Crushers Made Great Contribution to Mining Industry

With the rapid development of the steel industry , the proportion of iron ore tailings in the share of industrial solid waste is also growing . According to incomplete statistics, China has more than 150 kinds of minerals found , developers build more than 8,000 mines , total production of tailings 5.97 billion t, which accounts for all of the stockpiled tailings stockpile of iron ore tailings total nearly 1 / 3% . Tailings or recycling of valuable elements is one of the measures the overall utilization of the main tailings and preferred , including the use of old tailings re -election , re-election of new generating tailings . Tailings dams and tailings dams can reduce maintenance costs , saving broken mill, mining, transportation and other costs, but also saving equipment and greater investment in new technology developed , so more and more attention . Iron concentrator tailings are under specific economic and technical conditions, with crusher and mill the ore milled , select " useful components " after the waste emissions , which is elected by the 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. Dissemination size of China"s iron ore resources thin , generally subject to Sec crusher and grinding mill , a few three sections of grinding , sorting , so in addition to a preselected portion of the coarse tailings thrown out , most of the discharge and beneficiation stockpiling of fine-grained tailings , tailings particle size is generally 0.074mm accounted for 50 % to 70 %, only coarser tailings along the Yangtze River . According to differences in particle size of tailings , mine tailings recycling and processing of investment yield , etc., Henan Fote provide multi- model jaw crusher , vertical roller mill , super pressure trapezium mill ,...
