SILO SYSTEM

The present invention provides a silo system including a plurality of silo bins storing coking coal; and a conveyor belt provided in the silo bins to transfer the coking coal to the silo bins in order to prevent generation of a muddy coal due to mixture of the coking coal with moisture within the silo bins. The silo system comprises: at least one first silo bin arranged on a lower side of the conveyor and inputting the coking coal inside by a scraper which transfers the coking coal to a side of the conveyor belt; a second silo bin arranged on a lower side of an end of the conveyor belt and inputting the coking coal which falls inside; a mobile guiding chute disposed on the end of the conveyor belt to move forward and backward, and adhered to the end of the conveyor belt when the coking coal is inputted into the first silo bin to prevent the remaining matter, including a falling water, from being inputted into the second silo bin; and a controller controlling the guidance chute to be adhered to the end of the conveyor belt such that the remaining matter, falling toward the second silo bin, is prevented from being inputted into the second silo bin when the coking coal and controlling the guidance chute to be separated from the end of the conveyor when the coking coal is inputted into the second silo bin.
