Abstract

Sludge dewatering and drying assembly comprises: (1) a helical centrifuge in which the sludge is mechanically dewatered to form a sticky mass with a high residual water content, (2) a drying assembly into which the particles are ejected and exposed to vigorous agitation in hot gases resulting in the formation of smaller particles which form a dry particulate bulk solid. The dispersed particles are pre-dried by hot gases before they come into contact with the walls which are kept free of encrustation by baffles and blades generating turbulent gas flow.
