The Feasibility of Air Classification of Dusts from the

Air classification could be used in a similar way for the residues from dry off-gas de-dusting. However, the costs are expected to be higher for air classification compared to classification in hydro-cyclones because an air classifier is a much more complex and expensive machine compared to a hydro-cyclone.
