Abstract

EL TAMAÑO MEDIO DE LOS CRISTALES DE SULFATO AMONICO SE AUMENTA HACIENDO PASAR CRISTALES DE SULFATO AMONICO CON UN TAMAÑO INFERIOR A TRAVES DE UN APARATO DE MULTIPLES ETAPAS EN EL QUE LOS CRISTALES SE PONEN EN CONTACTO CON UN SULFATO AMONICO ACUOSO PULVERIZADO EN UNA PRIMERA CAMARA CALENTADA PARA AUMENTAR EL TAMAÑO MEDIO DE LOS CRISTALES, LOS CRISTALES AUMENTADOS PASAN DESPUES A TRAVES DE UNA SEGUNDA CAMARA CALENTADA PARA SECAR LOS CRISTALES AUMENTADOS.
