Abstract
A cement production apparatus having: a ductin which exhaust gas drained from a lower cyclone flows upward, distributes and introduces the exhaust gas to upper cyclones; material-supplying pipesfor supplying cement raw material connected to both side parts of one side surface of the ductbelow a distribution partamong the upper cyclones; and a supply-amount controllerprovided on an upstream position above the material-supplying pipesfor controlling supply-amounts of the cement raw material to the material-supplying pipes: and when H is a vertical distance between a horizontal surface Ppassing through centers of distribution outletsof the upper cyclones and a horizontal surface Ppassing through centers of connecting portsof the material-supplying pipes, and D is a diameter of the duct, a ratio H/D is set to 1.4 to 2.5.
