Abstract
A method and apparatus is disclosed for maintaining the uniformity of a mixed dust slurry stored in a basin, the mixture comprising blast furnace dust slurry, steel furnace dust slurry (defined in the specification) and, if necessary, dry dust or filtrated cake and having a relatively high concentration -- 32% by weight or more -- of solids. The mixture in the storage basin is stirred or agitated by injecting gas or the liquid to be used in the mixture itself into the basin. The method and apparatus are utilized as a part of a system for manufacturing reduced pellets from the dust discharged in an iron foundry or steel mill.
