Slag often contains valuable metals that can still be recovered and utilized. When crushed and sized properly, slag can be sold and used as valuable material in many different ways, for example, as aggregates. However, since slag usually contains uncrushable objects, it is typically considered a challenging feed material for conventional jaw ...
Applications. 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 …
The D50 of untreated steel slag could only reach 32.89 Mm after 50 min grinding, but that of pretreated steel slag could reach 18.16 after the same grinding time.
nickel slag samples with crushing and sieving up to 200 mesh. The nick el slag is then reduced at . 800 0 C, 900 0 C an d 1000 0 C temperature without adding sodium sulfate and by adding sodium . Grinding, sieving and magnetic separation were combined to recover metallic iron from the converter slag, and yielded approximately 41.5% of iron in ...
Crushing and Sieving. When a sample arrives it is first crushed and sieved. This is to obtain the correct grain size for the rest of the separation process. The ideal grain size is 0.25-0.50mm. There are two crushing machines available; a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the ...
The ideal grain size is 0.25-0.50mm. Clean the jaw crusher and pulverizer thoroughly with pressurized air and a wire brush. Be sure to clean the catch trays for both the crusher and the pulverizer. Set the crusher jaws about half a …
Slow cooling (air cooled), crushing, sieving: Concrete and road aggregate: Crystalline, density, strength: GBS a: 30–45: 30–40: 10–15: 5–15: 0–1: ... BOS slag is decanted off from the surface of the molten steel and is normally cooled slowly, by air-cooling or water quenching, in pits or bays prior to being dug and transported to ...

Fig. 2(b) shows the slag after crushing and sieving. The crushed slag was used as a flux to prepare an 8 layer high weld pad as per the schematic shown in Fig. 3, to get undiluted weld metal free from the effects of the base plate on the top layer, in accordance with ASME SFA5.9/5.17 specifications. Boiler grade high strength low alloy ...
The same is with Basic Oxygen Furnace (BOF) slag. Processing of EAF using traditional methods involves crushing and grinding. However, the new technology of atomising molten slag is an innovative process that produces high-specification products with multiple uses. ... PS balls are classified by size through a sieving machine. The main …
