Abstract:
1. A charging device for charging a shaft furnace, comprising a rotary distributor comprising a plurality of sliding channels joined by a junction slide from which each of said plurality of sliding channels extends; a variable drive for rotating said plurality of sliding channels about an essentially vertical axis of rotation with an adjustable velocity, wherein said junction slide is arranged and shaped such that said sliding channels are individually selectable for a flow of charge material based on at least one of the adjustable velocity and rotational direction of said rotary distributor, as actuated by said variable drive, wherein the length and/or inclination of at least two of said plurality of sliding channels are arranged to lead charge material to a different annular area of a charging surface, wherein outputs of a totality of said plurality of sliding channels extending from said rotary distributor are positioned to extend into an area covering at most 180° of an angular sector taken about an essentially vertical axis of rotation of said plurality of sliding channels, and wherein said plurality of sliding channels includes three or more sliding channels.
