Abstract
Providing a cement production apparatus in which raw material is supplied into a duct with being dispersed uniformly so that heat-exchanging efficiency is improved by even preheating and clogging and the like are prevented, so that stable operation can be carried out. Between cyclones at an upper stage and a cyclone at a lower stage disposed below cyclones at an upper stage, a ductis provided to introduce exhaust gas to the cyclones at the upper stage with distributing after flowing upward from the cyclone at the lower stage; at a lower position than a distribution partof the duct, a material-supplying pipeis connected for supplying cement raw material; at a connected part of the material-supplying pipeto the duct, a material-guiding chuteon which the cement raw material is supplied from the material-supplying pipeand which drops it into the ductis provided with protruding into the duct; and the material-guiding chuteis formed to have a flat upper surface and to be expandable by sliding so that insertion depth of a tip endfrom an inner-wall surfaceof the ductis 0.15 to 0.5 times of an inner diameter of the duct
