Abstract
Abstract FLUFFY PARTICLES OF THE CARBON BLACK ARE VIOLENTLY AGITATED IN COMIXTURE WITH A MICRO-ATOMIZED FOG OF OIL PARTICLES AND THE AGITATION IS CONTINUED UNTIL THE CARBON BLACK PARTICLES ARE UNIFORMLY COATED WITH OIL. THEREAFTER, THE OIL COATED PARTICLES ARE RECOMBINED INTO A BED AND PELLETIZED BY MEANS OF A RELATIVELY MILD TUMBLING ACTION. THE RESULTANT PELLETS ARE USED IN PRINTING INK FORMULATIONS, E.G. NEWSINKS.
