Project Overview and Background:<\/strong><\/p>

Carbon black is an essential industrial raw material widely used in rubber, plastics, inks, coatings, and emerging new energy battery applications. In high-performance fields\u2014especially specialty coatings and conductive materials\u2014extremely fine particle size distribution is crucial. Precise control of product fineness (such as D97 values) directly determines end-product performance.<\/p>

This case project is located in Iraq, where the customer required ultrafine grinding and precise classification of a specific carbon black feedstock.<\/p>

Core Requirements and Challenges<\/h2>

Ultrafine Particle Size Target<\/strong><\/p>

The final product needed to reach D97 = 10 \u03bcm.
For carbon black\u2014a material with strong agglomeration tendency and large specific surface area\u2014achieving such ultrafine grinding and tight particle size control imposes high demands on grinding efficiency and classification accuracy.<\/p>

Throughput Assurance<\/strong><\/p>

The customer required a stable production rate of 250 kg\/h, ensuring continuous operation and economic productivity.<\/p>

Material Characteristics<\/strong><\/p>

Carbon black is lightweight, easily airborne, and prone to agglomeration. These characteristics challenge equipment sealing performance, dust control, explosion protection (if flammable grades are involved), and maintenance cleanliness.<\/p>
