Sand maker works for aggregates particle shaping
Aggregates is the skeleton of concrete, whose partical shape is very important for concrete workability and strength. Both experiments and practice turn out that with the increasing needle and plate particle content of aggregates, the workability and strength of concrete becomes worse. Therefore, it seems a criticle thing to control the needle and plate particle aggregates content in sand making line.
As is known to all, sand maker contributes mainly to reshaping aggregates. With natural sand resources running out, artificial sand increased in the market. As a result, sand making machines also increased with various specifications and unevenness quality. Domestic well known crusher manufacturer Red Star Mining Machinery Co., with decades years of research experience, whose sand making line has been applied successfully at home and abroad.
It is understood that, the sand making production line produced by Red Star has excellent performance. Firstly, the stone materials are evenly sent to the crusher preliminary crushing through a vibrating feeder. Then, the material is fed to the sand making machine by belt conveyor for further crushing and after crushing the material will be conveyed by belt conveyor to vibrating screen for screening.Finally, the materials which achieve the finished size requirements will be sent into the sand washing machine for cleaning and finally become finished product discharging through the conveyor output; On the other hand, the materials which does not meet the finished size requirements will reback from the vibrating screen to sand maker for re-processing, thus forms a closed-loop recycled many times .
The production line consists of vibrating feeder, jaw crusher, cone crusher, impact crusher, belt conveyor, sand washing machine and fine sand recycling system and other system components. According to the needs of users, finished Size can be combined and graded. Among of them, the sixth generation of the sand making machine makes sand production line second to none in the industry.
It is reported that in quarry stones factory, as the heavy operation load, it is particularly important to select a stable performance, good wear resistance sand making machine. The sixth generation of sand maker uses a new type of crushing chamber, and increases equipped wheels weight and power, so that the crushing efficiency is 35% -50% higher than the traditional sand processing equipment, which without doubt improves the output. At the same time, the sixth generation sand making machine particle shaping effect is very good, finished gravel gradation is reasonable and fineness modulus is adjustable. The most important thing is the sixth generation Sand maker meets green development of energy saving, low noise, low vibration, no dust, it promots sustainable development of the sand and gravel industry.
Industry talent shortages while many out of job
Industry talent shortages while many out of job
Unemployment has reached record levels in many countries. Yet more than a third of employers around the world are still having trouble filling vacancies, according to a Manpower Group survey of nearly 40,000 employers in 41 countries. Workers in skilled trades (electricians, plumbers, bricklayers and so on) are in shortest supply, followed by ball mill engineers and sales people. Talent shortages are most acute in Asia, particularly in Japan where an ageing population is exacerbating the problem. Only in France has the proportion of employers struggling to find appropriate talent increased significantly since last year (from 20% to 29%). In Italy, by contrast, it has halved from 29% to 14%. Overall, employers are less concerned about the impact of skills shortages than they were in 2011. This may be because companies are becoming more comfortable conducting business in an uncertain environment where talent shortages persist.
There are a lot of commenters who seem to feel that the shortage of skilled workers is a fiction created by HR departments or unrealistic expectations. I work in manufacturing and there are real shortages out there in any profession that requires lengthy and difficult training. Chemical engineers (most engineers, really)are in short supply, in part because engineering grads often leave the field because banks, med schools, law schools, and most white collar professions would rather take a rigorously trained engineer over someone with a BA any day. Good instrument technicians, electricians, mechanics and pipe-fitters, all of which require long apprenticeships plus in-class training, are very hard to find.
We tell 18-year-old students to do what they love, and they take that advice and create time for an active social life plus video-game time by taking an undemanding major. Consequently they find they love college but are unprepared for life afterwards. The advice that I give my teenage kids is that by the time they hit 25, they need to have acquired marketable skills, through a professional degree or some other form of training. Those without marketable skills should be prepared to find employment unsatisfying, sporadic, and financially unrewarding. By all means, find something you enjoy doing, but don't forget you need those marketable skills. Life is not school. School is what you do before life really begins. Choose your school path to create the life experience you wish to have, not the school experience you enjoy now.
This chart highlights that growth areas of economies are in the cone crusher manufacturing minerals/oil and gas sectors in economies like Brazil, Australia and the US, whereas a lot of the people struggling to find employment are from finance and other service industries.
Machinery spurred on by retail trade technology
Machinery spurred on by retail trade technology
Perhaps I've got this wrong for machinery industry, but there is too little effort to address such concerns among advocates for manufacturing. I'm not interested in advocacy. I want to see a rigorous effort to control for these kinds of effects, even if that's likely to cast cone crusher manufacturing in a less flattering light.
And then, Mrs Tyson continues, there is the importance of manufacturing to innovation. She notes that manufacturing accounts for 68% of business R&D spending, which might well be true, but which tells us relatively little about contributions to innovation. (To what extent does spending translate into innovation?) Ditto this, from a Brookings' paper:
All manufacturing industries, including such reputedly “low technology” ones as wood products, furniture, and textiles, exceeded the non-manufacturing averages for both product and process introductions, while only a few science-and information technology-intensive non-manufacturing industries (software, telecommunications/ Internet service/Web search/data processing, computer systems design and related services, and scientific R&D services) equaled or exceeded the manufacturing averages.
Now wait a moment. Many more Americans work in non-manufacturing industries like wholesale and retail trade than in manufacturing industries, and so we might think it damning to hear that most of these non-manufacturing industries are not particularly innovative. Yet a moment's thought brings the realisation that the retail trades are in the midst of revolutionary change spurred on by technological, process, and business-model innovation. It just happens that this transformation is being led by, "a few science-and information technology-intensive non-manufacturing industries (software, telecommunications/ Internet service/Web search/data processing, computer systems design and related services...)".
This brings us to the crux of the issue. Mrs Tyson's piece was in some ways a direct response to a column by economist Christina Romer, who argued in early February that manufacturers don't deserve special treatment. Mrs Romer also came in for harsh treatment at this morning's Brookings event. Manufacturing advocates (and plenty of others, I suppose) seem to enjoy poking fingers in economists' eyes.
Mrs Romer, one critique went, was trapped within her discipline's framework, looking for and unable to find market failures sufficient to justify government intervention.
Strikingly, however, the policies supported by Mrs Tyson and by many of this morning's speakers are unlikely to inspire much opposition from Mrs Romer who, as a relatively orthodox economist, is happy to have government respond to clear market failures. Economists favour support for research, recognising the positive externality of general knowledge creation. They favour infrastructure investment on ball mill public good grounds. They welcome investment in training, given the spillovers from increased human capital investment. They favour a streamlined regulatory environment and a simplified tax code with more competitive corporate tax rates.

Support for manufacturing is back on the agenda in America, thanks in part to concerns about long-term growth prospects and the "challenge" posed by China. Politicians as different as Barack Obama and Rich Santorum have expressed a desire to do more to help manufacturers. This all makes most economists uncomfortable, not least because most pro-manufacturing argumentation in recent decades has tended toward a thinly-veiled mercantilism. I, too, am sceptical about the importance of government support for machinery cone crusher manufacturing, or indeed of the broader merit of manufacturing activity, relative to other economic pursuits. Why does manufacturing matter?
Laura D'Andrea Tyson recently wrote a piece for Economix examining precisely that question, part of a new effort to make manufacturing support respectable among dismal scientists. I found it less than convincing. Manufacturing matters, she began, because America needs to close its current account deficit. Ok, but exports of services and resources combined are now larger than exports of manufactured goods. Are we sure it isn't easier, or more important, to scale up the former rather than the latter? Neither is it clear that manufacturing trade balances, as presently computed, accurately account for the actual American content in traded goods. (Very little of the value added in iPhones "imported" from China is accounted for by Chinese activity.)
Moreover, trade balances are essentially a macro issue. Even if one agrees that it's critical to increase net exports, it isn't clear that micro reforms are nearly as important as macro capital flows. The trade-weighted dollar is 30% weaker than it was a decade ago, and further declines are likely as (or if) the crisis-period flight to safe assets reverses. That, and not the merits of manufacturing, is the biggest trade concern.
Mrs Tyson goes on to argue that manufacturing matters because its jobs are high-productivity, and high value-added positions that tend to pay well. Perhaps, but this may well confuse cause and effect. High-wage manufacturing jobs tend to leave America when workers aren't sufficiently productive. There is a selection effect at work, in other words. Skill- and capital-intensity also matter, of course, but that's true across sectors. The Brookings Institution's Metropolitan Policy Programme hosted a symposium this morning on why, and which, manufacturing matters, in which a similar point was repeatedly made—wages are higher in manufacturing. One speaker noted that controlling for age and education a manufacturing worker such as a ball mill technician earns around 7% more than a non-manufacturing peer. But what if one controls for location? Is it more important to move people from non-manufacturing positions to manufacturing positions, or to move them from low-wage metropolitan areas to high-wage ones?

Gao Hua had the highest accuracy rate at 60 percent with 55 correct recommendations out of 88, followed by Capital Securities Corp. (6005) and UBS AG (UBSN), according to Bloomberg Rankings. Masterlink Securities Corp., Morgan Stanley, China International Capital Corp., HuaChuang Securities, JPMorgan Chase & Co. (JPM), Credit Suisse Group AG (CSGN) andDeutsche Bank AG (DBK) rounded out the top 10 brokerages.
Morgan Stanley Huaxin Securities Co., based in Shanghai, said on April 24 that the Chinese index may rally another 30 percent this year, led by banks and developers. Guotai Junan Securities Co., also located in Shanghai, forecasts the gauge may hit 2,800 by the end of the second quarter. Morgan Stanley and Guotai Junan advised buying stocks before the Shanghai gauge’s last bear market ended in July 2010.
Wang has an overweight allocation for stocks in the insurance, property and construction material industries, suggesting investors should hold more of the shares than are represented in benchmark indexes. Gaohua cut the coal industry to neutral from overweight, he said.
Wang recommended Chinese consumer and health-care stocks in April 2010, and they finished among the top three best- performing industries that year even as the Shanghai Composite slumped. A combined 33 percent loss in 2010 and 2011 for the Shanghai index dragged down the gauge’s valuation to a record low of 8.9 times estimated earnings on Jan. 6, according to weekly data compiled by Bloomberg. The index now trades at 10.2 times estimated profit, compared with the MSCI Emerging-Markets Index’s multiple of 9.7 times.
China’s stocks fell yesterday as a May 29 report from the state-run Xinhua News Agency damped speculation of increased government stimulus. Credit Suisse said in a May 28 report that spending in response to China’s economic slowdown will probably range from 1 trillion yuanto 2 trillion yuan.
“The Chinese government’s intention is very clear: It will not roll out another massive stimulus plan to seek high economic growth,” Xinhua reported, without attributing the information. “Current efforts for stabilizing growth will not repeat the old way of three years ago.”
China’s central bank has cut lenders’ reserve-requirement ratios three times since November, fueling speculation the government will allow banks to lend more to cash-strapped companies and step up ball mill machinery investment. New bank lending was 681.8 billion yuan in April, down 32 percent from the previous month, central bank data showed on May 11.
China will start a number of “key infrastructure projects that cone crusher will contribut to are vital to the overall economy and can facilitate growth” and speed up construction of railway, environmental protection and rural projects, the government said on May 23, summarizing a meeting of the State Council, or cabinet.
Slowing inflation leaves room for economy growth
Slowing inflation leaves room for economy growth
While the Chinese government is vowing not to spend as it did during the 2008 global financial crisis, the most accurate analysts say the benchmark index for the nation’s stocks will keep rising. And the machinery cone crusher manufacturing industry is bound to stimulating economy.
The Shanghai Composite Index is poised to gain 15 percent from yesterday’s close to 2,750 by year-end as slowing inflation allows the government to loosen monetary policy and banks to lend more to companies, according to Beijing Gao Hua Securities Co., Goldman Sachs Group Inc.’s partner in China and the firm with the most correct predictions for yuan-denominated A shares in the two years to January 2012, based on Bloomberg Rankings.
The benchmark stock index has climbed 7.9 percent this year on speculation the government will accelerate measures to boost the world’s second-biggest economy after gross domestic product grew at the slowest quarterly pace since 2009. The government said on May 29 it has no plan to introduce stimulus on the scale of measures in 2008, when policy makers unveiled a fiscal package of 4 trillion yuan ($629 billion).
“We remain positive on the market this year,” Wang Hanfeng, China strategist at Gao Hua (GS), said in an e-mailed response to questions. “With inflation easing, there is a shift towards policy loosening which will help improve the liquidity situation and support the valuation expansion of A shares.”
Slowing inflation leaves room for the government to stimulate the economy as policy makers turn their attention to growth, said Wang. A statistics bureau report on May 11 showed China’s consumer prices rose 3.4 percent in April, below the 3.6 percent rate in March and the government’s full-year target of 4 percent. The economy grew 8.1 percent in the first quarter, the least since the three months ending June 30, 2009.
The Shanghai Composite slipped 0.5 percent to 2,372.23 at today’s close. It lost 1 percent this month, compared with a 13 percent plunge in Brazil’s Bovespa Index, the 6.7 percent drop for the BSE India Sensitive Index and the 11 percent slump inRussia’s Micex Index.
Gao Hua’s stock recommendations on Zoomlion ball mill Heavy Industry Science & Technology Co. (000157) and Poly Real Estate Group Co. were the most accurate based on an analysis of recommendations on 135 A shares from more than 400 analysts at 43 brokerages. The analysts were ranked according to the accuracy of their estimates between Jan. 1, 2010 and Jan. 9, 2012.
Machine technology for industry is consolidating

In the machinery trains manufacturing industry, several factories shut during a three-year ordering hiatus when the rail network was ineptly privatised in the 1990s; contracts have become ever scarcer as the government parcels up rolling-stock cone crusher procurement into huge purchases. No new deal has been closed in Britain since 2009.
Still, all manufacturing firms depend on their order book. Aerospace companies have found an alternative source of profit: servicing the goods they make. Rolls-Royce already gleans 51% of its revenue from servicing its engine fleet: its Trent jet engines are continuously assessed from a slick operations room at Derby. That figure is set to increase, the company says. For Bombardier’s global transport division, by contrast, the share of revenue from services went down between 2007 and 2010, from 21% to 14%.
Moreover, aerospace—including making the guts of aircraft engines, as Rolls-Royce does—is a global industry with standardised technologies. Only the paint job and interiors differ between planes made for different countries. Train production, by contrast, has until recently been largely national, which made it hard for manufacturers to achieve scale or make widely marketable goods. While Rolls-Royce hawks its wares around the world, Bombardier’s facilities (across Europe and North America, as well as in Derby) have depended on single contracts to build local rolling stock. Each type of train Bombardier produces at its various sites is a different size and specification; fewer than 10% of trains made at Derby are exported.
That insular model has now begun to change—but not to Bombardier’s advantage. Standardisation of technology is increasing and the industry is consolidating. Despite the popular stereotype that continental Europeans favour their own national suppliers, protectionism is loosening: in 2010, France’s state-owned Eurostar agreed to buy German-built Siemens trains; Spain’s Renfe also uses German express vehicles. That means the Bombardier factory in Derby can no longer rely on its status as Britain’s sole trainmaker. (Already in 2005 Hitachi won a deal for the British railway but shipped the fully assembled trains from Japan; the company will soon open a new facility in Britain but the carriage casings will still be made in Japan.)
Meanwhile Rolls-Royce has sought to insulate itself from the quirks of procurement by applying its design to ball mill machinery industries: 80% of the gas-turbine technology used in its best-selling jet engines is the same for the energy and marine sectors. All of which leaves Rolls-Royce less reliant on the British market: over 85% of its revenues are from exports.
