经过多年的努力,梅山冶金公司烧结厂已使梅山精矿粉的配用量逐年提高。但由于梅山精矿粉粒度细、软化温度低,使配用后垂直烧结速度降低;而梅精粉粘性大的特点又使梅精粉团块在混合时不易散开,使烧结矿产生“夹馅”,导至成品率下降。这一切使 After years of hard work, Meishan Metallurgical Company Sintering Plant has made the use of Meishan concentrate powder increased year by year. However, due to the fine grain size and low softening temperature of Meishan concentrate powder, the vertical sintering speed is reduced after the blending. The large viscosity of the plum powder also makes the plum powder agglomerate difficult to disperse during mixing, resulting in “clip Stuffing ”, leading to decline in yield. All this makes it
