The characteristics of carbon black vary depending on manufacturing process, and therefore carbon black is classified by manufacturing process. Carbon black produced with the furnace process, which is the most commonly used method now, is called “furnace black,” distinguishing it from carbon black, which is manufactured with other processes.
Furnace Black Process
This method forms carbon black by blowing petroleum oil or coal oil as raw material (feedstock oil) into high-temperature gases to combust them partially. This method is suitable for mass production due to its high yield, and allows wide control over its properties such as particle size or structure. This is currently the most common method used for manufacturing carbon black for various applications from rubber reinforcement to coloring.
Channel Process
This method forms carbon black by bringing partially combusted fuel, which is generated with natural gas as raw material, into contact with channel steel (H-shaped steel) and then collecting the carbon black which results.
There are yield and environment issues around this method, and therefore has lost the leading role as the mass production process to the furnace process. This method, however, provides carbon black with many functional groups on the surface, being used in some painting applications.
Acetylene
Black Process
This process obtains carbon black by thermally decomposing acetylene gas. It provides carbon black with higher structures and higher crystallinity, and is mainly used for electric conductive agents.
Lampblack Process
This method obtains carbon black by collecting soot from fumes generated by burning oils or pine wood.
This method has been used since the days before Christ, and is not suitable for mass production. However, it is used as raw material for ink sticks as it provides carbon black with specific color.
Carbon Black Manufacturing Process Plant
The Carbon Black Manufacturing Process Plant mainly consist of hammer crusher , main unit, Frequency conversion classifier, powder collector, pulse dust cleaner,high pressure positive blower, air compressor, muffler, electrical apparatus control system, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler. -
