Air classification - Import export

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.

The SMA is a mechanical airclassifier, autonomous equipment designed to separate a material of intermediate fineness (0 to 5 mm for instance) or a ground product (0 to 1 mm or less) into two fractions of different finenesses one fine fraction (particles from 0 to 40 microns up to 500 microns); one coarse fraction (from 40 microns to 5 mm for instance). This air classifier can be used either as a classifier operating in an open circuit (for extraction of natural raw material like sand for instance) or in a closed milling circuit, to control the fineness of ground product or to "preclassify" when the classifier is placed after the air separator and grinding oversize only.
