The Mikro® E-ACM is specially designed for the grit reduction of carbon black. Many of the same design features of the Mikro ACM® Air Classifying Mill, a workhorse in the industry for a wide array of applications for decades, have been integrated as the basis for design of the Mikro® E-ACM. In addition, various improvements have been made to overcome the challenges of milling carbon black.

Unlike standard air classifying milling operation, the carbon black feed material is fed in the primary airstream from below the rotor of the Mikro® E-ACM. The internal parts and geometry of the grinding and classification sections have been modified to meet the particle characteristics and quality specification of carbon black. In addition, the internal recirculation working principle of the air classifying mill has been replaced with our patented external coarse recycle system. All these enhancements yield low product grit levels other milling technologies cannot achieve.
