Description

TECHNICAL FIELD

[0002] Carbon black particles are approximately spherical, with particle sizes ranging from 10 to 500 microns. Many particles often fuse or coalesce into three-dimensional dendritic or fibrous aggregates. In rubber processing, carbon black is added through mixing as a reinforcing agent and filler. The particle size of carbon black has a significant impact on its performance and application, directly affecting the blackness, dispersibility, tinting strength, wettability, and other characteristics of carbon black. In the rubber industry, the smaller the particle size of carbon black, the better the strength and wear resistance of the vulcanized rubber filled with it. However, in some applications, larger carbon black particles can provide better elasticity and heat generation performance. Therefore, screening can meet the specific requirements of different application fields for carbon black particle size.

[0003] Chinese patent CN216910424U discloses a conductive carbon black grinding and screening device. The carbon black raw material is first crushed by crushing teeth, then enters the grinding roller for grinding, making the carbon black raw material more delicate and ensuring the quality. The grinding speed of carbon black is accelerated, the productivity of carbon black is increased, the ground carbon black is screened through a screen, and the screen is screened more quickly by a vibrating motor, making the carbon black screening more uniform and improving the screening efficiency while accelerating the detection of whether the carbon black meets the use standard.
