3 Phase Disc Stack Separator Disc Stack Separator GN 3 phase disc stack separator is a high-speed, stable, sealed, efficient, and automatic slag discharge 3 phase separation equipment. It is widely used for liquid, liquid, solid 3-phase separation or liquid-liquid separation.

Mobile Eddy Current Separator Magnetic separation. The Eddy Current separator uses a strong magnetic field to separate non-ferrous metals from waste. All ferrous metals are previously removed by an arrangement of magnets. Eddy currents, which are created by an rapidly rotating magnetic rotor, affect the trajectory of non-ferrous metals.

12%The temperature was maintained for half an hour thus permitting slag and melt separation. When the mixture commenced melting, the melt was stirred two or three times by a quartz tube. After melting separation, elemental Ni and Co were transferred into the metal phase, whereas oxidized RE, Al and Mn were transferred into the slag phase.

The effective STEINERT separation solutions for dry mechanical processing of waste incineration slag. In Germany alone, more than 5 million tonnes of ash are created each year from the energetic usage of municipal solid waste.

slag and weld metal. The slag appears embedded into the steel matrix and a separation of particulate matter from the slag which might contaminate a flowing medium seems to be very unlikely. 4 Conclusions For the slag spots we investigated it can be concluded that a detrimental effect on the flowing medium inside the tube system seems very ...

of phosphorus and separation of iron and slag. Hence, the effect of the temperature and time of melt separation, basic-ity of slag, addition of CaF 2 and the metallization ratio of reduced fines were investigated to evaluate the feasibility of the process of H 2 reduction followed by the slag/metal separation for oolitic hematite ore.

Different methods of separation are used to get individual components from a mixture. Separation makes it possible to study and use the individual components of a mixture. ... Take some full-cream milk in a test tube. ... the lighter slag is removed from the top by this method to leave the molten iron at the bottom in the furnace.

The efficiency of matte smelting and matte-slag separation, as well as the extent of copper losses to slag are mainly affected by the oxidation/reduction potential, matte grade, smelting temperature, slag composition, and slag properties (Deng and Ling, 2007; Najimi et al., 2011). For example, silica as the main slagging constituent is ...

The Cost of Slag. Cutting Through the Buildup: The time and money associated with managing slag is often mistaken as an unavoidable cost in laser cutting operations. But once you realize the full impact that slag has on your laser cutting process, there are ways to cut costs . . . by cutting through the slag. Posted: October 24, 2013. Figure 1.

Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.

Guo adopted the melt separation of hydrogen-reduced, high-phosphorous iron ore powders at 1823 K (1550 °C) and realized the effective separation of molten metal and slag, but the phosphorous content in the metal phase was up to 1.22 wt pct, which means that all of the phosphorus in reduced ore has migrated into the metal.

Your Advantages In Processing Oils Sludges From Ponds And Lagoons: Approx. 90% of the oil contained is recovered and can be recycled as crude oil. The separated solid is only approx. 10 - 20% of the original quantity of sludge. This reduces transport, landfill and incineration costs significantly.

After 30 min, the SiO 2 tube containing the slag pellet was quickly introduced into the 0.5 wt%Al–99.5 wt%Si melts, and the melts flew into the tube through the hole and contacted the slag pellet. After contacting for a predetermined time, the Si and slag in the SiO 2 tube were pulled out and were quenched in water rapidly.

Water-quenched lead slags are classified as hazardous materials because they contain a certain amount of heavy metals.
