The present invention relates to a screw conveyor for producing oxidized wet beaded carbon black, comprising a reaction chamber and at least one ozone inlet for providing ozone to the reaction chamber. Research finds that the damage to the carbon black beads can be reduced by using the screw conveyor to oxidize. In addition, oxidation of wet bead forming carbon black can be improved. 本发明涉及一种用于生产氧化的湿法成珠炭黑的螺旋输送机，其包括反应室和至少一个向反应室提供臭氧的臭氧入口。研究发现，使用螺旋输送机进行氧化可以减少炭黑珠粒的破坏。此外，还可以改善湿法成珠炭黑的氧化。
