Abstract
An edge plate of prescribed height is provided around three sides except a free end side of a swinging plate that can close the lower end of an ore fines inlet pipe which is tilted at a prescribed angle. By the edge plate of prescribed height, when the swinging plate is opened, the ore fines are allowed to flow out only from the free end side of the swinging plate provided that the opening height is held within the height of the edge plate , and an accurate flow control of ore fines can thus be achieved.
