一、前言造球是球团矿生产中一道重要工序,生球质量的好坏,直接影响球团矿的产质量。而原料的粒度及粒度组成,对生球质量起着决定性的作用。因此在国外非常重视原料的准备,特别是原料的磨矿细度。国外球团厂通常在建厂之前,根据原料的性质,经过磨矿与造球等试验研究,以确定最佳的磨矿细度。因为粒度过粗使球团质量降低,过细则动力消耗大。过去,在国外

First, the foreword Pelletizing pellet production is an important process, the quality of the pellet is good or bad, a direct impact on pellet production and quality. The particle size and particle size of raw materials, played a decisive role on the quality of green balls. Therefore, foreign countries attach great importance to the preparation of raw materials, especially the grinding of raw materials fineness. Foreign pellet plant usually before the construction, according to the nature of raw materials, after grinding and pelletizing and other experimental studies to determine the best grinding fineness. Because the particle size is too coarse pellets to reduce the quality, too small then the power consumption. In the past, abroad
