Provided is cement burning apparatus 1 comprising a dryerfor drying high-water-content organic waste of which water content is 40 mass percent or more, in which combustion gas extracted from outlet portions or ceiling, portions of preheater cyclonesA toD of a cement kilnis fed to the dryer. As the dryer, a grinding-type flash dryer, which directly contacts the combustion gas G with the high-water-content organic waste W while grinding it, can be used. In addition, the apparatusfurther comprises a coarse powder separatorfor separating coarse powder from the combustion gas extracted from the range described above, and the combustion gas G from which dust is separated by the coarse powder separatorcan be fed to the dryer, and the dust concentration of the gas fed to the dryermay be adjusted to 0.05kg/Nmor more and 0.35kg/Nmor less.
