Abstract
An arrangement for feeding fine-grained matter to a concentrate or matte burner (1) of a suspension smelting furnace (2). The arrangement comprising a fluidization arrangement (3) for feeding fluidized fine-grained matter into a dosing bin (4), and a conveyor means (6) for feeding fluidized fine-grained matter from the dosing bin (4) to the concentrate or matte burner (1) of the suspension smelting furnace (2), and a loss-in-weight controller (5) between the dosing bin (4) and the conveyor means (6). The arrangement comprises an impact cone (8) arranged below a filling valve (7) between the fluidization arrangement (3) and the dosing bin (4) for distributing fluidized fine-grained matter flowing from the fluidization arrangement (3) within the dosing bin (4).
