Abstract
The present invention relates to a screw conveyor configured to produce oxidized wet beaded carbon black including a reaction chamber and at least one ozone inlet to supply ozone to the reaction chamber. It has been found that the destruction of carbon black beads can be reduced using a screw conveyor for the oxidization. Additionally, the oxidation of the wet beaded carbon black could be improved.
