16.04.2018 Aumund to supply HBI cooling lines to Cleveland Cliffs

In December 2018 Aumund Fördertechnik, Germany, will despatch an HBI evaporation cooler system to Cleveland Cliffs, the operator of a hot briquetted iron (HBI) plant in Toledo, Ohio, USA. Aumund’s patented technology consists of two FPB-K pan conveyors with centre distances of 72m. Cleveland-Cliffs Inc. is constructing a new HBI works at this location close to Lake Erie.
The greenfield project will utilise the existing port infrastructure on Lake Erie, and MIDREX was selected as general contractor to supply the direct reduction plant. Aumund, as subcontractor to MIDREX, is supplying one of the most important elements of the whole process, the HBI cooling lines. The decision-makers involved in the project have given their vote of confidence to the evaporation cooling process patented by the German manufacturer. In this HBI-slow-cooling process, the HBI product to be conveyed is cooled from 750o to 90oC in a process which protects the integrity of the product. Aumund guarantees a handling throughput of up to 285t/h at a nominal conveying capacity of 142t/h.
The first installation of its kind was successfully completed by Aumund in Venezuela in 2006. After this pilot project, the company won further HBI orders in Russia and the USA “Today, after constant optimisation of details, the technology has reached such a state of maturity that both operators and general contractors increasingly favour the AUMUND solution over traditional methods”, said Matthias Moritz, the company’s sales director metallurgy. Cleveland Cliffs Inc. is one of the largest iron ore producers in the USA, with mines and pelleting plants in Michigan and Minnesota, as well as in Western Australia.
