Abstract

LA INVENCION SE REFIERE AL TRATAMIENTO TERMICO DE MATERIALES MINERALES PULVERULENTOS QUE CONSISTEN EN TRATAR LOS MATERIALES EN SUSPENSION EN UN HORNO (10) Y DESPUES EN ENFRIARLOS MEDIANTE UNA CORRIENTE DE AIRE QUE SE UTILIZA DESPUES COMO AIRE DE COMBUSTION EN EL HORNO, SIENDO DESPOLVOREADOS LOS GASES DE ESCAPE DEL HORNO (EN 32) ANTES DE SER LANZADOS A LA ATMOSFERA Y SIENDO RECICLADA LA MAYOR PARTE DEL POLVO POR DEBAJO DEL HORNO. PARA EVITAR QUE LOS MATERIALES TRATADOS CONTENGAN POLVO QUE NO HAYA SIDO SOMETIDO NINGUN TRATAMIENTO, LA OTRA PARTE DEL POLVO SE PONE EN SUSPENSION EN UNA CORRIENTE DE AIRE (70) DERIVADA DE LA CORRIENTE DE AIRE CALIENTE QUE HA SERVIDO PARA ENFRIAR LOS MATERIALES QUE SALEN DEL HORNO (10), Y DESPUES SE SEPARA (EN 68) DE DICHA CORRIENTE DE AIRE DERIVADA Y SE MEZCLA CON LOS MATERIALES TRATADOS ENFRIADOS.
