To provide a cement production apparatus in which heat-exchanging efficiency can be improved by even pre-heating by supplying material equally to cyclones above a duct and which can perform an operation with low pressure loss and small energy consumption.A cement production apparatus includes: a duct 21 provided between upper cyclones 13A and a lower cyclone 13B being provided below the upper cyclones 13A, the duct 21 in which the exhaust gas drained from the lower cyclone 13B flows upward, distributing and introducing the exhaust gas to the upper cyclones 13A; a plurality of material-supplying pipes 22 for supplying cement raw material provided on the duct 21 below a distribution part 23 to the plurality of the upper cyclones 13A with a same number of distribution outlets 21a among the upper cyclones 13A; and connection ports 22a of the material-supplying pipes 22 to the duct 21 each provided at each of positions corresponding to swirl flows of the exhaust gas poured into the distribution outlets 21a.
