烧结用石灰石除了必须具备适宜的化学成分外,还必须保证粒度合格,加工能耗低。一般说来,石灰石既可在矿山加工,也可在冶金厂内加工。在冶金厂内加工时,又可分为在料场中加工和在烧结厂中加工。在中国,石灰石都在烧结厂中加工。入厂石灰石的粒度大都为80～0毫米或40～0毫米,然 In addition to sintering with limestone must have the appropriate chemical composition, but also must ensure that the particle size is qualified, low processing energy consumption. In general, limestone can be processed both in mines and in metallurgical plants. When processing in the metallurgical plant, it can be divided into processing in the stockyard and processing in the sintering plant. In China, limestone is processed in the sintering plant. Enter the limestone particle size is mostly 80 ~ 0 mm or 40 ~ 0 mm, of course
