Abstract

The invention relates to a process for producing hybrid carbon black particles (12), which comprises the steps: a) production of first carbon black starting particles (16); b) production of second carbon black starting particles (22); c) milling of the second carbon black starting particles (22); d) mixing of the second carbon black starting particles (22) into a particle stream (48) of the first carbon black starting particles (16); and d) pelletization of the first and second carbon black starting particles (16, 22) to form hybrid carbon black particles (12). The invention further relates to an apparatus (10) for producing hybrid carbon black particles (12) and to hybrid carbon black particles (12) produced by means of the process or the apparatus (10).
