Introduction Indirect-fired rotary kiln has a combustion chamber on the peripheral barrel. The heat generated by the combustion of flue gas is transferred to the material through the cylinder. The material is calcined at high temperatures, and the calcined product is discharged from the discharge valve. The exhaust gas is treated or emptied or utilized. The indirect-fired rotary kiln is suitable for the production of various materials requiring indirect continuous heating.

Recycling Steel Dust Zinc-coated galvanized steel scrap is the most widely used feedstock for Electric Arc Furnace (EAF) steel production. World crude steel production reached 1,66 billion metric tons for the year 2014, up by 3.9% compared to 2013 (World Steel Association). Around 26% of crude steel is produced using the EAF technology.

EAF dust is a by-product of the steel production process, and refers to the dust collected during the melting of steel in an electric arc furnace. Global estimates for EAF dust production currently sit between 5 to 10 million tons annually, a staggering amount, considering the steel industry continues to experience rising demand. EAF dust has long imposed significant waste disposal costs on the steel industry, not only because of the volume at which it is produced, but also
