A Mathematical Model for Air Atomization of Molten Slag Based on Integral Conservation Equations

This work is motivated by the industrial process of air (or dry) atomization of slag, where a high-speed jet of air impinges onto a free-falling stream of molten slag and disintegrates it into small droplets. The droplets solidify to form slag powder particles which may be used in applications such as sand blasting, roof shingles, and asphalt. Since different applications require slag powders with different ranges of particle size, controlling …
