Abstract

PROCEDIMIENTO PARA LA CALCINACION DE CEMENTO-POLVO EN PARTICULAR PARA LA FABRICACION DE CEMENTO. EL POLVO EN BRUTO, DESPUES DE UN CALENTAMIENTO PREVIO POR LA APORTACION DE CALOR, ES CALCINADO EN POR LO MENOS DOS FASES ANTES DE SER COCIDO DENTRO DE UN HORNO. DESPUES DE LA FASE DE CALCINACION QUE, VISTA EN LA DIRECCION DE LA CORRIENTE DEL CEMENTO EN BRUTO ES LA PRIMERA Y ANTES DE CUALQUIER FASE QUE LA SIGA A ESTA EN LA DIRECCION DE LA CORRIENTE DEL CEMENTO EN BRUTO, UNA RESPECTIVA PARTE PROPORCIONAL DE GRANULACION FINA DEL CEMENTO EN BRUTO ES SEPARADA DE LA CORRIENTE DEL CEMENTO EN BRUTO Y ES CONDUCIDA HACIA EL HORNO.
