Abstract (en)

[origin: EP3372936A1] The present disclosure provides a raw material charging apparatus including a first hopper disposed above a storage vehicle traveling along a path; a first charging chute disposed below the first hopper and extending obliquely, wherein the first charging chute has a through-hole defined therethrough in a direction intersecting the extending direction of the first chute; a second hopper disposed above the storage vehicle and spaced apart from the first hopper; and a second charging chute disposed below the second hopper and the first charging chute and extending obliquely. Further, the present disclosure provides a raw material charging method using the apparatus. In this way, the apparatus and method may improve the collection rate and strength of the sintered ore in the upper portion of the raw material layer.
