Most versatile size reduction equipment available on the market

The Mikro ACM Air classifier mill from Hosokawa Alpine is one of the most versatile types of size reduction equipment available in the market. Size reduction is a result of the feed product impacting against the rotating grinding elements and against the stationary liner. At beater tip speeds of up to 140 m/s, fineness values of d97 = 10 µm are achieved.

The fines pass through the classifying wheel and exit the mill. The cut point is a function of the classifying wheel speed, which can be adjusted even during operation.

The most common applications of the Air classifier mill, are materials for powder coatings, cosmetics, food, pharmaceutical, chemical, and Mineral industries.
