Abstract

Proceso de fabricación de puzolana con cambio de color y puzolana así obtenida La presente invención se refiere a un proceso de fabricación de puzolana artificial que tiene el color final gris. A fin de realizar los procesos de la manera deseada, la atmósfera del horno deberá contener una baja concentración de oxígeno y la presencia de agentes reductores. Sin embargo, la presencia de monóxido de carbono en el escape del horno no es deseable, debido a los impactos ambientales y al aumento en el consumo de calor específico del horno. Por lo tanto, el proceso descrito en esta invención comprende las siguientes etapas: calentamiento (1), que consiste en calentar las materias primas a una temperatura entre 100 y 350° C hasta el secado del material a una fracción de masa de humedad del 0% hasta el 5% (base húmeda); mezcla (2), que consiste en mezclar las materias primas secas del proceso de calentamiento con la proporción correcta de combustible, del 1% al 5% en fracción de masa, de acuerdo con la concentración de hematita presente en la materia prima; calcinación (3), que consiste en calentar la mezcla de combustible y materias primas a una temperatura entre 700 y 900° C, con una concentración de oxígeno entre el 1% y el 5% y, finalmente, enfriamiento (4), que consiste en una etapa inicial de rápida disminución de la temperatura de la puzolana hasta 600° C y una etapa final de disminución lenta de la temperatura de la puzolana hasta 120° C. Figura 1 Clay = arcilla Or raw material (reddish) = o materia prima (rojizo) Heating / Drying = calentamiento / secado Mixing = Mezcla Solid Fuel = Combustible sólido Calcining = calcinación Hot Reducing Gases – gases reductores calientes Cooling = Enfriamiento Water = agua Air / Reducing Gases = Aire / Gases Reductores Pozzolan (grayish) = Puzolana (grisácea) Figura 2 – inclui o mesmo dizeres. Só há uma inversão nas duas primeiras etapas Figura 3 Carbon = Carbono Clay = arcilla Figura 4 Temperature = Temperatura
