In order to improve the output and quality of sinter and optimize the parameters of sinter machine,the double-roll+four-roll crushing process is adopted to replace the original double-roll crushing process. Through a series of measures,the content of coke powder with a size of+5mm decreases from 20.16％ to 9.45％,and the content of coke powder with a size of-3mm increases to 70.64％ from 62.98％. The parameters of the sinter machine are optimized,the end point temperature is reduced by 17.13 ℃ and the main tube temperature is reduced by 9.15 ℃. The sinter output increases by 140 tons/day,the drum strength increases by 1.24％,the average particle size increases by 0.45 mm,the content of-10 mm particle size decreases by 1.02％,and the fuel consumption decreases by 0.72 kg/t.
