Mikro ACM Air Classifying Mill

Mikro Air Classifying Mills (Mikro-ACM®) which was invented by HMPS in the late 1960’s is one of the most versatile size reduction equipment available in the market. These units while being capable of producing fine, medium and coarse grinds for wide variety of materials for Food, Pharma, Chemical and Mineral industries require very little maintenance over their life span. The basic concept of these mills is the impact size reduction that is coupled with an internal dynamic classifier which will control the outlet (product) particle size via recirculating the coarse back into the grinding zone.

There are seven main factors which determine particle size distribution for the Mikro-ACM® Mill. When varied, the rotor type and speed combined with the liner and hammer count affects the production of fines. The separator type and speed affects the top size of the product. And lastly, the airflow governs the throughput as well as top size and fines generation. With the endless available options can be configured to process just about any material that is below MOH’s hardness of 5.
