PURPOSE:To make the service life of two units of stationary hopper approximately equal and to assure the service life as a whole by alternately charging the ore and relatively soft coke to be carried in by two units of skip cars dividedly to the two stationary hopper according to a prescribed repetitive pattern. CONSTITUTION:The raw materials are charged from the skip cars 2-I, 2-II via a moving receiving chute 5 to two units of the right and left stationary hopper 6a, 6b by the method shown in the table. More specifically, the throwing of the coke and ore is executed in the sequence shown in A, B and the next throwing of the coke is executed by changing the place to be thrown with the coke from the hopper 6a to 6b and further changing the throwing sequence of the cars 2-I, 2-II as shown in figure E. The 1st throwing from the car 2-II to the hopper 6b is, therefore, executed in the route just slightly passing the chute 5 as shown in figure E. The 2nd throwing from the car 2-II to the hopper 6b is executed through the route long along the chute 5. On the other hand, the 1st throwing is executed in the long route and the 2nd throwing in the short route so as to correspond to the example of figure B as shown in figure F in the example of figure E for throwing the ore.
