烧结矿入炉前进行筛分,去掉大部分小于5mm的粉矿,是高炉节焦增铁的一项有效措施。采用机械筛筛分,似乎已成定论。无论是筛分烧结矿,还是筛分其他物料,机械筛普遍存在着噪音大、寿命短、维修量大等缺点。筛分效率也不算高,据使用机械筛的几个主要铁厂的资料,一般机械筛筛分效率只有30～40％,尽管在筛子结构上,筛孔形状,筛子材质 Sintering into the furnace before screening, remove most of less than 5 mm of fines, blast furnace section is an effective measure to increase iron. The use of mechanical screening, seems to have become a conclusion. Whether it is sieving sinter, or screening other materials, mechanical screening ubiquitous noise, short life, large maintenance and other shortcomings. Screening efficiency is not high, according to the use of mechanical screening of several major ironworks, general mechanical screening efficiency of only 30 to 40%, although the sieve structure, sieve shape, sieve material
