The difference between blast furnace slag and water slag and steel slag and what mill to choose
Blast furnace slag, water slag, steel slag collectively referred to as industrial waste, in advocating the effective use of resources, protect the environment under the policy of being more and more people pay attention to the potential value of the market is also constantly being tapped, regardless of which kind of industrial waste to achieve the next level of product processing must be now by the Raymond mill grinding powder can be, for the different industrial waste on the choice of milling equipment is also slightly different, with these questions below let's go to the Explore.
Blast furnace slag, water slag, steel slag similarities and differences are?
Similarities: the same belongs to industrial waste (solid waste), the environment has a certain pollution hazards, after crushing and grinding can be used as a variety of raw materials as a substitute for the use of ore materials, economic and environmental protection.
Differences:
Source differences: blast furnace slag, water slag belongs to the smelting of pig iron from the blast furnace waste, water slag is a kind of blast furnace slag, which also includes: air-cooled slag, expanding slag, slag cotton, etc., and steel slag is the slag discharged from the steelmaking, according to the type of furnace is divided into converter slag, flat slag, electric furnace slag and so on.
Main components: Blast furnace slag is mainly composed of CaO, SiO2, Al2O3, steel slag is mainly composed of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus and other oxides.
Application scope: Blast furnace slag can be used instead of natural stone for highways, airports, foundation projects, railroad road slag, concrete aggregate and asphalt pavement, etc., can be used for: preparation of slag crushed stone concrete, in the application of weak foundations, with slag crushed stone as a base material for paving asphalt pavement not only bright and non-slip performance is good but also has a good wear-resistant performance of the shortening of the braking distance, used in railroad road slag can be appropriate to absorb the vibration and noise generated by the train when walking. Vibration and noise. Expanded slag beads is a porous lightweight slag formed by cooling blast furnace slag slag with appropriate amount of cooling water, production methods include spraying, spraying, rift valley method, roller method. It can be used to make light aggregate, used to make interior wall panels floor slabs, etc., and also used for load-bearing structures. Blast furnace slag can also be used for the production of slag cotton (blast furnace slag as the main raw material, melted in the melting furnace to obtain the melt and then refined and obtained a white cottony mineral fibers), microcrystalline glass, silica-calcium slag fertilizer, slag casting, hot casting slag and so on.
The use of steel slag varies according to the composition, calcium, iron, magnesium and manganese content of steel slag used for road bedding, structural layer, especially suitable for use as asphalt mix aggregate paving pavement layer, steel slag road construction, with high strength, wear resistance and skid resistance, good durability, low maintenance costs and other advantages. High-phosphorus steel slag used as fertilizer, steel slag in the calcium, silicon, manganese and trace elements are fertilizer, can be used as slag fertilizer applied to acidic soil. China's use of slag as cement clinker more, all types of steel slag can be used as pit filling, land reclamation materials.
The choice of industrial slag mill, according to the nature of the slag itself is the primary premise, the general hardness of industrial slag are not very large, although like water slag and other potential water-hardened gelling properties, but the hardness is less than 9, so the selection of the range of mills on a wider range of some of the specific types of mills and model selection also need to be more later production process to determine the quality of different applications of the industry on the quality of industrial waste slag requirements of difference! Increase, for example, do concrete aggregate fineness requirements are lower, and for cement clinker needs 325 mesh fineness requirements, some special industry fineness requirements are higher need to be equipped with special ultra-fine powder grinding equipment, comprehensive years of experience in the production and operation of the view: Raymond mill, high-pressure mill, European version of the mill, etc. can be applied to slag milling process, the finished product fineness 35-425 mesh between the adjustable, fully meet the requirements of the conventional fineness of the powder. Requirements.
