Zusammenfassung:The utility model relates to the technical field of mixture separation, in particular to a cement kiln with a back-mixing cone device, which comprises a preheater group, a decomposing furnace and a cracking furnace, a rotary kiln is respectively communicated with the decomposing furnace and the cracking furnace, the preheater group is communicated with the decomposing furnace, the preheater group consists of a plurality of connected preheaters, and the preheaters are communicated with the cracking furnace. A back-mixing cone device is arranged in the preheater and comprises a back-mixing cone tower cap and a supporting rod, the back-mixing cone tower cap is arranged in the preheater, the windward side of the back-mixing cone tower cap faces fluid in the preheater, and one end of the supporting rod is connected with the periphery of the back-mixing cone tower cap. The back-mixing cone device is arranged in the preheater, so that airflow in the preheater tends to be stable easily, and the gas turbulence time is
