The difficulty of mixing coke powder with retorting coal is solved through such measures as strengthening particle size control of fuel and optimizing the processibility aiming at the retorting coal is with such disadvantages as poor controllability of particle size after cracking, more moisture and non uniform combustion velocity. The maximum proportion of retorting coal is 53% of fuel consumption so that the whole sintering production is smooth, the output increases and quality of sinter is stable. Moreover, the utilization coefficient of sintering machine increases by 0.021 t/m2·h, solid fuel consumption decreases by 5.87 kg/t, content of FeO of sinter decreases by 0.18 percentage points, drum index increases by 2.11 percentage points and the RI increases by 1.77 percentage points.
