Abstract

Abstract: The measures for producing high quality pellets from Daye iron concentrate are found through pelletizing test. The test result indicates that when using a Daye iron concentrate which contains 93.35% -0.074 mm fraction, 2% Linan betonite as binder and 8.0% moisture, through strict control of the pelletizing time and the material and water feeding rate and mode, fine quality pellets can be produced. The green balls have a drop strength at 0.5 m greater than 3.8 times, a compressive strength of 12.0 N per ball and a burst temperature of higher than 450 ℃. The compressive strength of the pellet product is greater than 2.5 kN per pellet.

Key words: Daye iron concentrate, Pellet, -0.074 mm fraction content, Benotite dosage, Moisture
