Fine milling - Import export

The MA (or Hammer mill) is an impact grinder that crushes the input material between the hammer (or knife) plate and a stator fitted with a sieving screen perforated for the required particle size. It is generally used as a pregrinder positioned upstream of a grinding installation. The MA breaks up blocks of raw material into smaller particles capable of being treated by a mill for fine grinding.

The MICRODYN is an abbreviation of the words "MICROclassificateur DYNamique". It is composed of one or several variable speed classification rotors, clean air for rinsing and a waste discharge spout. It is particularly effective for the production of very fine powder from a pulverulent produced by an existing grinding process. It is fitted as standard on the PAS Integrated Classifier mills. The fine particles are transported by the pneumatic circuit towards a finished product collector (cyclone or filter for finer products). The oversized particles are evacuated out of the circuit along a skirt or through a rotary valve.
