ABSTRACT:
A process for pelleting carbon black is disclosed wherein flocculent carbon black is pelleted in the conventional manner by mixing the carbon black with an aqueous pelleting liquid and stirring the mixture to form water-containing carbon black pellets. These water-containing carbon black pellets are then predried conventionally in order to remove a first major portion of the aqueous pelleting solution therefrom. For the removal of a remaining minor second portion of said aqueous solution, the carbon black pellets are subjected to a microwave irradiation.
