Abstract

PROCEDIMIENTO Y APARATO PARA CALCINAR YESO. EL PROCESO CONSISTE EN CALENTAR DIRECTAMENTE UN LECHO DE YESO PULVERIZADO MEDIANTE LA INTRODUCCION DE GAS CALIENTE EN DICHO LECHO Y EN MANTENERLO A UNA TEMPERATURA APROPIADA PARA OBTENER EL SEMIHIDRATO DE SULFATO CALCICO. AL OBJETO DE EVITAR LA FORMACION DE ANHIDRITA INSOLUBLE, SE PULVERIZA AGUA U OTRO LIQUIDO ACUOSO EN LA FASE GASEOSA. EL APARATO CONSTA DE UN RECIPIENTE (11) DONDE SE REALIZA LA CALCINACION, EL CUAL ESTA RODEADO POR UNA CAMARA DE CALDEO (12); DE UN QUEMADOR (14) U OTRA FUENTE DE GAS CALIENTE PARA CALENTAR EL CONTENIDO DEL RECIPIENTE (11) POR CONDUCCION A TRAVES DE LAS PAREDES Y PARTICULARMENTE A TRAVES DE SU FONDO; DE UN AGITADOR MECANICO (19) IMPULSADO POR UN ARBOL (20) DE ACCIONAMIENTO; Y DE UN PULVERIZADOR DE AGUA O DE OTRO LIQUIDO ACUOSO.
