August 30 molybdenum concentrate prices commentary: the apparent market turnover rose slightly

August 30, 40-45% of the price of molybdenum concentrate ≥ 47% in the 1440-1450 yuan / ton, high-grade molybdenum concentrate prices in the 1450-1460 yuan / ton; of domestic molybdenum oxide prices 1540-1560 $ / metric ton. Domestic 60 ferromolybdenum price in cash 101,000 yuan / ton basic, accepted 104,000 yuan / ton. "MB" the British metal Herald, molybdenum oxide, 11.4 (0.5) -11.7 (+0.3) U.S. $ / lb, molybdenum, iron 28.5 (+0.7) -30.1 (+0.8) U.S. $ / kg, LME stocks 264.

Financial Highlights: iron and steel industry into the era of little profit in the second half or more severe; brief good die hard iron and steel enterprises secondary market vulnerable situation; of Panzhihua Coal Mine Accidents caused nine people were killed and 38 people are still trapped underground; central bank for the first time to carry out a 28-day reverse repurchase inquiry The amount; steel industry losses spread to 17 interim net profit fell sharply; the Baosteel ignite repurchase passion, the net three broken faucet favored.

The steel mill tender information is as follows: August 27, north China steel mills to move 500 tons of ferro molybdenum 95,500 / ton (50% acceptances); August 27, east of a steel mill to 9.6-9.65 million / ton (cash ) move 450 tons of ferro molybdenum; August 30, East move 80 tons of ferro-molybdenum steel mills; August 30, north China steel mills move 50 tons of ferro molybdenum.

Market turnover show of the molybdenum iron ore prices rose slightly today, businesses generally bullish on short-term market. Two working days last week, all regions molybdenum the iron molybdenum concentrate turnover general. Today, most of the steel mills bidding continues, but slightly dull upstream molybdenum concentrate market demand. Molybdenum price trend is not clear that the majority of molybdenum ironworks little demand for raw materials. Due the molybdenum iron market prices continued to rise slightly, the possibility of the ferro molybdenum late price lower and lower.

Expected: molybdenum-iron, domestic market outlook will continue to show a pattern of rose slightly, September ferro molybdenum market purchases will show a general, transactions in general, but the price is still the lack of a substantial upward momentum, the molybdenum City will continue to bear a greater pressure.

Australia's third-largest miner FMG forecast iron ore prices will crash

Australia's third-largest miner Fortescue Metals Group Ltd (FMG) chief executive Nev Power said at a business luncheon in Sydney on Thursday, short-term price of iron ore will also fell sharply. He said that iron ore prices will not rebound before the return to growth in China's iron and steel industry production.

Nev Power said: "We expect the price of iron ore will be a dramatic decline, and will then return to the price of 120 U.S. dollars / ton over the past two months, iron ore prices plummeted 33 percent, has come down to per ton the $ 90 level, the lowest price since November 2009.

Nev Power said that iron ore prices continued to fall, the company will consider other investment options. He said that, taking into account the current world economic situation and commodity market conditions, the company will no longer consider debt investment. In addition, he also ruled out the possibility of recently issued bond financing.

Nev Power said: "In the present case, liability management is unwise and dangerous."

Foreign media: Global miner worry the end of the "super-cycle"

The mining industry is facing a lot of negative factors, they are squeezing revenue, reduce cash flow and force corporate management team to make more difficult choices. Fears that the soaring demand for investment due to insufficient supply is limited, pushing up commodity prices such as copper, coal and iron ore, the so-called "super-cycle" is to come to an end.

"The bull market can not last forever"
"Bull market can not last forever," said Managing Director of Accenture Mining Rachel Bartels, "but the underlying demand for commodities will not disappear in China and India is not yet complete urbanization, Africa and even not yet started process. "

However, the challenges faced by the mining enterprises and even a year ago. Chaoda Group (Xstrata), Anglo American and Eurasian Natural Resources Corporation (ENRC), including mining companies this year to cut the growth project expenditures, many companies also promised to evaluate the plans for the future.

Six months ago, the (mining companies) like the Bulls stormed out of the gate, comparison and who want to be able to spend more money, "Deutsche Bank stock analyst Rob Clifford said," Today, they cautious. "

Miners unable to meet the cash flow in the first half of the capital expenditures and dividend payments. Debt levels in the industry is expected to continue to rise.

Clifford said the miner is entering a downturn phase, but at this time continued to maintain a strong balance sheet, expected debt will continue to increase in the second half of this year. He said: "However, slightly faster than expected."

UBS (UBS) analyst Myles Allsop said: "In the current uncertain macroeconomic environment, we expected to see that investors will favor more defensive diversified enterprise, rather than single commodity group. "

Despite the difficult road ahead, but several of the largest Mining Group by the first half of this year increased dividends, while the the poor Kazakh Copper Group diversified firms reduced dividends.

Control their own costs
Recent iron ore price collapse sparked fears of the market, Rio Tinto and Vale do Rio Doce, the two companies are highly dependent on the iron ore business. In the past three months, iron ore prices fell by about a quarter.

But analysts pointed out that the low-cost operators Rio Tinto in the Pilbara region, Western Australia, will provide protection in the case of iron ore prices fell further.

The recent mining companies a good news is that the momentum of its rapid rise in the cost of production seems to be weakening. Rising costs eroded profits and push up the cost of the development of large-scale projects of the mining enterprises. With the slowdown in input prices rising trend of oil, rubber and chemicals, Anglo American production costs in the second half of the year is expected to rise by about 2%, less than 4% in the first half of this year and 8% in 2011.

Allsop said: "slowdown due to rising raw material prices, the mining company's self-help measures come into play, we really felt that the trend of rising costs has now slowed down." He said self-help measures to staff reductions as well as shutting down The higher cost of production of the mine.

The cost of labor is also a problem, experienced engineers and operator sustained shortage. Workers in the labor market in countries such as South Africa, Australia and Kazakhstan, also require raising the level of wages. Bartels, management's ability to control costs will become increasingly important in view of future mineral prices will be under pressure. She said: "Mining Group may not be able to control their own income, but they are able to control their own costs."

The Australian mineral Feast end to finish at the introduction of mining giant contraction strategy

Australian Resources and Energy Minister Martin Ferguson has said that the mining boom has ended. The remarks immediately triggered several senior officials, including Prime Minister Gillard rebuttal, the latter insisted that far from the end of the mining boom will continue to support Australia's sustained economic growth.

As a pretext for the head, scattered around the mining prospects remarks fierce collision is the evolution of the long and short view, a reflection of the Australian mining complex variables. Despite excessive sing empty Mining may be too hasty, short factors affecting the mining industry would still be worth to think calmly.

The mining magnates introduced contraction strategy
Recently, BHP Billiton, Shell, Woodside mining giant has announced the postponement of Australia iron ore, natural gas project, involving the amount of investment so far has exceeded 68 billion Australian dollars (U.S. $ 70.4 billion). The direct cause of action in a series of contraction is the uncertainty of market trends.

Affected by the European debt crisis, slowing growth of emerging economies and other factors, the main iron ore price of about $ 180 per ton from the same period last year shock down to below $ 100 a tonne, a record low since December 2009.

Pushing Hands introduction of mining giant contraction strategy much more than lower prices. Exchange rates, tax rates, finance, and industry profit distribution structure factors can not be ignored. CLSA analyst Ian Loper said iron ore prices fell to $ 60 per ton in 2008, but then the Australian dollar against the U.S. dollar exchange rate is only 1 to 0.6, the cost is relatively low. In recent years, however, the exchange rate of the Australian dollar against the U.S. dollar exceeded 1.1 high and stable at a ratio of 0.93 or more in the past year. This means that the market price is lower, the profit margin of the miners and even less than the outbreak of the global financial crisis.

BHP Billiton CEO Marius Kloppers pointed out that over the past 10 years, the Australian mining development costs in U.S. dollar terms increased sevenfold, half of the cost increase is directly due to the Australian dollar soaring.

Australian government efforts to promote the carbon tax and mineral resources rent tax reform. Taxes to improve together with the high Australian dollar and other negative factors, will significantly increase the cost of mining development.

The research report released by the Minerals Council of Australia, Australian thermal coal cost per tonne of new capacity within the past five years rose three times, so that the relevant feasibility of the project into doubt. Compared to West Africa, 75% above the cost of iron ore mining in Australia.

In addition, some small and medium-sized mining companies must also focus on financing costs.

Disparity unfair distribution of profits of the upstream and downstream
In addition to the above factors, the Australian mining more fundamental problem is that the status quo of the current industry upstream and downstream disparity unfair distribution of profits.

For example, iron ore, according to industry sources, one ton of iron ore in Western Australia offshore cost less than $ 60, while the offshore market in recent years, the average price was as high as about $ 160, and for many years maintained a double-digit increase. Many Chinese steel enterprises but has incurred losses in miners earn pours. By the shrinking demand for steel, Steel Association member companies, losses in the first half of this year more than one-third of August, expanded to more than 80% loss. China Steel Association said China's steel industry is only 1.68 yuan (about 0.26 U.S. dollars) per production of 1 ton of steel profits.

As an important raw material base of the China Iron and Steel Industry, Western Australia more than 70% of the iron ore supply the Chinese market. In this regard, one wonders, in industry downstream face of massive industry-wide loss situation, the mining the feast what can enjoy long?

Analysts pointed out that the view of some developing countries, urbanization, industrialization process has yet to be completed, and the Australian mining investment accumulated stock of up to 270 billion Australian dollars (U.S. $ 279.6 billion), mining will continue to support the economic growth of Australia. In addition, since the financial crisis, the U.S. policy of quantitative easing fueled commodity markets may still push up the market price if the authorities to release a new round of quantitative easing.

However, if future short factors continued to exert influence each other, inevitably promote the current mining boom downhill.

Australia's central bank recently said that mining investment is expected to peak will be reached in the 2013-2014 fiscal year, and then after years of downlink non-resource sector investment will appear accordingly uplink. This may help to alleviate the current plight of Australia's two-speed economy ".

The iron ore price decline is still outside the mine ratio up to record highs

Continued downturn in the domestic steel market the moment, as the upper reaches of the iron ore market is also hard to change the tide. 61.5% grade ore imports decline than domestic ore deeper, relatively active trading Australia powder the index has Pobai, and imported ore and domestic ore spreads widening further, which also led to many steel mills outside the mine ratio reached a record high . According to the latest survey on the part of the steel mills in iron ore inventory, samples of steel mills in outer ore ratio has reached 98%.

Imported ore price index yesterday (August 28), the composite index of imported ore at the date of 104.8, down 1.60% compared to the previous day's 106.5 the previous month, 123.3 or 15.00%, or 41.45%, compared with 179 in the same period last year. On the same day, the composite index of domestic ore 136.1 and 136.5 in the previous day, a decrease of 0.29%, down 5.81% from the previous month's 144.5, down 32.39 percent compared to the same period last year 201.3.

"Recently imported domestically in the fall, but the exact look you will find more imported ore than domestic ore or Burden Division analyst said that the spread of the imported ore and domestic ore along with two by different decreases gradually widened, fell more imported ore and therefore have a more significant price advantage, coupled with a lot of steel is more serious loss, taking into account the cost factors, the price is relatively higher domestic Mine is the first to be eliminated, so many steel mills outside the mine ratio was reached a new historical high.

August 10 to 24, 55 steel mills in Tangshan, Handan, Xingtai, Shandong, Shanxi and other regional iron ore inventory statistics show that the average sample steel mills use imported ore ratio of 90%, compared to the last (July 27) statistics increased by 2%, including the highest sample steel mills outside the mine ratio reached 98%.

In addition, it is worth noting that the relatively active trading 61.5% grade Australian fine ore imports in August 27 of each sub-index index was 99.5, down one unit as compared to the previous day, which is the index in recent years first Pobai. Yesterday, the index fell another four units, 95.5. Stakeholders in the industry believe that "Despite recent price has fallen a lot, but later imported ore market is not optimistic due to the the downstream demand incompetent, the inquiry is still light in the market, the transaction is still poor, and the relatively weak competitiveness of domestic ore I am afraid that the days of tough some.

Impact crusher operation works and disadvantages

Impact crusher operation works as well as rewards and disadvantages

Impact Crusher is a highly helpful new crushing equipment.

The ore within the feed port to the entry, and slid down along the sieve, the ore for the sieve during the dropping process, i.e. the high-speed rotation for the rotor carbide hammerhead crushed inside a tangential direction, and also a pretty higher speed flying very first a counterattack board, ore go on to generally be damaged, counter plate carried the ore strike collide with each other ores thrown back again powering the rotor, so during the very first crushing chamber ore was crushed by recurring shocks. Some ore damaged during the very first crushing chamber to a specific size, after a counterattack the gap amongst the plate as well as rotor row to the second crushing chamber, go on to generally be recurring strikes till the smaller particle size after row of ore within the bottom in the crusher discharge port .

Crusher within the previously mentioned, would be the influence principle crushed ore, is represented from the adhering to two formulas:

Ore kinetic electricity received: E = 1/2MV2

Ore by influence:

F = M (V2-V1) / T

In which M - the quality of the fabric to generally be damaged, kg;

V - the rotor peripheral velocity, m / sec;

V2 - the resources block is beat speed, m / sec;

V1 - resources block was versus the speed, m / sec;

T - the job of time, in seconds.

Can be witnessed within the previously mentioned equation, inversely proportional to the the counterattack force aided by the duration of action, and lump ore is proportional to the acceleration suffered materials blocks the kinetic electricity as well as sq. in the speed in the rotor movement and excellent of resources proportional to the solution.

The most important advantage of the impact crusher:

one) uncomplicated structure, compact size, gentle body weight, large ability, minimal manufacturing expenses.

two) ore along the joint plane damaged, so considerably less electrical power consumption, higher performance.

3) damaged than large, about 40, so you can simplify the procedure damaged, might make the three-stage crushing into two sections or perhaps a damaged, reducing the cost of the concentrator equipment.

four) possessing a selective crushing outcome, as well as crushed solution of somewhat uniform particle size, shape nearly all the cube.

The biggest drawback in the impact crusher, hammer and counterattack plate have on a lot quicker.

second hand impact crusher Sand operates:

Substance within the feed hopper to the crusher, the fabric is split into two parts from the sub-feeder, among the sub-feeder to the high-speed rotation in the impeller, the impeller being speedily accelerated, acceleration of about various hundred moments the acceleration of gravity, after which within the impeller a few uniform move channel in a speed of 60-70 m / s projectile out, firstly aided by the part in the self-generated revenues falling by round the sub-feeder materials impact crusher, and aided by the influence in the vortex cavity lining resources, materials lining rebound oblique influence to the top rated in the whirl chamber, but in addition to alter its direction of movement, deflected downward movement of material emitted within the impeller form a steady resources curtain. These types of a material during the the whirl crushing cavity by two times along with various moments the chance of influence, friction and grinding crushing outcome. The damaged materials is discharged within the reduce part in the discharge opening. And form a closed cycle screening system, the a few basic circulation resources damaged into twenty mesh. Substance mutual self-impact crusher during the total crushing process, not in immediate communicate with aided by the metal factors, but aided by the lining resources shock, friction and grinding, which lessens air pollution angle, to extend some time of mechanical have on. Self-loop, the the whirl chamber inner clever airflow gets rid of dust air pollution.

Olympics used green shibang broken machine liner

Recently, reporters learned through market research, sales of sand and gravel production line equipment in the market is very hot, wear-resistant lining of the crusher may be used for the Olympic Games In particular, it is stone ground into the sand is to become a magic weapon for people to deal with natural sand diminishing this critical situation, therefore, stone sand will become a beautiful landscape in the building materials industry.
The past two years, in order to achieve the perfect ending of the "12th Five-Year Plan, the state will vigorously develop the infrastructure, but due to changing market conditions and the lack of funds, many large infrastructure projects in the state of digging to be built, which makes building materials industry has been had a great impact, especially the cement industry has been showing in the first half profit continued to decline, some of the weaker strength of the cement companies make ends meet, has been the delisting eliminated, we can say with cement-based building materials industry a red light in this year's development.
However, a fiery sand and gravel production areas to eliminate concerns about the future development of the building materials industry, the experts predict, sand and gravel production in particular, the mill liner in Shashi production gotta application development in the current, the future will be a hot market not to be underestimated, there are three reasons:
A large national projects appear broken, but some people's livelihood project continues, such as urban subway construction, new rural construction of concrete mixing plant for the production of sand and gravel aggregates of small business .
2, a single development of the cement industry no longer meet the current market environment, opening up a two-way profit point is imperative. From the national focus on environmental development and the national Ministry of Industry began in 2011 released the first batch of backward production capacity of cement companies, cement industry is aware of a structural adjustment, restructuring and development, major changes will be to develop a key step.
shanghai shibang construction Shui Nissan 8000 tons of sand and gravel production line for benefit case is sturdy cement industry's determination to enter the field of sand and gravel production, therefore, the restructuring and development of cement industry but also for the development of sand and gravel industry in China played a significant role in promoting.
3, sand and gravel industry itself is constantly exposed to modern improvement will drive the industry to realize leap-forward development of the new one. It is understood that in ancient times, people learned to go to a house built of stone ground into sand, building a bridge, can be said that the sand and gravel industry in China has a long history.
With the continuous development of science and technology, some problems in the sand and gravel industry in China began to expose the most obvious is the slow sand and gravel production equipment replacement, had a great impact to the quality of the sandstone aggregate. Coupled with the sand and gravel aggregate is the essential raw materials of construction, therefore, the use of advanced, efficient, high value-added technology sand making machine, jaw crusher, impact crusher, crusher composite liner and other equipment will the production of quality sand and gravel to provide important protection to the health of our sand and gravel industry, sustainable development provides an inexhaustible driving force.
It can be said that the building will have gravel, therefore, continue the revitalization of the sand and gravel industry will also be an important indicator of national development, the contribution of the modern system of sand equipment, our infrastructure will be achieved sound and rapid development.

Inventory statistics: the iron ore port printed mine continued to decline significantly decreased
