Abstract
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 ductprovided between upper cyclonesA and a lower cycloneB being provided below the upper cyclonesA, the ductin which the exhaust gas drained from the lower cycloneB flows upward, distributing and introducing the exhaust gas to the upper cyclonesA; a plurality of material-supplying pipesfor supplying cement raw material provided on the ductbelow a distribution partto the plurality of the upper cyclonesA with a same number of distribution outletsamong the upper cyclonesA; and connection portsof the material-supplying pipesto the ducteach provided at each of positions corresponding to swirl flows of the exhaust gas poured into the distribution outlets
