The manufacture of GGBS mainly involves the processes of cooling of molten slag through high-pressure water jets, drying, and grinding in a rotating ball mill [5, 9]. These operations consume less energy as compared to the clinkering process of …
smelting furnace slag often contains 1–2 % copper, and ... time is needed for grinding the slag. Therefore, the slag sample with a 50 % solid was ground over larger periods of
Steel slag is the by-product during the separation of molten steel from impurities in the steel-making furnace. The basic oxygen furnace slag, electric arc furnace slag, and ladle furnace slag are three major types of SS produced in the steelmaking processes.As drawn in Fig. 2, BOF slag and EAF slag are both produced during the first refinement of steel (Humbert and Castro …

The self-returning device is located in the revolving part of the mill, and the material forms a self-circulation in the revolving part of the mill through the self-returning device, discharging the qualified material from the mill, leading the unqualified material back into the revolving part to participate in the grinding operation.
Basic oxygen furnace (BOF) slag is a main byproduct produced during the converter steelmaking process. The poor grindability of BOF slag limits its added-value application. In this paper, the grinding characteristics of unmodified and reconstructed BOF slag were compared. Additionally, the grinding property of reconstructed steel slag was also …

During steel production, the impurities in the hot metal react with the fluxes forming the steel slag. Chemical constituents of this steel slag (SS) are relevant to iron/steelmaking or blended cement manufacture. Harmful impurities present in it, however, limit its recycling to these applications. Japan, Europe, and the US consume a significant amount of …

Molten slag is also granulated, by allowing the stream to fall upon inclined plates or revolving drums, which are kept cool. This method has been used to a moderate extent in Germany. It is necessary to pass the granulated slag under a strong magnet in order to remove any particles of metallic iron.
