Uniformly supply the raw material to each of the cyclone and the upper conduit, with increasing the heat exchange efficiency to average out the warm-up, low pressure drop, the energy consumption provides a cement-producing device that can be performed with less operation. Cement manufacturing apparatus, a plurality of the upper cyclone (13A) and between the bottom side cyclone (13B) disposed on the lower side, partitioned by flowing the exhaust gas is derived from the lower end side cyclone (13B) upwardly the top of each side cyclone and a conduit (21) installed to drive the (13A), the conduit a plurality of raw material feed pipe 22 for feeding the lower position, the cement raw materials than the distributor (23) to the top side of the cyclone (13A) in the 21 this and the top side cyclone is (13A) installed to the same number of to the dispensing outlet (21a), each connecting port (22a) to the conduit (21) of the raw material supply pipe 22, the exhaust gas flowing into the respective dispensing outlet (21a) It is disposed one by one at a position corresponding to the individual flow of the swirling flow.
