The use of carbon black after grinding and equipment selection
In recent years, the new materials industry has developed rapidly, and carbon black, as a carbon-based new material, has also received widespread attention from the market.
The main component of carbon black is carbon, which has excellent rubber reinforcement, coloring, conductivity and ultraviolet absorption functions, and is used in a variety of industrial fields.
In addition to 40% tire oil, the product of waste tire refining also contains 30% carbon black. The crude carbon black (50-60 mesh) is ground and processed to 325 mesh.
Uses of carbon black grinding
Processed carbon black can be used as a rubber reinforcing agent for the manufacture of automobile tires. It can also be used as a pigment, such as ink, coating, conductive agent for dry batteries, catalyst carrier, and superhard alloy material. About 70% of the world’s carbon black is used in tire manufacturing, 20% is used for other rubbers, and the remaining less than 10% is used in industries such as plastic additives, dyes, and printing inks.
Carbon black grinding process
The production process of carbon black is to send the previously processed carbon black to a carbon black grinding machine for grinding and collecting the powder. Depending on the fineness of the finished product, grinding machines with different finished product fineness can be selected.
The first stage: the large pieces of carbon black are transported to the raw material warehouse by a special vehicle, and then the materials are sent to the jaw crusher by a forklift/manually for crushing, and the crushing is smaller than the feed size of the mill.
The second stage: the carbon black crushed by the crusher is lifted by the elevator to the storage hopper, and the material discharged from the storage hopper is evenly fed to the main machine by the feeder.
The third stage: the qualified products in the grinding process are screened by the screening system and enter the collector through the pipeline. After collection, they are discharged through the discharge valve as finished products, and the unqualified products fall into the main machine for re-grinding.
The fourth stage: the airflow after the purification of the finished product flows into the blower through the residual air duct above the dust collector. The air path is circulated. Except for the positive pressure from the blower to the grinding chamber, the airflow in the other pipelines flows under negative pressure, and the indoor sanitary conditions are good.
