However, in the production and processing of carbon black, magnetic impurities such as iron filings and metal particles are often mixed in the raw materials. These impurities not only affect the purity of carbon black products, but also can cause wear and tear to the equipment in subsequent processing links, exacerbate equipment wear and tear, and even cause production failure. In addition, the presence of these magnetic impurities can also interfere with the performance of carbon black products, for example, in the application of conductive materials or high-performance coatings, magnetic impurities can cause unstable product performance, seriously affecting the quality of the final product. Therefore, efficient separation of magnetic impurities in carbon black has become an important link to ensure the quality of carbon black products and production stability.

[0003] In the prior art, for the separation of magnetic impurities in carbon black, a magnetic separation device is often used. Magnetic separation technology utilizes the attractive force of a magnetic field on magnetic substances to effectively separate impurities such as iron filings and metal particles from carbon black. However, traditional magnetic separation devices have certain technical limitations in practical application. First, these devices have high requirements for the uniformity of carbon black particles.
