1A Manufacturing Process for Iron and Steel

The direct reduced iron is produced by reducing iron ore with reformed natural gas whose principal components are hydrogen carbon monoxide and methane The scrap along with direct reduced iron is then melted in an electric arc furnace denoted EAF hereinafter to produce molten steel which is subsequently processed by the continuous casting machine as mentioned above

How Material Size Directly Affects Size Reduction Energy

· While a jet mill is capable of reducing a particle population s average size by a factor of 1000 it takes a lot of energy to get there As long as the application allows for it other size reduction methods should be used to initially reduce the particle size as much as possible and the jet mill should be used for the final size reduction
