Abstract: A continuous drying process for powdered lampblack, comprises: (i) passing the lampblack through a helical granulator assembly which is formed by a helical sequence of metal quills whose maximum tip speed is 1-6 m/s; (b) allowing an average residence period for the powder of 20-600 seconds; (c) inoculating the raw incoming lampblack with 50 % preferably 5-30% granular lampblack (9); (d) pre-compressing the raw incoming lampblack to 150-300 g/l; and (e) using a dry pearl drum after the helical granulator.

Abstract: Furnace black (I) has a hydrogen (H) content of over 4000 ppm, determined by CHN analysis, and peak integral ratio less than 1.22, determined by inelastic neutron scattering (INS) of unconjugated H atoms (1250-2000 cm ) to aromatic and graphitic H atoms (1000-1250 cm and 750-1000 cm ). An Independent claim is also included for the production of (I).

Abstract: The present invention relates to a process for continuous dry granulation of powdered carbon black. Granulation is carried out with the assistance of a granulator. As a result, for comparable sized equipment, the carbon black throughput can be increased several times as compared with pelletizing drums used in the conventional manner. The manufacturing process is characterized in that granulation is carried out within a granulator the shaft of which is provided with pins, wherein peripheral speed of the ends of the pins ranges between 1 to 6 m/s and an average residence time for the carbon black in the granulator ranges within 20 to 600 seconds. Space between the ends of the pins and the stator wall is preferably from 0.5 to 3 mm and granulation temperature is in the range of about 50 to 150 degC.

Abstract: Carbon black beads, which contain natural and/or synthetic wax and are produced by granulating carbon black powder, have a wax content of 1 to less than 10 wt.% and a hardness greater than 0.15 N. An Independent claim is also included for the continuous production of the beads. The beads are produced in a heated granulator with a toothed shaft and inlet, granulation and outlet zones. The carbon black powder is fed into the inlet zone. Molten wax or wax mixture with an average droplet size NOTGREATER 50 micron is sprayed into the first third of the granulation zone. The shaft operates at a maximum peripheral velocity of 1-6 m/s and the average residence time of the carbon black in the machine is 20-600 seconds.
