The purpose of dewatering and classification of slag from hard coal combustion is the elimination of slag hydro-transport to disposal lagoons thus reducing water consumption as well as costs of hydro-transport and storage of water-slag or water-ash-slag suspension and of slag aggregates’ production. The developed technology is based on application of centrifugal sieves, enabling not only slag dewatering but also its classification and removal of remaining bottom ash and cenospheres.
