土法烧结中混料的均匀与否,直接关系到 FeO 的高低和返矿的多少。特别是当消石灰配比较高的时候,往往由于混料不均,造成成品率降低,返矿增多。我厂在混料方法改进前 FeO 含量一般都在17%～20%左右,成品 Soil sintering in the mixture of uniform or not, is directly related to the level of FeO and the amount of return. Especially when the high proportion of hydrated lime, often due to uneven mixing, resulting in lower yield, increased return to mine. I plant in the mixing method to improve the content of FeO are generally 17% to 20%, the finished product
