我国烧结生产工艺流程,目前分为热矿工艺和冷却工艺两大类型。生产热矿的因烧结矿没有冷却,并且多数厂又没有采用机械筛分设备筛除热返矿,致使在成品烧结矿中含有大量(20—30%)的小于5毫米的粉末。另一方面,采用固定筛筛分时,在返矿中也含有大量(30—40%)的可做为成品的大于5毫米的烧结矿。这种 China’s sintering production process, currently divided into two major types of hot ore and cooling technology. The hot ore produced by the sinter is not cooled, and most plants are not using mechanical screening equipment to screen the hot returned ore, resulting in the finished sinter contains large (20-30%) of less than 5 mm powder. On the other hand, when using a fixed sieve, there is also a large amount (30-40%) of sinter ore larger than 5 mm which can be used as a finished product in the ore return. This
