SBM machine crusher takes gangue seriously to reclaim processing
Current, our country is changing flying development level at industrialization, city, the wastage of mineral products resource is big, external depend on sb or sth for existence is spent taller, value of global mine product is rising ceaselessly, increased the pressure of resource safety, increased what mineral products tastes demand enterprise to produce at the same time capital. And our country is the mining industry on the world produces one of big countries, development has used a large number of gangue that accumulate for a long time, make its " become useless to be treasure " . The stone crusher to gangue treatment that right now research and development of limited company of Henan SBM machine makes from thick the treatment that cuts the fine broken one continuous line that finish is broken, make its quadratic is used alleviate effectively resource and environmental pressure.
Gangue is mining company is in what condition of certain technology economy issues eduction " litter " , but it is 2 potential resource at the same time, when condition of technology, economy allows, can undertake be developinged effectively again. Our country is in all the time advocate the issue with energy-saving environmental protection, each big province city and various places are strict according to energy-saving decrease a concerned policy, encourage civilian battalion enterprise to aim at environmental protection energy-saving on project, advanced the progress step that mineral products resource uses integratedly effectively.
According to statistic, before 2000, the gangue gross that our country mine yields is 5.026 billion tons, among them, quantity of iron ore gangue is 2.614 billion tons, the gangue quantity of main nonferrous metal is 2.109 billion tons, gold gangue quantity is 272 million tons, other 31 million tons. 2000 our country mine year discharge gangue to achieve 600 million tons, press this computative, the gross of existing gangue is controlled 8 billion tons. The resource that the ode in gangue puts is considerable, use value very big. In addition, mine gangue store up still took up a large number of farm, forest land, also have certain pollution to the environment.
And nearly two years, our country is in all the time advocate the title with energy-saving environmental protection, each big province city and various places are strict according to energy-saving decrease a concerned policy, encourage civilian battalion enterprise to aim at environmental protection energy-saving on project, 2009 1 come to go up newly May gangue uses a company integratedly many 200, total investment achieves nearly 20 billion yuan, advanced the progress step that mineral products resource uses integratedly effectively.
In the light of gangue broken reclaim use, limited company of machine of SBM of manufacturer Henan province adopts our country's famous crusher equipment major necessary and high grade efficient technology, production makes an advanced large crusher equipment. Among them equipment includes gnathic type crusher, strike back type crusher, pound type crusher, exceed grinding machine to wait, have effective treatment to mine gangue, its apply gangue of iron ore of mill of mine of countrywide each general election already successfully to reclaim in using.
