A charging installation (10) of a shaft furnace comprises a first storage hopper (12) and a second storage hopper (12'), arranged in parallel with respect to each other; each of the first and second storage hoppers (12, 12') having an inlet (14, 14') for receiving material and an outlet (16, 16') for feeding material into the shaft furnace. A receiving hopper (18) is arranged upstream of the first and second storage hoppers (12, 12'), the receiving hopper (18) being pivotably arranged about a horizontal pivoting axis (22) and configured for receiving material therein and for distributing the material to one of the first and second storage hoppers (12, 12'). The receiving hopper (18) comprises an inlet (24) for receiving material from a feed apparatus (20) and an outlet (26) for feeding the material to the first and second storage hoppers (12, 12'), the receiving hopper (18) being pivotable at least between two transfer positions, wherein, in a first transfer position the outlet (26) of the receiving hopper (18) is in alignment with the inlet (14) of the first storage hopper (12) and, in a second transfer position, the outlet (26) of the receiving hopper (18) is in alignment with the inlet (14') of the second storage hopper (12'). A rest position is arranged between said first and second transfer positions. According to an aspect of the present invention, the charging installation (10) further comprises a material gate (30) associated with the outlet (26) of the receiving hopper (18); and an actuating mechanism associated with the material gate (30) for opening and closing the outlet of the receiving hopper (18), the actuating mechanism is configured so as to essentially close the outlet (26)of the receiving hopper (18)when the receiving hopper (18) is in the rest position and so as to essentially open the outlet (26) of the receiving hopper (18)when the receiving hopper(18)is in either of the first and second transfer positions. The actuating mechanism (32) is configured so as to actuate the material gate (30) through the pivoting movement of the receiving hopper (18). |
