摘要
国内一种细粒级铁矿粉,经高压辊磨预加工后,对其造球性能以及干燥速率的变化进行对比研究。研究结果表明,经过高压辊磨加工,此种铁矿粉生球的性能得以改善,表现为落下次数以及抗压强度得到提高,但生球团矿的干燥速率下降,不利于生球团后期的干燥。
A fine grade of domestic iron ore, pre-processed by high-pressure roller mill, of which the bailing performance and drying rate changes are comparatively studied. The results show that after high-pressure roller grinding, the performance of iron ore powder ball is improved. The fall times and compressive strength are improved, but the drying rate decreases, which is not conducive to later dry the ball.
