ABSTRACT:
Wet pellets of carbon black are dried to produce dry pellets by means of a two-step process. In the first step a bed of wet pellets is fluidized by means of a heated gas and the pellets are thus partially dried. In the second step the partially dried pellets from the first step are subjected to additional drying while in a nonfluidized state, e.g. pellets from the fluidized bed are heated and subjected to a mild, mechanically produced tumbling action during the second step.
