Slag is discharged during steelmaking, usually dark and dark brown. By steelmaking furnace slag can be divided into flat slag, electric furnace slag, Slag is mainly content calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus and other oxides. It is a large displacement of industrial solid wastes, discharged crude steel production is about 15% -20%.


Slag utilization methods, according to the characteristics of slag and finished requirement, you can choose to use crushing screening equipments, iron removal equipment and grinding equipments for processing them, and according to the requirements to process into different granularity. The pre-crushed slag, baked dry, magnetic screening, crushing, grinding grading, wet magnetic separation grading, pellet manufacturing and other processes.

1. Pretreatment. There are some raw slag particle size exceeds the maximum feed size, which requires the use of tools such as hammers pretreatment to meet the processing equipment requirements.
2. Crushing and screening. Using jaw crusher, cone crusher and vertical shaft impact crusher and screening equipments, the raw slag material through crushing and separation, and ultimately to a certain particle size for building materials or further processing.
3. Iron removal. In the crushing and screening process, cone crusher and vertical shaft impact machine are all iron forbidden through. The iron is the more valuable components of slag. Iron removal equipment be installed not only to ensure the normal operation of equipment, but also bring huge economic benefits.
4. Grinding. Crushed and magnetic materials, using MTW European trapezium mill for further grinding, you can get different fineness materials, which can be used in brick, cement and concrete making.



Slag processing equipments can supply crushing, magnetic separation, separation, grinding and other deep-processing. First isolated particles can be melted steel making, the rest of the coarse particles used as motorways gravel aggregate material, crushed into fine slag powder can be elected iron powder, the rest was used for cement and concrete admixtures high activity , washed down mud bricks can produce slag brick, steel slag processing achieving a "zero emissions."
