Stability control process for C3A content of road clinker discharged from kiln

The invention discloses a stability control process for the C3A content of road clinker discharged from a kiln. The stability control process comprises the following steps: reducing mixing during material leveling; cleaning and drying the road clinker to reduce the mud content; additionally arranging an air pipe on a poking site to ensure material discharging smoothness and improve calcination quality; regulating the proportion of the road clinker, wherein the regulated road clinker comprises the following components in parts by weight: 3.2 parts of C3A, 50.22 parts of CaO, 1.28 parts of MgO, 12.8 parts of SiO2, 2.5 parts of Al2O3 and 3.7 parts of Fe2O3. According to the stability control process for the C3A content of the road clinker discharged from the kiln, the defects of high mud content, instable quality, unreasonable proportion and the like in the prior art can be overcome, and the advantages of low mud content, stable quality and reasonable proportion can be achieved.
