The production of high-performance coatings demands precise control over pigment particle size and distribution. Carbon black, as one of the most important pigments in the coatings industry, requires ultrafine grinding technology to achieve optimal dispersion, color strength, and stability. This article explores the technical requirements for carbon black grinding and presents advanced milling solutions that meet these demanding specifications.
Carbon black particles in the ultrafine range (typically below 5μm) significantly enhance coating performance by improving opacity, UV resistance, and mechanical properties. The selection of appropriate grinding equipment is crucial for achieving the desired particle size distribution while maintaining production efficiency and cost-effectiveness.
High-performance coatings require carbon black particles with narrow size distribution and D97 values typically between 325-2500 mesh (5-45μm). The grinding system must maintain consistent particle size control throughout the production process to ensure batch-to-batch consistency and optimal coating performance.
Carbon black is thermally sensitive, and excessive heat generation during grinding can lead to particle agglomeration and degradation of pigment properties. Effective cooling systems and controlled grinding energy are essential to maintain product quality.
The grinding process must prevent metallic contamination from wear parts, which can affect color quality and coating performance. The selection of appropriate lining materials and design of grinding chambers are critical factors.
For carbon black applications requiring the finest particle sizes and tightest distribution control, we recommend our SCM Ultrafine Mill series. This advanced grinding system is specifically engineered for materials demanding ultrafine processing with superior efficiency and reliability.
The SCM Ultrafine Mill achieves remarkable performance through its innovative design:
| Model | Processing Capacity (ton/h) | Main Motor Power (kW) | Output Fineness (mesh) | Feed Size (mm) |

| SCM900 | 0.8-6.5 | 90 | 325-2500 | ≤20 |
| SCM1000 | 1.0-8.5 | 132 | 325-2500 | ≤20 |
| SCM1250 | 2.5-14 | 185 | 325-2500 | ≤20 |
| SCM1680 | 5.0-25 | 315 | 325-2500 | ≤20 |
For larger production requirements while maintaining ultrafine specifications, the LUM Ultrafine Vertical Mill offers an excellent alternative. This system combines high capacity with precision grinding capabilities suitable for carbon black processing.
Key advantages of the LUM series include:
The SCM Ultrafine Mill demonstrates exceptional energy efficiency in carbon black processing, achieving approximately 30% lower energy consumption compared to conventional jet mills while providing double the production capacity. This significant reduction in operating costs makes it an economically attractive solution for coating manufacturers.
Through precise particle size control and uniform distribution, the SCM series ensures carbon black pigments with optimal characteristics for coating applications:
The specially designed grinding rollers and rings manufactured from wear-resistant materials significantly extend service life in carbon black applications.
