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."

The working principle of jaw rock crushers for sale is: when the stone crushing equipment works, motor drives belt and pulley to move, and the eccentric shaft drives the mobile jaw plate. When the mobile jaw plate rises, the angle between elbow plate and mobile jaw plate becomes larger.
Steel Slag crusher and Steel Slag grinding mill are used to processing Steel Slag to small size or slag powder, then the material can be use in deep processing industry. Slag properties vary greatly, it is subject to charge, smelting of steel and method of operation, and many other factors. Slag by smelting process can be divided into: the initial slag, slag, poured steel slag. Some of the latter three collectively known as the late slag slag. Slag by morphological distinction are: water quenching granular slag, slag and powdered slag lumps.
Slag utilization range, generally based on its chemical composition. Calcium oxide content of cement with high slag suitable; calcium oxide, magnesium oxide and high iron oxide content of slag and iron in the production of sintering use; phosphorus pentoxide to produce a high content of phosphorus slag.
Slag grinding equipment is the necessary equipment inslag treatment process. Common slag grinding equipment including slag crusher and slag mill. There slag crusher jaw crusher, impact crusher, cone crusher, mobile crusher. There slag mill ball mill, Raymond mill, vertical mill, jet mill and so on. Kefid machinery is a professional production crusher and milling machine manufacturers, and its products have been exported to the world more than 180 countries and regions. Many manufacturers have chosen Kefid slag processing crusher and grinding mill equipment as slag.

Steel slag mainly comes from the oxidation of elements contained in the molten iron and scrap; metal impurities; the slag agent such as limestone, fluorite, silica, as well as oxidants, desulfurization products and the erosion of lining materials.
The main components of steel slag are calcium, iron, silicon, magnesium, aluminum, manganese and phosphorus oxides. The main use of the slag are as follow. First, it can be instead of lime as a solvent to return the blast furnace or sintering furnace within the company itself. It can also be used for roadbed, railway embankment, and as cement raw material, soil, etc.
The steel slag recycling product line is a fully automated production, more scientific and rational, easier to use, greatly improving the productivity of labor. Production line and delivery system installs the dust removal device, effectively reducing the dust emissions. The entire production process is formed by two jaw crusher, a fine break CS cone crusher, five iron, five screening and other components. Because the line has good ability of magnetic separation and recovery of ferrite, the steel production greatly is improved.
Shanghai Zenith mining and construction machinery Co., Ltd. is a high technology engineering group,steel slag recycling equipment is one of our good products.Zenith can according to the needs of your dressing and the actual situation of the mine for you to choose the most appropriate and effective machine. Our company will create a perfect steel slag recycling product line for you.
Steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. This by-product that mainly consists of calcium carbonate is broken down to smaller sizes to be used as aggregates in asphalt and concrete. They are particularly useful in areas where good-quality aggregate is scarce. This research study was conducted to evaluate the mechanical properties and durability characteristics of steel slag aggregate concrete in comparison with the crushed limestone stone aggregate concrete. The durability performance of both steel slag and crushed limestone aggregate concretes was evaluated by assessing water permeability, pulse velocity, dimensional stability and reinforcement corrosion. The results indicated that the durability characteristics of steel slag cement concretes were better than those of crushed limestone aggregate concrete. Similarly, some of the physical properties of steel slag aggregate concrete were better than those of crushed limestone aggregate concrete, though the unit weight of the former was more than that of the latter.Get in Touch with Mechanic
