PURPOSE:To permit uniform delivery of powdered granule and reduce the dispersion of the staying time during application in a shaft kiln etc, by permitting a fixed amount of powdered granule to be delivered freely and airtightly by the synchronous driving of the bottom plate and the shutter of a delivery chamber. CONSTITUTION:When a shutter 5 reaches the limit position of left-ward revolution and the feeding port part 13 comes close to the outside of the opened part 4A, an bottom plate 7 is opened, and the powdered granule in a partitioning chamber 4, e, g., pellets 2 are discharged from the opened part 4C. When the bottom plate 7 is closed and the shutter 5 begins rightward revolution, the feeding port part 13 shifts so as to scan the opened part 4A, and the pellets 2 are dropped-off and partitioned by an introducing plate 15 and stored on the closed bottom plate 7 and on the bottom part 4D. When the shutter 5 turns further and reaches the limit position, the shutter 5 is reversed, and similar partitioning is performed, and when the shutter approaches the limit position, inflow of air into a shaft furnace A is obstructed, and the bottom plate 7 is opened to discharge the pellets 2 onto a conveyor 10. |
