Abstract

MÉTODO PARA PRÉ-TRATAMENTO DE MATERIAL DE SINTERIZAÇçO. A presente invenção refere-se a um método para pré-tratamento de um material de sinterização usando como material pelo menos dois tipos de minério de ferro contendo grãos brutos e pó fino, usando-se um primeiro peletizador para fazer o pó fino aglutinar-se aos grãos brutos formando grãos de núcleo de modo a produzir pelotas do tipo S, e usando-se um segundo peletizador para peletizar apenas pó fino ou principalmente pó fino para produzir pelotas do tipo P, cujo método de produção de pelotas do tipo S pelo ajuste da quantidade de pó fino fornecido ao mencionado primeiro peletizador de forma que a espessura média do aglomerado de pó fino para os grãos de núcleo se tornem 50 a 300 p~m e fornecendo-se o pó fino remanescente não fornecido ao mencionado primeiro peletizador para o segundo peletizador.
