ABSTRACT:
An apparatus for drying pellets of particulate material such as carbon black is characterized by a columnar drying vessel containing inclined trays or screens positioned so that the pellets or particulates roll from screen to screen down the column. Preferably, the pellets are subjected to countercurrent flow of drying gases while flowing down the screens. In other aspects, carbon black is pelleted with a nonaqueous liquid pelleting fluid and dried with vapors of the same pelleting fluid.
