Turn grief into strength Hongxing sand production line red in the reconstruction of the first line

 ;;; 5.12 3rd anniversary of Wenchuan earthquake anniversary, we cherish the memory of the past, but also to see the new look Wenchuan now, we understand the NDRC head of the State Council Information Office held at the May 10 press conference the revealed exciting news: Wenchuan earthquake reconstruction three-year mandate to complete two years of basic goals to fruition. As of the end of April this year, reconstruction projects and investments are completed about 95% of the planned mission by the end of September this year will complete disaster recovery and reconstruction tasks.

 ;;; infrastructure is critical livelihood of people, whether it is housing construction and make road and bridge construction, and ultimately, the use of sand and gravel aggregate, and broken machinery as sand The first stone aggregate crushing process, its role is self-evident, crusher not only improves the production capacity and crushing efficiency, but also expanded the range of applications, from limestone to basalt, from stone production to a variety of ore crushing, it can provide an unparalleled variety of pieces, crushing, ultra-crushing operation in crushing performance  slime dryer  . Jaw crusher is currently the most widely used crusher with crushing ratio, uniform product size, low operating cost, simple structure, easy maintenance, etc., divided coarse broken and fine broken in two, breaking strength of 350 trillion Pa less material, 1200 * 1500 jaw crusher equipment for the deep cavity, broken long trip, which will help material crushing, compare similar products and greater yield. Especially in the design and production of large jaw crusher aspect, already the leading domestic level  sand production line . Jaw crusher is mainly used in crushing production line first crushing process, can be used alone, it can also be crushed and other products supporting the use. Plus the use of large sand production line, sand and gravel aggregate production fully meet the market demand, accelerate the construction of infrastructure  broken jaw price . ;;; Modern society to promote the new concept of environmental protection and efficient, mining machinery is no exception, with the continuous development of mineral resources, the tailings produced only takes up a lot of land and pollute the environment, and constantly improve the tailings processing equipment crusher product of Some mining companies from improving economic efficiency considerations, has completed a number of iron tailings recovery plant, the use of the crusher tailings finishing, production of high value-added building decoration materials, and achieved significant economic benefits. Tailings will be the most extensive range of comprehensive utilization of mineral of the 21st century, the areas of greatest potential, will be the first to use the new resource people saving  Mill .

 ;;; iron tailings are concentrator under certain economic and technical conditions, with the crusher and mill the ore milled, select & ldquo; & rdquo useful components ; after the emission of waste, which is elected after ore concentrate remaining solid waste. It is a composite of mineral raw materials, in addition to containing a small amount of metal components, the main mineral component is gangue minerals such as quartz, pyroxene, feldspar, garnet, amphibole and alteration minerals  dryer manufacturer . Our iron ore resources disseminated fine grain size, generally subject to two-stage crusher and grinding mill, a few three-stage grinding, sorting, so in addition to a pre-selected portion of the coarse tailings thrown, most beneficiation discharge and fine-grained tailings dumps, tailings particle size is generally in & lt; 0.074mm accounted for 50% to 70%, only coarser tailings along the Yangtze River. According to the tailings particle size differences, mine tailings recovery and processing yield investments, etc., Vico offers many models of jaw crusher, impact crusher, cone crusher, milling machines and other high-voltage ultra-fine crushing equipment, selected according to the actual situation of different equipment combinations, iron tailings re-grinding, post-treatment process to achieve a certain degree of fineness preparation Glass, develop high-performance, low-cost high-end architectural or industrial tamper-resistant corrosion-resistant materials, improving the tail technological content and value-added minerals  jaw crusher .  
;  
 ;;; With the rapid development of the steel industry, the proportion of iron ore tailings in the industrial solid waste accounts is also growing. According to incomplete statistics, China has more than 150 kinds of minerals discovered, developed the establishment of more than 8,000 mines, the cumulative production of tailings 5.97 billion t, which accounts for all of stockpiled iron ore tailings tailings dumps near total 1 / 3%  roll break . Tailings or valuable elements tailings recovery is one of the measures the overall utilization of the primary and preferred, including the use of old tailings re-election, the newly created tailings re-election. Tailings dam and tailings dam can reduce maintenance costs, save broken mill, mining, transportation and other expenses, but also savings in equipment and new technology and greater investment in research, environmental protection and renewable energy, and therefore more and more social attention  mobile crusher .
