Description

Technical Field

[0001] The invention relates to the technical field of carbon black production, and in particular to a carbon black recycling device and a control method for carbon black production. Background Art

[0002] Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. It is mainly composed of carbon and contains a small amount of elements such as oxygen, hydrogen and sulfur. Carbon black particles are approximately spherical, with a particle size between 10 and 500 μm. Many particles often fuse or agglomerate into three-dimensional bonded dendrites or fibrous aggregates. In rubber processing, it is added to rubber through mixing as a reinforcing agent and filler. The carbon black re-mixing device is a device specially designed for carbon black production, aiming to improve production efficiency and product quality.
