Abstract

Provided is a cement production device that increases heat exchange efficiency by causing the pre heating of starting materials supplied to cyclones above a guide tube to be uniform and can cause an operation having low pressure loss and low energy consumption. In the cement production device a guide tube (21) is provided that causes exhaust gas led out from a lower level cyclone to flow upwards to be distributed and to be led to upper level cyclones. Starting material supply tubes (22) that supply cement starting materials are respectively connected to both sides of one lateral surface of the guide tube (21) at a position below the distribution section (23) of the guide tube (21) to the upper level cyclones. A supply amount controller (26) that adjusts the amount of supply of cement starting materials to the starting material supply tubes (22) is provided to a position upstream of the starting material supply tubes (22). The ratio H/D of the vertical distance (H) from a horizontal plane (P1) passing through the center of the distribution exits (21a) of the upper level cyclones to a horizontal plane (P2) passing through the center of the connection openings (22a) of the starting material supply tubes (22) with respect to the diameter (D) of the guide tube (21) is set to 1.4-2.5.
