Whenever establishing the property value of equipment, whether or not for farm equipment, manufacturer equipment, restaurant equipment appraisal or machinery appraisal, the appraisal business will need to take on one of three methods. The actual method to be used depends upon readily available data, the condition of the machinery and the business asset which is getting the appraisal.

The 3 old-fashioned strategies to establish the property value of anything are: Cost Approach; Sales Approach; Sales Comparison Approach.

The Cost Approach compares the price tag to restore the machinery or equipment then taking away the level of wear to the item. This method considers various factors; what was the price of the machinery when bought new from the factory, precisely what the valuation on the particular equipment is these days if purchased new and also the estimated expense to refurbish the machine to be regarded as totally refurbished.

The Sales Approach is also known as the Market Approach. The Sales Approach may be the more widely known strategy to appraising machinery and equipment. Real Estate appraisers make use of this method to establish value on a household. The Sales Approach works very well for machinery appraisals because marketplace info is readily obtainable and also reliable.

The Sales Comparison Approach to valuation compares the sales of other equivalent machinery or equipment within equipment auctions, classified prices and other known marketplace valuations. Using the knowledge of the market industry the appraisal company is likely to make adjustments to the worth of the machinery that indicate the equipments age and condition.

To determine replacement prices the appraiser will most likely choose the manufacture and other prices lists. The actual replacement price is the cost to replace the equipment completely.

Devaluation aspects can be determined by just how much wear and tear the equipment has on it, as well as by obsolescence. Devaluation variables also are influenced by life expectancy, its age, and also the equipments functional status or utility. Some other depreciation variables will be affected through things such as regulatory concerns, monetary penalties, as well as supply and demand.

Yet another approach that is less frequently utilized is the Income Approach. The Income Approach calculates the amount of cash flow that a piece of machinery could very well generate if totally functional. These statistics can be extremely hard to exactly figure out because possible revenues vary so significantly.

Most equipment appraisal companies use a mix of all these techniques to decide equipment value. With the use of a number of techniques the professional appraiser is able to help support the valuation of the equipment they are appraising.

As many things are going very fast in today's changing world. So, we have to be prepared for all those changes. Technology is one of those things which is going a rapid change from a few couple of years. People are becoming familiar with the machines. Different types of machines are used by different groups for different purpose. Here, we will make discussions about steel rolling mill machinery.

This machine is used in factories for preparing metal sheets. Before moving ahead, you must know what metal is? Well metal is an electropositive element having shiny surface and is good conductors of heat and electricity and can be melted or fused into any shape you want by heating it on a high temperature. Metal sheets are made by passing the material between the rollers. It is used for different purposes such as nail making, metal or steel sheets. This machine is categorized into two parts: hot rolling mill and cold rolling mill.

If the temperature of the metal is above than its recrystallization temperature then it is termed as hot rolling process. If the temperature of the metal is below than its recrystallization temperature then it is termed as cool rolling process. In hot rolling mill, a large piece of metal is heated above their temperature and then deformed between rollers. Cold steel rolling mill machinery can be used for all types of heavy mechanical engineering equipments.

Rolling process is one of different types which include flat rolling, foil rolling, ring rolling, roll bending, roll forming, and profile rolling, etc. Flat rolling is a process in which a material having a rectangular cross section is fed between the rollers which results in metal sheets. Float rolling process is used for producing foils. In this process, rolling is done by cluster mill because small thickness requires a small diameter rolls. Ring rolling process is a special type of process that increases the diameter of the ring. Roll bending process produces cylindrical shaped products. Roll forming process is used for producing mechanical parts with long length or heavy quantity. There are many other methods of making metal sheets and other metallic instruments with the help of steel rolling mill machine.

When people come across the phrase ‘machinery used', they think that someone is offering redundant machinery. Many people also believe that such machinery can lead to wastage of money. Lately, things have begun to change. Nowadays, people have started investing their money in used items. People now realize that they can actually save some hard-earned money by buying used items.

Furthermore, this trend has caused a stir. Some experts claim that such items are useless. On the other hand, many seasoned businessmen say that opting for used machinery is a good idea. If you've decided to buy any such machine, you should definitely take care of the following factors:

Options – If you come across an advertisement that says ‘Machinery Used', please cross-check the details of the machinery before buying it. You must take a closer look at the options. Some of the machines that are commonly available include fabrication equipment, chip making machinery and support equipment. However, other options might be available too. Therefore, if you are looking for air compressors, manual lathes or other such items, this can be prove to be a really good opportunity for you.

Genuineness – This factor is very critical. You must check the genuineness of the item that you are about to purchase. Supposedly, you are buying an item that belongs to a specific brand, you should definitely check if that item is original or not. Used machinery equipment would only serve its purpose if it is genuine.

Price – Of course, this is the most important factor. If some middlemen are involved, you will get the machinery at a higher price. Do make sure that you check the price beforehand. This would help you in taking an informed decision.

Condition – At times, you might find such options that are really pathetic. Needless to say, you should avoid such options. Therefore, it is very important that you check the condition of the item that has been put up for sale. Talk to a professional, if you feel that you are not capable enough to determine the quality on your own.

Credentials of the vendor – Whether you buy the machinery from an online vendor or a typical brick and mortar shop, you must obtain the necessary information. It is preferable to contact a trustworthy vendor.

European stocks rose for a fourth day, with the Stoxx Europe 600 Index headed for its highest close since August, as a report showed that manufacturing in the U.S. expanded in December at the fastest pace in six months.

BHP Billiton Ltd. and Rio Tinto Group jumped at least 6 percent, leading gains by commodity producers as copper increased in London. Automakers rallied as R.L. Polk & Co. said the number of cars and light trucks sold globally will grow 6.7 percent this year. Marks & Spencer Group Plc advanced 1.7 percent as Bank of America Corp. upgraded the stock.

The benchmark Stoxx 600 rose 1.3 percent to 250.25 at 3:47 p.m. in London, heading for its highest close since Aug. 3. The gauge has risen for four days, its longest winning streak since November. The U.K., the U.S. and Swiss markets were closed for a holiday yesterday.

'The new year has bearish expectations for growth baked in, providing an equity-buying opportunity for investors as growth improves later in the year,' said Daniel Weston, a portfolio adviser at Schroeder Equities GmbH in Munich. 'The market will focus on improving growth increasing profits, low interest rates benefiting businesses and investors will see equity as a more attractive alternative than holding cash.'

The Stoxx 600 rallied 1.1 percent yesterday as a measure of German manufacturing beat estimates. The gauge posted its first yearly decline since 2008 last year as U.S. leaders wrangled over cutting the deficit and euro-area policy makers remained divided on their response to the sovereign-debt crisis.

European Budget Rules

National leaders have pledged to draft a stricter rulebook for controlling government spending. German Chancellor Angela Merkel and French President Nicolas Sarkozy will meet in Berlin on Jan. 9 to work out the details.

The Institute for Supply Management's factory index rose to 53.9 last month from 52.7 in November. That beat the median projection of 63 economists surveyed by Bloomberg News before the report. Fifty is the dividing line between growth and contraction. Construction spending in the world's largest economy increased in November, another report today showed.

A separate report on Jan. 6 will probably show that hiring in the U.S. accelerated in December for a second month, a sign that the country's improving labor market will bolster consumer spending in early 2012, economists said. Payrolls climbed by 150,000 workers after rising 120,000 in November, according to the median forecast of 62 economists in a Bloomberg News survey before the Labor Department release on Jan. 6.

'U.S. data has continued to impress and markets are expecting the trend to persist,' Jim Reid, a strategist at Deutsche Bank AG in London, wrote in a research note today.

European Debt Sales

France sold 84-, 161- and 315-day treasury bills today. The 10-year yield increased four basis points to 3.28 percent as of 2:05 p.m. London time, rising for a fifth consecutive day. Two- year yields added two basis points to 0.87 percent.

German unemployment fell in December more than economists had forecast as exports of cars and machinery boomed and one of the mildest winters on record helped support jobs in construction.

'The main focus is that there will be no recession,' said Robert Halver, head of research at Baader Bank AG in Frankfurt. 'It can be a good year for equities under the condition that European politicians do their homework. The European Central Bank is in the driving seat.'

National benchmark indexes advanced in 16 of the 18 western-European markets. Germany's DAX Index added 1.4 percent, while the U.K.'s FTSE 100 Index climbed 2 percent. France's CAC 40 Index gained 0.1 percent.

BHP Billiton, the world's biggest mining company, surged 6.2 percent to 1,993.5 pence, while Rio Tinto, the second- largest, soared 6 percent to 3,313 pence. Copper, tin and zinc advanced on the London Metal Exchange.

Crushing and grinding of ore beneficiation is prepared before the operation. Beneficiation is a prerequisite to make a useful minerals in the ore reached monomer separation.

As useful minerals to the single particle size is very small, it is sometimes necessary to ground ore will be less than 0.074 mm accounted for 80 per cent of the fine, and even some small way to achieve some useful minerals monomer Separation.

From stope ore block by the great degree, such as open-pit mining for ore block of up to about 1000 mm, 1000 mm to large pieces of broken pieces to the mine only a few dozen microns (1 micron = 1 / 1000 mm), fine-grained, often have to be completed in several stages.

To broken, in the large-scale plant the general election coarse, medium and fine three broken (also adopted four paragraphs), the lump ore gradually reduced to the size of 8-25 mm around, and then sent to the abrasive grinding machine . Until useful mineral particles to achieve separation of the monomers.

At present, the ore crushing and grinding method primarily with the role of institutions of the more common mechanical force generally have the following five.

1. Crushed by two broken face when approaching the squeeze pressure and make the materials broken.

2. Split broken teeth wedge tip is to use the materials to carry out the split of the broken, and the role of the concentration of a limited fragmentation, in brittle materials to the crusher.

3. Broken materials in the face of crushing load as bear on the two points (or fulcrum) beam, a pack materials flexor surface itself broken.

4. Stripping two broken face grinding materials made in the relative movement of materials imposed shear stress, so that material rupture occurred. Of this fine-grained materials suitable for grinding.

5. Crushing impact of the use of it is broken ore. Impact of the moment is the role of the ore. For example, the counter-crushing machine is broken in the main impact.

China’s stocks fell, driving the benchmark index lower for the sixth time in seven days, on concern about a cash crunch after interbank lending rates jumped and profit growth for industrial companies slowed.

China Construction Bank Corp. and China Minsheng Banking Corp. paced declines for lenders after one-month interbank borrowing costs surged the most since June. Anhui Conch Cement Co. and Sany Heavy Industry Co. dropped more than 2 percent, leading losses for industrial companies after a report showed earnings growth for the first 11 months of the year decelerated.

“Tight liquidity and slowing economic growth are key concerns for investors and that hasn’t changed,” said Wei Wei, an analyst at West China Securities Co. in Shanghai. “Stocks have room for further declines because we don’t see a reversal of fundamentals.”

The Shanghai Composite Index slid 18.97 points, or 0.9 percent, to 2,171.14 as of 10:31 a.m. local time, heading for the lowest level since March 16, 2009. The CSI 300 Index fell 0.9 percent to 2,313.82. A measure of small and medium-size companies slid 1.4 percent in Shenzhen. Hong Kong’s market is shut today, while the U.S. was closed yesterday for the Christmas holiday.

The Shanghai Composite has fallen 7 percent in December as concern about an economic slowdown overshadowed the first cut in reserve requirement ratios in three years on Nov. 30. The measure trades at a record low of 10.4 times estimated earnings, according to data compiled by Bloomberg dating back to 2006. For the year, the measure is down 23 percent after the central bank raised interest rates three times to cool inflation and exports to Europe slowed because of the region’s debt crisis.

Shibor Rate

Construction Bank, the country’s second-largest bank, fell 1.1 percent to 4.49 yuan. Minsheng Banking, the first privately owned bank, lost 0.9 percent to 5.84 yuan. Huaxia Bank Co., partly owned by Deutsche Bank AG, slid 0.7 percent to 11.10 yuan.

The Shanghai interbank offered rate, a gauge of the cash banks have on hand to lend to each other, has surged 101 basis points this month to 5.81 percent. It touched a two-month high of 5.89 percent on Dec. 22.

The jump in one-month interbank borrowing costs is adding to speculation China’s central bank will cut reserve requirements to support economic growth.

“It’s possible the PBOC will cut the reserve ratio again before the Chinese New Year,” a week-long holiday that starts Jan. 23, said Lily Wei, a fixed-income manager in Beijing at Harvest Fund Management Ltd., who manages about 11 billion yuan ($1.7 billion). “Demand for loans usually shoots up at the beginning of the year. Given GDP and other indicators signal slowing, if the PBOC really wants to boost growth, it’ll lower the reserve ratio.”

Slowing Industrial Profit

Anhui Conch, China’s biggest cement maker, dropped 2.8 percent to 15.05 yuan. Sany Heavy, the largest machinery maker, slipped 2.1 percent to 11.92 yuan. China First Heavy Industries Co., a maker of equipment used in the mining and energy industries, fell 2.5 percent to 3.10 yuan.

Net income for Chinese industrial companies increased 24.4 percent in the first 11 months of 2011 from a year earlier to 4.66 trillion yuan ($737 billion), the National Bureau of Statistics said on its website today. The pace compared with 25.3 percent gain in the first 10 months and a 27 percent rise in the first three quarters.

China will set a growth target of about 11 percent for industrial output in 2012, the same goal as was set for this year, the Ministry of Industry and Information Technology said on its website yesterday. Industrial production will probably grow 13.9 percent this year, China National Radio reported separately yesterday, citing comments by Minister Miao Wei at a conference.

Of course, China's stocks had also made some effects on Mining Machinery Industry. In new year, China government will take effective measures to control these situations.

Mining accommodation is among the things that must be secured, if you are running a mining business or activity. Mining is a process that extracts natural minerals from the depth of the earth. Most often, the mining is located on areas that are outside the city. It can be in caves, hills, mountains, or plains. Sometimes, it can be just within the city.

Regardless of the location, there should be a place or shelter where miners can take their rest and sleep. If you are involved in mining activities, it is part of your duty to stay in the area. You can only leave there once or twice a month depending on the stipulations of the contract. The accommodation must of course provide comfort and safety to miners. As it is impractical to build houses or structures for shelter, these associations or organizers resort to making use of existing resources. One of them is the shipping container. Shipping containers are made of steel, hence, they can last for almost a lifetime.

The primary purpose of containers is storage, so you can guarantee that the merchandise is safe while kept inside the container. However, since it is steel, the temperature inside it is also high especially during summer.

Shipping containers can be renovated to become a comfortable shelter. Among other things, they are used to construct apartment, studio, condominium, offices, classrooms, and even clinics. For mining accommodation, the shipping containers are perfect. Engineers or construction workers would use several containers to make several shelter rooms with kitchen and toilet.

Shipping containers are cheaper compared to the raw materials in building a structure. Also, since mining activities are not forever, it is only practical to use containers because at anytime, the mining activities will stop, and the purpose of the shelter becomes useless. The containers come in different prices, depending on the age of the containers.

They are also resilient. They can withstand the extreme weather conditions of an area. So, if the mining locations are either prone to winter or summer months, the containers are durable.

In order to make summer bearable, air conditioning systems can be installed or a portion of the containers are cut to give way to windows. Some professionals cover the entire containers with another with Styrofoam or carton materials coated with Uv protectors.

Another advantage of containers is accessibility. After a few years of using them, shipping lines are not hesitant to dispose the containers. Hence, they are easily available wherever you are. Despite the locations, these steel container vans can be transported and delivered. Whenever there are docks, containers are sure to be available.

Constructing a building or structure require cutting of trees. But, if you choose container vans as a pre-existing structure, you are helping save the environment. Hundreds of trees will be saved. Dumping them in landfills will take thousands of years before they are completely disposed of. Even then, the chemicals and rust are harmful to the environment. Using them such as for mining accommodation is a brilliant idea.

There are several forms of mining that are used to extract minerals and rocks from layers of earth and open-pit mining is one of these methods. This method uses a borrow or open pit and is most frequently used in situations where the desired rocks or minerals are located close to the earth’s surface.

A. The Structure of the Open-Pit Mine

An open-pit mine is structured in steps, often also termed “benches,” which are the pit’s vertical levels. These steps commonly range from four to sixty meters, but the size is largely dependent upon the machinery used by the mining company. The walls of the pit are called the batter, while the flat portion is called the berm or the bench.

Open-pit walls will generally be dug in a manner that minimizes any danger of rock falls or landslides in the event of poor weather conditions such as heavy rain. However, there may also be supports such as rock bolts or shotcrete used to stabilize the area for workers. In addition, many open-pit mines require water relief measures to be put in place. In some instances, bore holes may be drilled into the wall, which can also cause wall failures.

B. Hauling Rocks and Minerals from an Open-Pit Mine

All mines have to have a way to haul out the ore that is mined. Most open-pit mines have a roadbuilt at the pit’s side specifically for hauling away the ore, as well as any waste rock. This roadallows trucks to move safely beside the mining area and obtain their respective loads.

The waste is also an issue that has to be dealt with accordingly in any mining situation. In mostcases, waste rock will be placed in a waste dump, often an area close to the pit’s edge that is alsostepped in structure.

C. What is Left Behind by Open-Pit Mines?

Tailings are a telltale sign of a former mining operation. Tailings are the leftovers of ore that was processed and, if fresh, it is often found in slurry form in a settling pond or what is called a tailings dam. The water eventually evaporates and, if left unattended, may pose a hazard to wildlife and humans alike. Tailings may have high levels of toxicity because there are often sulfide minerals present in them, along with cyanide and other chemicals used in the extraction of ores and minerals.

D. The Commonality of Open Pit Mines and Their Fate

Most people refer to open-pit mines as quarries, so they are a great deal more common than onemight otherwise realize. In most areas that they exist, open pit mines are often repeatedlyenlarged to the point that the resource has been exhausted or until the mining process is nolonger economically feasible.

Once an open-pit mine is closed, there are several scenarios that may occur. Reclamation andrestoration has been a more recent issue, meaning that some companies that own open-pit minesmust take measures to restore the land prior to leaving the site. Other areas convert these miningareas into landfills, lakes or other ventures.

World countries will give priority to the development of coal open mining as the main way to increase coal production, as long as the conditions and try to achieve centralized mining, to raise productivity and reduce costs. Opencast coal mine are generally buried in the ground the environment is harsh, broken line basis generally do not create, and use their own mobile crushing station drive in any terrain conditions, can achieve the development of workplace. Mounted mobile crusher crusher (rough crushing with jaw crusher, impact crusher with the broken, with crushing cone crusher, stone crushing and shaping needs optional sand making machine), screening system, monitoring system is one that enter the job site without having to install the work immediately.

The introduction of mobile crusher station, confirmed that the current show broken machinery of digital product development, parallel, integrated and knowledge-based trend. One figure has become the core of rapid technological innovation and development. Advances in information technology, and promote no one from the current mining technology, mining technology to automate the traditional core of the automatic or remote control mining mining to advanced sensors and inspection and monitoring system, intelligent mining equipment, high-speed digital communications network, the new mining process integrated into the main technical features such as 'no man's crusher' development, mobile crushing plant into China's coal mining area.

Construction waste recycling rate is high, the use of a renewable resource. Construction waste in the waste by sorting, crushing, most can be re-used as renewable resources, such as brick, stone, concrete and other materials through the broken, can replace the sand for mortar, plaster, play concrete pads; focused on the latter to recover scrap metal smelting, metal materials can be re-made; bamboo wood waste can be used in the manufacture of artificial wood. Utilization of construction waste is to save resources and protect the ecological and effective way. So in recent years, especially in construction, building materials production, environmental protection and related industry has begun construction waste recycling, resulting in a certain economic and social benefits. Production of building materials using construction waste, but also reusable building materials, renewable, recyclable find a way out. Current use, though not very common, but its market prospect is broad.

Catering to this trend, Henan Hongxing manufactures mobile jaw crusher, mobile impact crusher, mobile crushing station and other advanced crushers to meet clients' demands and markets' needs.

Data indicated that during the second five, China mining machinery (crushers, sand making machine, industrial milling machine), construction machinery will continue to be steady growth rate of 17% growth for three reasons.

First, China's urbanization rate is 47%, which compared with 80% of urbanization in developed countries there is still much room for growth, and the country is also increasing urbanization in the implementation efforts, enough to support this part of our mining stone machinery, construction sand making machinery, construction machinery industry increased steadily.

Second, the emerging industry to become the strategic focus of China's economic development, so future high-capacity long-equipment manufacturing prospects are very bright.

Third, although China's tightening monetary policy, fiscal policy is still active, the future growth rate of fixed asset investment is still able to maintain 20% growth, such a growth rate of investment in fixed assets is calculated, the second five at the end China mining machinery, engineering machinery sales will reach 900 billion is not a problem.

China mining machinery, engineering machinery industry's rapid development over the past 10 years, thanks to national policy, but during the second five, the country's policy to enter a period of adjustment. In high-speed development, the industry actually needs some adjustment to future growth of open space, mining machinery, engineering machinery industry should seize the opportunity of adjustment during the second five, and strive to organizational innovation, innovation, and increase overseas M & A to make the future to more healthy and sustainable development.

China has become the world's construction machinery, mining machinery is the largest market, China's right to speak is very small, because China's construction machinery, mining machinery industry compared with foreign countries, there are technical standards, safety standards are not uniform and many other the bottleneck, while China's construction machinery, mining machinery industry to keep learning, to get rid of the kinds of impact the core components.

China and developed countries, there are still a large gap between China's mining machinery, engineering machinery future direction of the high-end equipment, intelligence and equipment. China in the future if they can be resolved within five to ten years of independent research and development of high-end components, then the voice in the world will be able to upgrade. China's manufacturing industry to achieve the future of information technology, technology to transform traditional manufacturing industries. If you want to break up the core components, we must strive to achieve self-development or acquisitions abroad.

China is hungry for metals, whether we’re talking copper, iron or aluminum. So is Europe…and, in fact, the rest of the industrialized world. We are seeing an insatiable building up for mining companies, whether early-stage or in production. The interest is in mining the metals in the ground.

The market action points to speculative buying of mining companies, especially those with a massive reserve of metals in the ground waiting to be developed.

Just take a look at the proposal by Cliffs Natural Resources Inc. (NYSE/CLF) to bid for Canada-based mining company Consolidated Thompson Iron Mines Limited for CAD$4.07 billion. At stake is the massive concentration of iron ore in the ground, which is used to make steel.

Another ongoing battle in the Canadian mining sector has dragged on for several months to acquire the massive but undeveloped iron-ore deposit located on the Mary River project in the Canadian territory of Nunavut, which is held by Canada-based Baffinland Iron Mines Corporation (TSX/BIM).

The battle for Baffinland Iron Mines began in September 2010 when Nunavut Iron Ore launched an initial bid of CAD$0.80 for the company. It is interesting that Nunavut Iron Ore was formed for the sole purpose of buying Baffinland Iron Mines and is backed by private U.S. equity.

The problem was that the CAD$0.80 bid was vastly under-valuating the value of the iron ore in the ground. Yes, it will cost an estimated $4.0 billion to get it out; but once this is done, analysts believe that there will be enough iron to feed Europe for years.

This is why the battle is ongoing for this junior mining company that has incredible potential. The bids have steadily risen after Europe-based steel behemoth ArcelorMittal entered into the bid. The price of Baffinland Iron Mines traded as high as CAD$1.58 on Wednesday, nearly double the initial bid price. And, by all estimates, the price required will continue to rise. ArcelorMittal has a battle chest of money available for higher bids. Nunavut Iron Ore has limited finances, but has said that it is seeking out cash-rich Chinese companies that are also hungry for iron resources to fuel the country’s massive economic engine.

Arbitragers have been trading the stock based on expected higher bids, and so far this has played out well. If you see bids like this surface and especially on smaller mining companies, then you can try to make money buying in and selling higher. Or scope out small mining companies with vast resources. These companies will drive speculative trading in 2011 , 2012 and beyond.

Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys. Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. Slag appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer. It might often be regarded as to become a combination of metal oxides and silicon dioxide.

Common components of slag include the oxides of silicon, aluminum, and magnesium, as well as sulfur, which is always present. Slag also contains phosphorous, calcium, ash, remnants of flux materials such as limestone, and remainders of chemical reactions between the metal and the furnace lining.

Slag is produced during the smelting process in several ways. Firstly, slag represents undesired impurities in the metals being smelted, which float to the top during the smelting process. Secondly, metals start to oxidize as they are smelted, and slag forms a protective crust of oxides on the top of the metal being smelted, protecting the liquid metal underneath. When the metal is smelted to satisfaction, the slag is skimmed from the top and disposed of in a slag heap to age. Aging slag is an important part of the process, as it needs to be exposed to the weather and allowed to break down slightly before it can be used.

In slag crushing process, there are many euqipment used, like jaw crusher, slag crusher, grinding mill, belt conveyor. Zhengzhou Hongxing is the popular manufacturer of all types of crushers including slag crushers in China together with grinding mills and other mining facilities. At present, our slag crushers have been sold and exported at home and abroad. For all clients, Hongxing can provide high-quality services and low quotations.

For all heavy industries, machinery and construction equipment are important in the construction and product projects. As is known to all, mining industry is the core industry in national economy and plays a very important role in China economic construction and social development. Naturally, mining equipment is also vital for mining industry. Mining machinery is used for extraction of minerals and rich selection of mechanical and other operations, mainly including exploration machinery, ore mining machinery and mineral processing machinery.

There are plenty types of mining machines in mining equipments industry. For domestic industry, it has already several mature equipments, such as exploiting equipments, mineral specification equipments, crushing equipments, grinding machines, sand making machines, sand washing machines, screening machines, mineral heading assembly, mineral loading equipments and optional equipments, etc.

Exploration machinery is mining euqipments used in the pit and drilling prospecting operations. It’s a kind of mining machinery. Pitting is excavating certain area of tunnel in deep accumulate, loose rock ore mining or , in order to understand the geological condition before mining operation. Mining machinery includes ore mining machinery and mineral processing machinery. The first mining equipment is mainly used for metal ores and nonmetal ores. By ore dressing process the processing machinery can be divided into crushing machines, grinding machines, screening machines, sorting (the sorting) machinery and mechanical dehydration.

Directing at some mining equipments company in mining market, they are on a small scale, large numbers and distributed widely with inefficient management and result in excess production capacity in domestic mining equipment industry. If things go on like this, Not only these companies can't live long but also would troubles get brought to our mining equipment industry. As China government turn energy saving and emission reduction on, weeding out low capacity will be sooner or later.

At present, because of serious environment polution, all governments advocate 'green industry' 'environmental protection'. For responding the calls, Chinese mining industry companies start various methods to make innovations, such as tailings recovery, energy recycling, new machines development for less polution such as mobile crushing station, ultra-fine grinder. With the trend, the competitives in the industry are more and more fierce.

The main products are newly-designed sand making machine, vertical shaft impact crusher, compound cone crusher, impact crusher, jaw crusher, high pressure grinding mill, vibrating feeder, vibrating screen, belt conveyor and sand washing machine, etc. Henan Hongxing Machinery Co., Ltd., the famous compay in China, has formed a complete production-chain that takes crushers and mills as the main products and vibrating screen, vibrating feeder, etc. as supplementary products.

Todays, prices of mineras ore and petroleum are in large fluctuation. And the situation is obvious.

Mining and petroleum industry are the two main industry all over the world. If one of them changes, it must affect global economy in some degree. Let's learn about the stake from research and development of the Research & Development Corporation of Newfoundland and Labrador (RDC).

'Leading-edge geoscience R&D plays a critical role in supporting mineral and petroleum exploration and development,' said the Honourable Susan Sullivan, Minister of Innovation, Trade and Rural Development. 'As Newfoundland and Labrador's mining industry continues to grow, research and development will assist in greater exploration and development. These investments, through the Research & Development Corporation, mark a positive step in increasing the potential to develop new mines and invite new high value business and technology development opportunities for Newfoundlanders and Labradorians.'

Mining is the second largest industry in Newfoundland and Labrador, employing more than 4,900 people in rural areas of the province, while oil production represents almost 27.5 per cent of Newfoundland and Labrador's nominal gross domestic product. The total value of minerals and petroleum production in 2010 was $12 billion.

'Newfoundland and Labrador is home to rich mineral resources, which offer students, faculty and industry partners tremendous opportunities to explore and discover,' said Dr. Christopher Loomis, Vice-President (Research), Memorial University of Newfoundland. 'This funding will build on Memorial's world-class expertise in geosciences and also help us forge stronger relationships with the mining and petroleum industries.'

The phenomenon appears not only for RDC, and it's appliable for China. At present, with the rising price of iron ore, China crusher industry and even the whole mining machinery industry have a great attack. Jaw crusher, impact crusher, mobile crushing plant are adjusted on prices, technologies, structures and services.

With the situation of continous technology innovations, some enterprises with strong competitive sense have aimed at domestic advanced consumers and matched product accessories. Just as the same as the situation in other countries, crushers were used in many industrial field, such as chemical industry, mining, construction, irragation works,metallurgy,coal mining, glass making etc in china and the most important applying field is cement producing, road paving and Mining, this application covers about thirty percents of the whole application of crushers.

At present, our crusher manufacturing industry has been in the rank of international production countries, and the comprehensive competence and development motivation of mining machinery industry are getting close to developed countries.

the life of the crushers itself is a problem(it seems that just for the buyer of crusher,the life of crushers is a problem,but the fact is for both seller and buyer,we hope our crushers get a life as long as possible).generally, a smaller crusher has just three to five year life,so,every five years later,we need update(or we can say buy a new one,it depends how you maintain your crushers)our crushers,the survey tells us a truth that twenty percent of crushers in china need to be updated every year,and the survey also reveals that many crushers have been used over their life-time anticipation.so,every year,the crusher market will get a wave of updates,that’s the second reason .

When the export of a product increase fourty to seventy percent,we call it a booming period of the product,then it runs into a critical period with trade friction appearing,that’s where chinese crusher producers stand in.so,we should remind our enterprises that we should keep ourselves alert on the probable trade friction.

Chinese crusher production scale has been in the top list of the world,but we still get a lot to learn,and as the increase of the export of crushers,chinese crusher producers will have face many contesters from all over the world,they still get a long way to go.

Appearance of hydraulic cone crusher and mobile crushing plant make a solid foundation for China crushers stepping into international market. The mark of 'Made in China' is outstanding at home and abroad.

Environmental issues received increasing attention during the last three decades of the 20th century, a situation that no doubt will continue as we move into the 21st century. Many rare mineral ore is disappearing with cities' rubbish. Human research and develop new technologies which is the main reason to lead rare mineral reserves down.

Reported by 'New Scientists', mineral resources is the same with petroleum, and both are renewable. There is a question 'how long do mineral resouces last to be exploited?'

Because the processes that form ores operate on geologic time scales, the most economic mineral resources are essentially nonrenewable.New deposits cannot be generated in human timescales.But, as mentioned previously, as the reserves of materials become depleted it is possible to find other sources that are more costly to exploit.Furthermore, mineral resources are not evenly distributed. Some countries are mineral-rich; some are mineral-poor. This is a particular issue for strategic mineral resources.

How long current mineral resources will last depends on consumption rates and reserve amounts. Some mineral resources will run out soon, for example global resources of Pb, Zn, and Au? will likely run out in about 30 years. U.S. resources of Pt, Ni, Co, Mn, Cr less than 1 year. Thus, continued use of scarce minerals will require discovery of new sources, increase in price to make hard-to-obtain sources more profitable, increased efficiency, conservation, or recycling, substitution of new materials, or doing without.

In order to help solve this crisis, China government propose 'sustainable development''green energy'. Almost enterprises are trying to change into 'green enterprise'. Hongxing manufacture mobile crushing station, slag crusher, tailings recovery, ultra-fine Raymond mill to save the materials and reduce the polution.

Dewatering is the removal of water from solid material or soil. Mineral dewatering is the removal of water from minerals.

Generally speaking, the ore concentrates classified have some moisture.

A. In the sandstone production line. Because in the line, many ores must be washed or classified, the final ores necessarily include more or less moisture.

B. In the ore dressing line. Whatever flotation process or magnetic process, they both is related with water:

(a)For flotation process (flotation machine), it's obvious. The water weight in ore concentrates of flotation plant is 4~5 times compared with the solid weight.

(b)Magnetic beneficiation (magnetic separator) can be divided into dry and wet ways. So, the water exists in wet beneficiation.

The reasons for mineral dehydration.

A. Transportation. If ore concentrates aren't dewatered, it will be difficult and high-cost.

B. In cold regions, ore concentrates with great moisture shows freezing phenomenon, which isn't helpful for ore concentrates transportation.

C. Not only dewatering for ore concentrates, but also for tailings. The moisture in tailings is almost above 70%. Therefore the tailings dehydration is necessary before entering into tailing warehouse.
