摘要：
The invention relates to carbon black granulates having an APC value, measured at a conveying speed of 8 m/s and a solid load of 27 g/kg, less than or equal to 20 and a 25 [mu]m pressure filter value of less than 5 bar cm2/g. The carbon black granulate is produced by carbon black powder being pre-granulated in a first mixing granulator with addition of a granulation liquid with or without binders and being granulated to a finished state in a second mixing granulator without further addition of granulation liquid. The carbon black granulate can be used as a filler, reinforcing filler, UV stabilizer, conductive carbon black, pigment, or reducing agent.
