PURPOSE: A rotary kiln with improved heat using and raw material saving functions is provided to improve heat use efficiency because hot air in the rotary kiln is not exposed to the outside when a raw material is supplied to the rotary kiln. CONSTITUTION: A rotary kiln with improved heat using and raw material saving functions comprises a rotary path(100) and a raw material supply unit. The rotary path has an exhaust unit and a burner. The burner heats raw materials supplied from the raw material supply unit. The raw material supply unit is installed in the rotary path to be located at the rear of the exhaust unit and comprises an inlet pipe(200) and a snail-shaped pipe(300). The inlet pipe is installed on the outer surface of the rotary path and has a spade(230). The snail-shaped pipe surrounds the inlet pipe so that the rotary path can be rotated and supplies raw materials to the rotary path. |
