Each slag
Pool of slag by the spiral machine quickly upgrade to dried in a dryer, and then transported by belt conveyor to the implementation of the separation of scrap tailings after magnetic separator. Return steelmaking production over 1mm steel particles less than 1 mm steel powder used as a sintering flux tailings as a building material.

Magnetic Drum Separator Dings Magnetic Drum Separator is a permanent selfcleaning separator designed for heavyduty, highvolume ferrous recovery. Its rugged contruction is ideal for separating ferrous metal from material such as shredded cars, slag, crushed ore, and ash at mass burn plants.
Crushing and magnetic separation Steelmaking slag contains about 10 40wt% metal iron (exclud ing iron oxides), which is derived from the refining process or from some processing vessel (, the converter, hot metal/molten steel ladle, or tundish).
tO content in slag on phosphorus separation from steelmaking slag, steelmaking slags were reduced by carbonaceous material at high temperature by using an induction furnace. From the results, the effects of slag composition, temperature and oxygen partial pressure on phosphorus separation from steelmaking slag were discussed.
Alibaba offers 43 steel slag magnetic separator products. About of these are mineral separator. A wide variety of steel slag magnetic separator options are available to you, Steelmaking slag beneficiation by magnetic separator doiSerbia. Steelmaking Slag Beneficiation by Magnetic Separator and. Impacts on Sinter Quality. Ö. S.
Results show that nearly all the phosphorus was enriched in the C2S phase in the modified slag which was separated into two layers, top and bottom (termed as modified slag1 and slag2), after solidification. The P2O5 in the nonmagnetic materials from slag1 is greater than 4%, which is .
Counting with the slag/steel ratio of 140 kg/ ton steel, the annual slag production of various types can reach 910,000 tons. Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel built 12. closed and tanktyped containers, which can be used for molten BOF slags to subject to water quenching.
steelmaking slag using a magnetic separation system . MgO, MnO, Na2O and CaF2 have little effect on the phosphorus recovery whereas SiO2, Al2O3 and TiO2 have great effect on phosphorus enrichment in slag and magnetic separation.

Steelmaking Slag Beneficiation by Magnetic Separator and Impacts on Sinter Quality Ö. S. Bölükbaşı1, B. Tufan1* 1Department of Mining Engineering, Dokuz Eylül University, 35160, Izmir, Turkey Abstract: Basic oxygen furnaces (BOF) slag is the main problem at all iron and steel factories.
weak magnetic separation with selective size screening on steelmaking slag fines. This fractioncouldbe consequently senttodifferent unit operations of ironmaking and steelmaking route, increasing the recycling rate of slags (Ma et al. 2014), or classified as a recyclable not hazardous waste.
In the last years, it had been supplied several equipments of magnetic separation for plants only dedicated to the treatment of steelmaking slag.
Ore smelting. In this case, the slag is termed synthetic. A good example is steelmaking slag: quicklime and magnesite are introduced for refractory protection, neutralising the alumina and silica separated from the metal, and assist in the removal of sulfur and phosphorus from the steel.
BOF Slags. Different kinds of slags arise during the steelmaking process. During the oxygen blow, impurities in the metal (carbon, silicon, manganese, and phosphorus) as well as some iron are oxidized to form the largest portion of the steel slag, the socalled primary slag.
Magnetic Separator Manufacturer of a wide range of products which include wet drum magnetic separator, drum type magnetic separator, magnetic roll separator, triple drum type magnetic separator, magnetic coolant separator and belt type permanent magnetic separators.
The slags with particle size of 10 mm were enriched by the magnetic separator resulting and increase in Fe grade from 18% to 33%. The use of BOF slag in sinter blend provided additional Mn, CaO, MgO and introduced a good solution to environmental problems.

Magnetic separation was applied to the recovery of manganese and phosphorus from dephosphorization slag. Dephosphorization slag consists of phosphorus enriched phase and manganese enriched phase together with matrix phase. The magnetic property of each phase has found to be significantly different.
The task of steelmaking slag recycling presents a particular difficulty (Das et al ., 2007; Ma and Houser, 2014), first of all, due to the ... magnetic separation (Alanyalı et al ., 2006). However, it is known that not all iron compounds are highly sensitive to the magnetic action. So a material part of potentially
