Abstract

APARATO PARA LA PREPARACION DE CONGLOMERADOS POROSOS DE BAJA DENSIDAD. LAS MATERIAS PRIMAS PASAN, A TRAVES DE DISPOSITIVOS DE PESADO Y REPARTO INDIVIDUALES, A UN MEZCLADOR QUE TIENE LA ENTRADA REGULABLE DE AGUA. LA MEZCLA ACUOSA (26) PASA POR UN REPARTIDOR (20) QUE LA DEPOSITA SOBRE UNA CINTA MOVIL (22), REGULANDOSE EL ESPESOR DE LA CAPA CON UN RANURADOR Y CORTADOR ROTATIVO, PASANDO A CONTINUACION POR UN HORNO PARA SU SECADO. SE UTILIZA EN LA PRODU<CCION DE SILICIO Y FERROSILICIO.
