Abstract

METODO Y DISPOSITIVO PARA LA ELIMINACION DEL AGUA SOBRANTE DE UNA MEZCLA DE YESO Y AGUA. EL METODO CONSISTE EN INTRODUCIR LA MEZCLA DE SULFATO DE CALCIO HIDRATABLE Y DE AGUA EN EXCESO, EN UN SECADERO COMPUESTO DE CELULAS SEPARADAS POR TABIQUES, ESTANDO INSTALADOS EN CADA UNA DE DICHAS CELULAS UN QUEMADOR DE GAS. EL PROCESO DE SECADO TERMICO COMIENZA Y TERMINA ANTES DE FINALIZAR LA HIDRATACION DEL SULFATO DE CALCIO, DE TAL MODO QUE SE INTERRUMPE LA OPERACION DE SECADO EN UN MOMENTO ADECUADO PARA QUE EL PRODUCTO CONSERVE EL AGUA SUFICIENTE PARA LA HIDRATACION DEL SULFATO DE CALCIO, CON UN SOBRANTE DE AGUA QUE NO SOBREPASE UN 5%.
