Beschreibung
Zusammenfassung:	Iron-aluminium garnet ore is used as raw material through the process of material selecting, disintegrating, grinding, chemical treating, drying over a fire and dry classifying to prepare a fine abrasive powder which can be in different granule-diameter. Adapted equipment includes grinding machine, separator and classifying device. Said classifying device divides the fine powder into sections according to the law of that the fine powder subsides uniformly along with its weight gradually reduces to obtain fine power of different granule-diameter. Advantage: saving energy-source.
