Abstract

abstract disclosed is a process for calcining active blending material involving feeding material outside of a kiln head and the blending material obtained. the process comprises feeding material from outside of kiln head of rotary kiln into inside of kiln hood and to grate cooler, wherein the material is coal gangue, shale, clay, peat, mud and the like which can form active cement component through low temperature calcining, and calcining the material at low temperature. disclosed also is a cement production apparatus for carrying out the process provided, comprising feeder nose(s) provided on the kiln hood and/or grate cooler for feeding the material. wo2013/078839 tradução do resumo resumo patente de invenção: "processo para calcinar um material de mistura com alta atividade por alimentação fora do cabeçote de forno e seu aparelho". a invenção refere-se a um processo para calcinar um material de mistura ativo que envolve alimentar o material fora de um cabeçote de forno e o material de mistura obtido. o processo compreende alimentar o material de fora do cabeçote de forno do forno rotativo para dentro da coifa de forno e para o resfriador de grade, em que o material é ganga de carvão, xisto, argila, turfa, lama e similares o qual pode formar um componente de cimento ativo através de calcinação de baixa temperatura, e calcinar o material em baixa temperatura. descrito também está um aparelho de produção de cimento para executar o processo provido, que compreende nariz(es) de alimentador provido(s) sobre a coifa de forno e/ou resfriador de grade para alimentar o material.
