Slag Crushing Plant Sale
Slag is a by-product generated during manufacturing of pig iron and steel.It is produced by action of various fluxes upon gangue materials within their on ore during the process of pig iron manufacturing in blast furnace and steel manufacturing in steel melting shop.Primarily, the slag consists of calcium, magnesium, manganese and aluminum silicates in various combinations.The cooling process of slag is responsible mainly for generating different types of slags required for various end-use consumers. Although the chemical composition of the slag may remain unchanged, physical properties vary widely with the changing process of cooling.
Steel slag are produced at steel melting shop during steel manufacturing. To produce steel, removal of excess silicon and carbon from iron is achieved through oxidation by adding limestone and coke. The steel slag contains higher amount of iron and its physical characteristics are similar to air-cooled iron slag. The iron content is the major basic difference between BF slag and steel slag.
The slag produced at blast furnace during pig iron manufacturing is called blast furnace slag. The slag produced at steel melting shop is known as steel slag. Slag output obtained during pig iron and steel production is variable and depends mainly on composition of raw materials and type of furnace. Typically, for ore feed containing 60 to 65% iron, blast furnace (BF) slag production ranges from about 300 to 540 kg per tonne of pig or crude iron produced.Lower grade ores yield much higher slag fractions, sometimes as high as one tonne of slag per tonne of pig iron produced. Steel slag output is approximately 20%, by mass, of the crude steel output.
Slag crushing plant for sale
Blast furnace slag is being broken by crushing equipment and further grinded by the key grinding mill. Blast furnace slag crusher and grinding machine is also widely used for crushing cement, Portland products, new building materials, refractories, fertilizers, as well as black and non-ferrous metal processing industries such as the production of glass ceramics, various ores and other materials may be grinding of dry or wet grinding.
