Abstract

LA CALCINACION DE LA DIATOMITA SE EFECTUA EN EL SENO DE UN CHORRO DE GAS EN ESPIRAL A ALTA TEMPERATURA, EN EL QUE PERMANECE EN SUSTENTACION UN ANILLO DE BOLAS REFRACTORIAS, ANILLO EN EL SENO DEL CUAL SE LLEVA A CABO LA CALCINACION Y LA AGLOMERACION CONTROLADA DE LAS PARTICULAS DIATOMITICAS . LA ESTRUCTURA AMORFA DE LA SILICE SE CONSERVA: SE OBTIENEN ASI AGENTES DE FILTRACION MUY PERMEABLES PRACTICAMENTE EXENTOS DE CRISTOBALITA.
