Abstract：The principle of the fluidized hydrocyclone concentrator was analyzed and the classifying experiment for titanomagnetite ore in Panzhihua was carried out. The results showed that the particle size distribution of settling sand were effects by feed concentration, feed pressure, injection water pressure, overflow pressure and underflow pressure greatly. Under the conditions of feed concentration 5%, feed pressure 70?72 kPa, water injection pressure 5 kPa, overflow pressure 40?50 kPa, underflow pressure 45?55 kPa, the distribution rates of settling sand of 0.15?2.00, 0.074?0.15 and less than 0.074 mm were 80%?83%, 60%?65% and 20%?28%, respectively.
