摘要： The present disclosure relates to an apparatus of charging a raw material and a method of charging a raw material, and the method includes preparing the raw material; supplying the raw material to a charging chute; and charging the raw material into a storage container by transporting the raw material supplied to the charging chute along a path having a cycloid curve shape, thereby increasing a horizontal separation speed of the raw materials having various densities and sizes separated from the charging chute to improve air permeability of the raw materials.

摘要： The present disclosure relates to equipment for manufacturing sintered ore and a method for manufacturing sintered ore using the same. The equipment for manufacturing the sintered ore includes a plurality of sintering carts that are movable along a movement path and into which a raw material layer is fed, an ignition furnace installed above one side of the movement path to inject a flame to the raw material layer within each of the sintering carts, an ore discharge part installed on the other side of the movement path to discharge the sintered ore in which sintering is completed, a wind box disposed between the ignition furnace and the ore discharge part on the movement path, and a heat quantity controller disposed between the ignition furnace and the ore discharge part over the movement path to supply heat and humidified air to the raw material layer.

摘要： Provided is a sintering apparatus. The sintering apparatus includes a plurality of sintering trailers movably disposed along a moving path and in which a raw material is inserted therein, an ignition furnace disposed above the sintering trailers to spray flames to a top surface of the raw material, a wind box provided in plurality under the sintering trailers along the moving path to suction air downward from the sintering trailers to sinter the raw material, a cooler disposed on one side of the moving path to supply a cooling gas to a sintered ore discharged from each of the sintering trailers, and a first circulation part connected to the cooler to supply at least one portion of the cooling gas supplied to the raw material to an upper portion of the sintering trailer to control a combustion process of the raw material or improve combustion efficiency, thereby improving quality and productivity of the raw material.
