AUMUND Cooling Conveyor for Hot Bath Material

For defined cooling of bath material AUMUND developed a solution allowing to cool hot bath material from 850°C down to 70° within a time period of 6 hours. When using the point-feeder prebaked (PFPB) technology, anode butts are removed together with a substantial quantity of hot bath material. This fluoride rich material has usually been collected in containers and cooled down naturally. Due to the thickness of the layer of hot material in these containers, there is no guarantee that the bath lumps will cool down below 100°C even after 24 hours of cooling time. However, before further processing, the material must cool down to a maximum temperature of 70 – 80°C, a feature obtained with the AUMUND cooling conveyor.
