Steel slag recycling


Xfce - Jul 3 2014
not answered
Question:The steel slag as a by-product of iron factory production, with hydraulic cementitious, there are high density, steel slag crushing plant high strength, surface roughness, good stability, wear resistance and good durability of gravel. It is not difficult to find, scrap steel slag on soil, water, vegetation destruction of the bud. And the waste slag in a parasitic bacteria, so the biological pollution also can hardly be avoided. If the steel slag can be developed deeply and utilized, not only can eliminate environmental pollution, but also can create enormous economic benefits. Slag containing iron slag 10% right and left without treatment each year there will be a large number of steel slag erosion emissions of slag powder can destroy the land vegetation. Air pollution source and surrounding the city.
Therefore the steel slag processing and comprehensive utilization, zenith mining and construction the waste into useful products, and ensure normal production in iron and steel enterprise. The need for energy conservation, but also the urgent need of the comprehensive management of environmental protection. The process of steel slag treatment: the major steel slag treatment generally to the magnetic separation process. Magnetic separation process is a method of treatment for sorting in a magnetic field by magnetic differences of various substances. Steel slag treatment method with steel slag and primary steel slag as raw material, using a closed loop production process, respectively, by screening the negative pressure ball milling process, the dry magnetic separation and air classification, to obtain four kinds of high quality and high added value products, the iron content of greater than 90% can be used for making high quality scrap, cone crusher for sale used for the grade of iron concentrate iron, used for steel slag cement and concrete admixture and high activity for steel slag asphalt concrete pavement of high grade highway pavement aggregate. Truly slag zero emissions, thoroughly solve the pollution of steel slag to the environment. Steel slag choose iron equipment line choice has become a pressing matter of the moment. Shanghai SBM heavy equipment Co. Ltd., magnetic separator, production of professional equipment, to provide professional and first-class service for you, please pay close attention to more products.

 Granny thinks it is much more usable than Gnome 2
 Canonical is embarrasing itself with this split project
 Gnome 3 default shell is much better
 I dislike Unity, Gnome 3 default shell is alien technology!
