The present work describes systematic investigations into dry granulation of industrial carbon black with special regard to the residence time characteristics, using a continuously operated semitechnical bead‐forming drum. A novel experimental method and a model for the determination of residence time distribution of carbon black in the bead‐forming drum have been developed and very good agreement of model and experiment has been demonstrated.
