Title (EN) SYSTEM FOR SUPPLYING GREEN PELLETS TO FURNACES OF THE MOVING GRATE TYPE USING GRANULOMETRIC SEPARATION
(FR) SYSTÈME D'ALIMENTATION EN BOULETTES CRUES DANS DES FOURS DE TYPE À GRILLE MOBILE PAR SÉGRÉGATION GRANULOMÉTRIQUE
(PT) SISTEMA DE ALIMENTAÇÃO DAS PELOTAS CRUAS EM FORNOS TIPO GRELHA MÓVEL UTILIZANDO SEGREGAÇÃO GRANULOMÉTRICA
Abstract: front page image
(EN)The present invention relates to a method for supplying green iron ore pellets to hardening furnaces, in particular of the moving grate type, the grate carriages being filled with material separated into two different granulometric ranges. The bed of pellets being hardened is therefore composed of equal proportions of green pellets within a finer granulometric range in the lower layer and within a coarser granulometric range in the upper layer.
(FR)La présente invention concerne un procédé d'alimentation en boulettes crues de minerai de fer dans des fours de durcissement, notamment à grille mobile, le remplissage des chariots à grille étant réalisé par ségrégation granulométrique en deux catégories distinctes. Le lit de boulettes à durcir présente donc une répartition uniforme des boulettes crues selon leur granulométrie, avec les plus petites sur la couche inférieure et les plus grandes sur la couche supérieure.
(PT)A presente invenção refere-se ao processo de alimentação de pelotas cruas de minério de ferro em fornos de endurecimento, em especial o de grelha móvel, onde o preenchimento dos carros de grelha é feito com segregação granulométrica em duas faixas distintas. O leito de pelotas a ser endurecida será então composto por proporções iguais de pelotas cruas nas faixas granulométricas de menores na camada inferior e maiores na camada superior.
