Un método para alimentar materia de grano fino a un quemador de mata o concentrado de un horno de fusión por suspension, en donde el método comprende una primera etapa de alimentación para alimentar materia de grano fino en una disposicion de su fluidizacion, una etapa de fluidizacion para producir materia de grano fino fluidizada con una disposicion de fluidización, una segunda etapa de alimentacion para alimentar materia de grano fino fluidizada.

摘要

The invention relates to a method and to 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).
