The present invention relates to a rotary kiln. According to an embodiment of the present invention, a rotary kiln comprises: a kiln body forming where a powder is burned, molten, and arranged to be able to rotate; a supply hopper arranged on an inlet of the kiln body, sending the powder inside the kiln body; a supply box receiving the powder to be supplied to the supply hopper; a lifting device lifting the supply box from the ground surface; a powder supplying pipe guiding the powder received from the supplying box to the supplying hopper; and a screw member formed inside the powder supplying pipe to transfer the powder. The present invention is capable of automatically supplying the powder to the hopper so that a user convenience is improved. Moreover, the present invention is capable of preventing the density of the powder from being excessively increased by the powder supplying pipe arranged horizontally on the ground surface, and the screw member arranged inside the powder supplying pipe. Accordingly, the present invention is capable of preventing an increase in the amount of moisture contained in the powder by evenly controlling the density of the powder, thereby solving a problem such as a clogged tube generated in the middle of the transferring process. In addition, the present invention enabling the powder to smoothly be burned and molted by uniformly maintaining an amount of oxygen, thus improving the efficiency of the entire rotary kiln. |
