The present invention relates to a method for controlling the oxidation of wet beaded carbon black in a screw conveyor. It has surprisingly been found that the motor current used to drive the conveyor screw is an indicator for the destruction of the wet beaded carbon black during the oxidation. The inventive method as well as control device utilize said motor current and adepts the rotational speed of the screw.
