Advanced Material Roasting

AMG Vanadium offers roasting of metal-bearing industrial materials at our Cambridge, Ohio headquarters.

Our multiple-hearth roaster contains eleven hearths (or floors) stacked on top of each other. Material is fed into any of four locations in the roaster, and then transferred mechanically via a center shaft, arms and blades to lower hearths (or floors). These components move the material alternately inward (towards) and outward (away) from the center shaft. At the bottom of the roaster, material is cooled and mechanically conveyed into pneumatic trailers. This intermediate product can then be packaged as-is, or briquetted on-site.

The roaster processes materials at temperatures up to approximately 1800° F (1000° C). The reactions available include removal of sulfur, carbon, water and oil. Feedstocks are often blended for metallurgical and logistical considerations, but we can isolate quantities as small as 500 tons if desired by the customer. Capacity depends on raw material composition and form, but ranges up to approximately 25K tons annually.

The effluent/gas/exhaust train includes a multiclone to maximize recovery of the metals-containing materials and a dry flue gas desulfurization (FGD) unit that allows for processing of higher sulfur-containing materials. The sulfur dioxide is converted to a calcium-sulfur oxide that has commercial applications. This environmental system is consistent with our commitment to producing no wastewater stream.

Our roasting capabilities feature the most productive, flexible, cost effective and environmentally friendly processing available. Contact Customer Service at 740-435-4639 to discuss processing of your material.
