Rotary kiln for cement production and using method thereof

The invention relates to the technical field of rotary kilns, in particular to a rotary kiln for cement production and a using method of the rotary kiln. According to the rotary kiln for cement production and the use method of the rotary kiln, lubricating oil in a column pipe is pressed out along a trace gap between a movable ball and a ball opening to achieve atomized oil spraying, the lubricating oil is sprayed to a wheel belt to guarantee the lubricating effect between the wheel belt and a riding wheel and between the wheel belt and a ring groove, and therefore atomized spraying of the lubricating oil is achieved through rotation of the wheel belt; the surface of the wheel belt can always keep fresh and proper amount of lubricating oil, meanwhile, the injection function is achieved, clean operation of a friction pair is facilitated, the possibility that pollution impurities and abrasion particles return to an oil cavity can be eliminated, the oil cavity does not have an opening to pollute a lubricating med
