1. A continuous concentrate feeding equipment, comprising:
a plurality of concentrate supply mechanisms,
wherein each of the plurality of concentrate supply mechanisms includes:
a pressure-adjusting tank that temporarily accumulates granular concentrate;
a lift tank that receives the concentrate from the pressure-adjusting tank and discharges the concentrate to a smelting furnace; and
a pressure control system that controls pressures of the pressure-adjusting tank and the lift tank such that the concentrate is continuously supplied from the lift tank to the smelting furnace throughout a time when the concentrate is received in the pressure-adjusting tank and a time when the concentrate is discharged into the lift tank,
wherein the plurality of concentrate supply mechanisms are connected in parallel to a conveyor for carrying in concentrate from an upstream side of the conveyor to a downstream side thereof, and
wherein supply control means is provided to control supply of the concentrate from the conveyer such that the concentrate reception of the concentrate supply mechanism is performed in order from the upstream side to the downstream side and the concentrate reception of the concentrate supply mechanism at an upstream end is started before the end of the concentrate reception of the concentrate supply mechanism at a downstream end.
