PURPOSE:To uniformalize the distribution of particle size in each tank by disposing a shuttle conveyer above a two-port hopper, thereby to bring a raw ore into collision with a hood in a tank on this side in the moving direction, and thereby to lift up the hood so that a raw ore is allowed to take a free drop in a tank advance side. CONSTITUTION:When a head pulley 8 of a shuttle conveyer 7 disposed above a two-port hopper 1 is positioned above a tank 1'', a receive roller 29 disposed on the head pulley portion 8 is positioned at a guide portion 21 of a hood 19 pivoted on support plate 17, so that the hood 19 is inclined, with the free end thereof positioned in the two-port hopper 1. When a raw ore 4 is supplied in such a condition, the raw ore 4 collides with the guide portion 21 of the hood 19, and the raw ore of large particle size rebounds, while the raw ore of small particle size drops in the tank 1'' as it is. On the other hand, when the shuttle conveyer 7 is advanced, the receive roller 29 is positioned at a support portion 22, and the hood 19 is positioned above the conveyer 7. In this arrangement, the raw ore 4 is allowed to take a free drop in the tank 1'. |
