About 76 people died at South African mines from Jan. 1 to Aug. 15, compared with 79 a year earlier, government data show.

The ruling African National Congress is studying nationalization of mines following calls by its youth wing. Shabangu has resisted such a move, saying it may threaten investment in the industry. “I am surprised that while globally there is real concern about the state of the world economy, with all countries chasing investments to shore up their economies in a bid to drive growth and create sustainable jobs, we are grappling with a debate about nationalization,” she said. “We have seen some of the mining investments going to other mining jurisdictions.”

Of course, it happend many times in China. So we can consider that how important to choose mining machine with good quality, high satety and advanced technology. Henan Hongxing Mining Machinery Co. specializes in Jaw crusher, Impact crusher, Combination crusher, Sand maker, Flotation machine, High-strength raymond mill and other mining machine. Its products are all in good qualification and high technology, so as to make sure all safety in mining operations, And Hongxing Brand is a “China Famous Brand” for reliable and stable quality. It firmly believes that it can get sincere repayment with our sincere dedication.

Recent years, it appears many disasters. For example, the earthquake not only in Sichuan of China in 2008, but also in Japan this year. Beijing time on March 11,Japanese waters around maizuru, Richter 9.0 magnitude earthquake.By this earthquake is influencing Japan's heavy industry such as domestic mining machinery. Japan is the important origin of global engineering machinery and the key parts. We think, after this earthquake, thread of nuclear pollution, post disaster reconstruction, inconvenience of transportation, losses of economy and other factors pulled mining machinery needs, which decreased the exports of China mining machinery to Japan.In mining machinery, there are mainly 4 series of mining equipment: stone cushing machine, sand makeing machine, powder making machine, ore dressing machine. Of course, burning-free brick machine and others are included. Nowadays, the mining market is mature, and expands so fast. The mining machinery suppliers must make revolution and improvment for future development and competition.

China’s 27 largest steel companies saw a 15.7% decrease in the first-half profits from a year earlier for a combined profit of 10 billion yuan ($1.6 billion), according to the Shanghai-based researcher Wind Info, as soaring iron ore costs squeezed margins. We must grasp every chance to make our own company expand and eventually make our country's mining machinery industry prosper.
