Economic Forecasting: 2 years before the influx of Australian mining summit

Australia Daily News: Federal Resources Minister Ferguson (Martin Ferguson) last week issued a "mining boom has ended," remarks, but economic forecasting organizations BISShrapnel on Monday the report has supported the attitude of the government singing Mining tide longevity. According to this study, the influx of mining in Australia are from the peak a few years time, let alone end.

The report also forecast towards inevitable deceleration of the road when the mining sector, the other sectors of the economy will rise up to fill the gap.

On Sunday, a number of cabinet ministers have sound stressed the end of the mining boom in the distance there is quite a long section of the road, Figure offset by BHP Billiton announced last week that it set aside $ 30 billion Olympic Dam broaden project, and Ferguson's controversial remarks triggered economic stall worried.

A reversal of the outside world for the gloomy forecast of Australia's key export products, BISShrapnel think, has signed a contract resource projects mean mining investment at least until 2014 in order to climb to the top, Queensland and Western Australia in the next 3-5 years there will be a series of large-scale projects . "After this, the non-mining investment will grow steadily, becoming the engine of economic development, to complete the transition smoothly." BISShrapnel the the chief economics FrankGelber said, "The purpose of our report is to disperse the tension caused by the mining boom end" discussion. "he said, Australia's economic growth rate of 3% this year and next year. BISShrapnel think commodity prices continue to remain in a high state will allow the Australian dollar in the next few years "to continue strong, which pressure is applied to other export-oriented industries.

On Sunday, the Trade Minister Emerson (Craig Emerson) Mining tide even half-way have not come to the Workplace Relations Minister Shotton (Bill Shorten), pointed out that his department predicted that the next five years, the mining sector will create 100,000 jobs. Shotton attempt to disguise the Cabinet divided on this issue. He said, "Ferguson said yes: We may have to a vertex in price, but the size of the (mining investment) still in expansion, there are many items (to be started soon).

Finance ministers Swann (Wayne Swan) claimed Mining tide should be understood as "a series of prosperity", "price of prosperity, the prosperity of the investment boom and exports." Although the price boom has topped out, but The investment boom is still some distance away from the end. "

Resource and Energy Economics Bureau predicts that this year's commodity export earnings will reach a record 209 billion expansion of the scale to offset the impact of the price decline. Written by Dr (HaibinZhu), JP Morgan chief China economist at last week's visit to Australia, said that although China's demand for Australian minerals will slow, but will remain high in the next 5-10 years.

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.

Imported ore price has been cut domestic mining enterprises sell mine

With imported ore prices continued to fall, part of the domestic mining enterprises under threat.

Yesterday (August 28), the "Daily Economic News" reporter learned that, by the downturn in the steel market dragged down imported ore price continues to fall and enlarged decline, the price of some varieties have been significantly lower than the domestic ore. Mine the emergence of low-cost imports, which more than domestic ore lost the price advantage, and also forced the shutdown of some domestic small and medium-sized mining enterprises delisting.

Imported ore price has been "cut"
Imported iron ore market to plumb all the way, because businesses selling pressure significantly expanded ore price decline in the past two days, the market cheap deal emerge. "Said Mysteel analyst Zhu Xian,.

Latest statistics show that to Tianjin Port 63.5% Indian iron ore, for example, as of the 28th, Tianjin port price of 750 yuan / ton, a decrease of 17.6% over the same period last week, a decrease of 20.2% over the same period from the previous month, a decrease of about 44 compared to the same period last year %.

"Daily Economic News" reporter found that more than Indian ore prices fell significantly, other imported the same ore prices have not stabilized, PB powder outside the disk has fallen below 100 U.S. dollars / ton, compared with last year, more than 190 U.S. dollars / ton, the price close to "cut".

Yesterday, the miners usual, the tender, but the basic domestic corporate demand procurement and light reaction. Which, only three cases of tender along with the ending of the auction of the Australian mining, the two Pakistan mine tender ending of the auction.

Many industry insiders told reporters, imported ore price deep down steel prices fell sharply Forced "If you look at the price relationship between the decline after 2008, the ore price not to the corresponding price.

In addition, the steel procurement enthusiasm is not high, the late iron ore prices are still down space.

The data show that as of August 24, the 30 major ports in the country's total iron ore stockpiles at 98.95 million tons, an increase of 830,000 tons over the previous week, for two consecutive weeks rose, the total stock hit a new 23 weeks high. Compared with the same period last year, total inventories increased by 3.74 million tons.

Domestic mining enterprises sell mine
Reporter learned that, due to the imported ore prices remain high for long, the enterprise inside and outside the mine's procurement mostly to comply with a ratio of 4:6. Appear as the low-cost advantages of imported ore, the ratio of imported ore for domestic steel mills rising, which makes part of the domestic mining enterprises deep selling mine "situation.

Yesterday, who said in an interview with the "Daily Economic News" reporter, "If the imported ore ton drop in price to $ 100, the value for money outside the mine more obvious, the buyer also more inclined to purchase outside the mine."

According to statistics, currently 50 mines operating rate was about 62%, while the good times, the start of these enterprises can reach 90%.

The person said domestic ore not to stop production of large area even shuffling, but does have some small mines discontinued phenomenon, "because now outside the mine not only cost advantages, to some extent better than domestic ore use. "

It is reported that 120 U.S. dollars / ton has been regarded as a psychological barrier of domestic ore, imported ore price below that price, domestic enterprises will be a lot of selection of imported ore.

"At present, the proportion of imported ore generally up to about 80%, even 90% or all outside the mine." Steel sources said domestic ore price has fallen to a lot of gains and losses from domestic mines line or the line between life and recently, domestic The mine shutdown delisting phenomenon increased significantly.

In fact, in July, domestic mineral there have been more significant decline. According to the Bureau of Statistics data, the amount of domestic iron ore in June to 125.693 million tons, while the July data fell to 115.461 million tons. Actually discontinued more obvious than the Bureau of Statistics. "Zhu Xian said.

Iron ore prices fell to the lowest level in nearly three years is expected to continue to reduce

Following the issue the first time in three years, falling profits, earnings for the year in a few days ago, BHP Billiton CEO, Reese said yesterday that the recent mining price correction shows that the long-term price may be lower than the current price. BHP Billiton plans in each of the next two years, production increased by 10%, the price decline in credit for most products over a longer period. In expert opinion, the iron ore import prices fell to its lowest level in nearly three years, is also expected to continue to reduce.

Must and must Billiton in the earnings report said, due to weak commodity prices, the company in as of June 30 Ri's fiscal year 2012 profit slipped 35 percent to 14.7 billion Australian dollars ($ 15.4 billion), is the international financial crisis since the first time the profit decline. Iron ore over the past five years has been a cash cow for the mining sector, falling prices are significantly affect the Tamsui River Valley, Rio Tinto, BHP Billiton profitability.

 

Yesterday, 63.5% Indian iron ore futures offer 106 to 108 U.S. dollars / ton, already below the $ 120 / ton psychological barrier. Early last year, more than 200 U.S. dollars / ton price compared to prices close to "cut". The end of February 2010, Vale was the first to reach an agreement with Japanese and Korean steel mills, then the quarter reached agreement ore price is 108 U.S. dollars / ton. This means that the current ore price lower than the agreement in early 2010 price, fell to its lowest level since the end of 2009.

Analysis of the industry, the growth rate of the global pig iron production, iron ore production is much lower than the growth rate, which is the root cause of the iron ore prices fell. "In 2010 and 2011, iron ore prices rising all the way, leading to capital flooded into the mining industry, iron ore production increased rapidly after two years of development."

At the same time the demand for iron ore, iron and steel enterprises has not increased significantly. China is the world's largest importer of iron ore, from the beginning of the fourth quarter of last year due to overcapacity, China's iron and steel enterprises into a position of industry-wide losses, and experts predict that the phenomenon of short-term loss is difficult to change. The loss-making enterprises to reduce production has become an inevitable choice. In the port, high-priced inventory accumulation. While the rest of the world's major economies have also been the impact of the weak economy, iron ore demand is not strong.

Several situations contrast to an analysis, the iron ore market oversupply situation will continue. "However, industry insiders believe, the foreign miner of iron ore production to lower cost, even if the price drops, but mine corporate profit margins are still large. The last two years of rapid growth in iron ore prices have overdrawn the kinetic energy of the iron ore to rise in the next few years.

The impact crusher institutions made ​​wearing parts and broken adjustment

Impact Crusher with the crusher equipment technology improved, focusing on the overall market, according to their own innate high level of technical advantages of R & D and manufacturing, the type of crusher than large, high efficiency, strong production capacity, uniform particle size, high efficiency and low consumption, low carbon environmental protection, is ideal for crushing ore or rock crushing machinery.

Impact Crusher Shanghai Shibang Machinery Co., early R & D and manufacturing of a high-efficiency, high-performance, high environmental mining crusher equipment. Currently it is a broken mechanical impact energy to break material. Material into the plate hammer area by the high-speed impact of the board hammer and broken, and was thrown to the installation broken again on rotor above the counterattack device, and then bounced back to and from the counterattack lining board hammer role of district re-broken. This process is repeated until the material to be crushed to the desired particle size is discharged from the bottom of the machine so far. The gap between the adjustment counterattack frame and rotor frame can reach the purpose of changing the material discharge size and material shape.

Impact Crusher advantages and features: hard rock crushing, keyless connection, high-efficiency plate hammer, a unique gear counterattack liner, the products drawing on advanced domestic technology optimization design can handle particle size of not more than 120-300 mm, granite, basalt, limestone and other materials with breaking strength of not more than 320 MPa. Great crushing ratio, high crushing efficiency, easy maintenance features. Cubic shape of the broken material, highway, railway, water conservancy, airport, construction industry, the production of high-quality stone preferred device.

Slag Impact Crusher use the the board hammer on the high-speed rotation of the rotor, to generate high-speed impact of material fed into the crushing chamber and broken and crushed materials along the tangential direction of the high speed counterattack thrown to the other end of the crushing chamber board, again is broken, and then from the rebound counterattack plate to plate hammer, continue to repeat the process. In commuting between the material strike against each role. As the material by plate hammer blow, the collision between the impact of the counter plate and the materials, the material constantly cracks and loose Erzhi crushed. When the material particle size is smaller than the gap between the counter plate and plate hammer is discharged outside of the crusher.

Materials by the first shock, the machine back and forth repeatedly throwing. In this case, the material due to the partial destruction and reverse, are no longer expected to trajectory movement rules, but repeated impact Crusher cavity different location, and then the material into the second chamber of the Crusher within a further impact crushed.

The back-breaking is dedicated to the crusher for crushing all kinds of hard rock, the kinetic energy of the large and ore contact process, some accessories normal wear and tear. The Crusher Parts major including various types of liner plate hammer, counter rack, counter plate, square steel, fenders, small counter plate, wedge block the compression block platen rotor.

No1, counterattack breaking counterattack plate. Counterattack board's role is to withstand the impact of the plate hammering out materials and materials by impact and crushing, and the impact of the crushed material re-bounce impact zone, impact crusher again to obtain the desired product size.

No2, counterattack broken plate hammer. Shape and fastening plate hammer and work load are closely related. The board hammer should be designed to meet the work is reliable, easy loading and unloading, and the request of the board hammer metal utilization. The plate hammer generally use high chromium cast iron, high manganese steel and other wear-resistant alloy steel. Many shape of the hammer plate, has a long strip, T-shaped, S-shaped work-shaped, hatchet and band trough shape, is now generally a long strip.

No3, back-breaking material. Counter plate is generally steel plate welded into its counterattack surface equipped with wear-resistant liner, but can also be used counterattack roll or grate plate. Counterattack surface, with a grate seam less fine fraction content of their products, equipment production capacity can be increased, power consumption province. But there is structure is complex, difficult to replace counterattack surface wear, wear and other defects.

No4, counter breaking counterattack rack. Impact crusher is equipped with two the counterattack rack, weight suspension structure. Each counterattack frame is individually supported in the crusher rack. Crusher working, the weight of the to counterattacks frame membership, to maintain its normal operating position, over iron counterattack rack quickly lift barter is excluded, again to return to the original position. Counterattack the gap between the carrier and the rotor can be adjusted by a suspension bolt. Interchangeable counterattack lining counterattack in the rack with oblique structure fixed. The counterattack liner can be replaced from wear larger wear a smaller place.

Counterattack board many forms, mainly broken line and the arc-shaped two categories. The mansard counterattack face to make a material impact are approximate vertical direction, and therefore achieve the best crushing effect on the points of the counter plate. The arc-shaped counterattack surface can rebound came out by the counter plate material block in the center of the circle area intense impact crush zone to increase the freedom of the material impact crusher effect.

Used Mobile Impact Crushers

No5, Crusher rotor. The rotors were powered by a whole cast steel, durable structure, easy to install board hammer its quality to meet the crushing requirements. The rotor body is the heart of the back-breaking machine, the rotor frame made of welded steel plate, plate hammer fixed in the correct position, axial spacing devices, can effectively prevent the plate hammer ran. Board hammer with high wear-resistant material. The entire rotor having good static and dynamic balance, and impact resistance. Small and light Crusher rotor also can be welded steel plate.

Impact Crusher design improvements as well as the body improved

Finite component analysis model dependant on the dynamics on the affect crusher works to determine the communicate with collision, calculated by a software program force in numerous pieces on the total crushing procedure to get the different components on the collision position tension distribution analysis a rotor overall body three various pieces on the tension variations during the crushing procedure, the tension curve, these deliver the idea for that design and style and advancement of operation on the procedure will affect crusher framework.

Impact crusher overall body in improving the communicate with surfaces on the upper and decrease overall body by only one floor communicate with to confront communicate with. Cuts from the edges on the width 55mm decrease overall body underneath the upper overall body stop floor corresponding place welding width of 50mm, a thickness of the metal plate of 25 mm, notice leaving the opening gap of 5 mm, and after that the underside on the decrease overall body welding thickness is twenty metal plate, so that the upper and decrease binding floor forming The labyrinth seal. Affect Crusher curved around the overall body flange, primary M5 bolts wool felt mounted during the still left flange seal groove the correct flange Correspondingly clean cambered. Immediately after transformation the still left flange groove with adhesive then wool felt, Ran round metal welding in right flange groove corresponding floor in 6, so that the round bar entirely around the flange communicate with stress felt than the primary seal better.

Crusher crushing impact the subsequent factors:

No1, Affect Crusher Once the crushing impact has not yet damaged the material is greater than the discharge opening dimension, high-speed rotation on the plate for the discharge hammer and damaged.

No2, Affect Crusher rebound damaged, damaged product is really Ministry of unrestricted scattered, affect crusher performing pieces, you will find explained in detail.

The No3, Affect Crusher liberty of damaged product in to the crushing cavity quickly with the affect on the board hammer, mutual affect involving the material, the friction involving the plate hammer and resources, supplies and resources, product crushing because of to these consequences.

No4, affect crusher board hammer screws, mounted insertion strategy, plus the wedge mounted together with other kinds of mounted set up during the crusher rotor. Screw mounted framework during the kind of easy, much more standard use. Its cross segment is comparable to rectangular, elongate, lengthen the width path is set up during the rotor on the pallet. Should rely on the mounted kind, generate the problems for that application of substantial hardness resources. Work hammer plate 30-40m / s, even around a linear velocity of 50m / s crushing the material, the wear is incredibly major, the hammer plate constantly transforming not only take in plenty of steel product, and also due to the fact Quit drastically influence the productiveness on the crusher, even the restrictive elements of the output.

To adapt into the application of substantial hardness resources, distinctive attention into the good quality on the casting, primarily the mounting floor on the geometric dimensions and form on the error to be certain that within just an affordable range, so that you can assure clean and reputable runtime.
