The Mikro ACM air classifier mill, operating in the medium to fine size reduction range, delivers precise particle size due to variable-speed integral air classifier, and attains the smallest amount of ultra fines with a steep particle size distribution. It has been continuously improved and adapted to suit wide range of products, even in processing difficult-to-handle materials.

The Mikro ACM operates on the impact grinding principle. It uses high rotor speeds with a striking edge velocity of up to 120m/s. By striking material particles on the grinding track, fixed liner, or rotating grinding surfaces such as pins or hammers, particle sizes can be reduced. The air classifier mill uses variable classifier speed to precisely control the particle size, cut point, and distribution.

Key Features

The key features of the Mikro ACM air classifier mill are:

  • Classifying and grinding in one unit
