Slag usually refers to water slag, furnace slag, and other such cohesive materials that have been polymerized through high temperatures. Slag mainly comes from factories, such as cement plants, thermal power plants and smelters.
What about the secondary use that slag can achieve? Slag actually plays an important role in industrial production, especially in some large heavy industry factories, which mostly choose to use slag refining and processing into slag cement, slag micronized powder, slag powder, slag silicate cement, slag cotton and other substances. Blast furnace slag can also be used as raw materials for cast stone, microcrystalline glass, fertilizer, enamel, ceramics, etc.
1, microcrystalline glass, slag manufacturing microcrystalline glass is lighter than aluminum, chemical erosion resistance, heat resistance and mechanical strength are high, but also a good electrical insulation materials and decorative materials.
2, road construction, slag can be mixed after a certain degree of crushing to form the material for building road base and bedding, and better than the mixed block stone foundation level. Can play the role of insulation, construction operation is simple.
3, slag micronized powder, the main use is in the cement mixing and adding in the concrete, there are three main forms of use: admixture form, admixture form, the main mix form, can enhance the cement, concrete hardness and certain characteristics.
How to choose the right grinding equipment for processing slag? Slag micronized powder as an admixture of cement can improve the compressive, tensile and flexural properties of concrete, and it has been developed in the building materials industry as a mainstream trend, Liming Heavy Industry recommends an adapted grinding equipment - LM Vertical Mill.
LM Vertical Mill
LM vertical mill combines crushing, drying, grinding, classifying and conveying in one, which can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic mining and other industries.
At the same time, it should be noted that when choosing a mill, centrifugal and rotary type should not be used to produce slag micronized powder, which has low powder selection efficiency, large cycle load rate and low economic efficiency, try to choose eddy current separator.
With the development of industrialization, the emissions of waste rock, tailings, slag, etc. are growing geometrically, a large amount of industrial solid waste will cause serious damage to the ecological environment, therefore, how to convert waste into resources, so that it can be better recycled, has become an urgent economic development in China, many people have seized this business opportunity, have invested in it.
