Why is Electric Arc Furnace (EAF) Dust so difficult to convey?
The EAF dust generated in a combustion process by electric arc furnaces employed in steelmaking is a hazardous material containing many heavy metals such as lead, cadmium, zinc, etc. These materials are not only hazardous requiring safe and reliable methods of conveying and disposal but they are also highly abrasive and poorly flowing. Furthermore EAF dust can have high moisture content. As a result EAF dust is a challenge to convey and special considerations must be applied to the way the material is fed as well as conveyed. The best way to convey EAF dust is using dense-phase pneumatic conveying which has the ability to convey EAF dust reliably with an added benefit of minimizing pipe wear.by
