“…In order to verify the model, several empirical equations reported by Musienko, Schmitt, and Purwanto et al, as shown in Table , were used to predict the slag droplet diameter in this evaluation. The calculated results and the measured results based on the experimental conditions are shown in Figure .…”

As the main by‐product in the iron‐making process, blast furnace slag (BF slag) contains a high amount of sensible heat which is a potential heat source with great value if treated properly. Although several technologies have been investigated during recent decades, few of them can be commercialized successfully. In the previous study, we developed a rotating multi‐nozzle cup atomizer (RMCA) for granulating the molten slag. The particle size distribution of the produced slag particle is narrow, the shape is spherical, and the degree of non‐crystallization is over 95%. In the current study, the models of the disintegration mechanism, the traveling trajectories and the temperature profile of the slag droplet are established. The particle size is analyzed theoretically and then compared with experimental results. It is found that the predicted results agreed with the experimental results very well. The models can provide guidance for designing commercialized atomizer and optimizing the operation parameters.

“…The undissolved part (ogarok) makes up 20 -30% of the original raw material and is directed toward mixed metal waste production. According to an estimate, the amount of unconventional (particle) size can reach 30 to 40% of the total installed capacity [9]. Was performed detailed analyses at selected companies in Russia and found that during the gas cleaning processes in the above operations, the loss is up to 5% of the total volume of powder produced.…”
