Title (EN) DOUBLE SEPARATOR FOR SORTING PARTICULATE MATERIAL
(FR) SEPARATEUR DOUBLE SERVANT A TRIER DES MATIERES PARTICULAIRES
Abstract:
(EN) A double separator for sorting particulate material, e.g. raw materials of cement or cement clinker comminuted in a roller press, and in which the material charge is suspended in a conveying gas, and consisting of a coarse separator (2), on top of which a fine separator (1) is mounted directly. The coarse separator (2) has a material inlet duct (15), a centrifugal pulverizer or rotor with arms (16) forming a desagglomerator, a gas inlet duct (18) and a material outlet duct (21) for a separated coarse fraction. The fine separator (1) has a material gas inlet duct (9), an additional material inlet duct (11), an outlet duct (3) for a fine fraction in suspension and an outlet duct (10) for a separated coarser fraction.
(FR) Séparateur double servant à trier des matières particulaires, par exemple des matières brutes de ciment ou de clinkers broyées dans une presse à rouleaux, et dans lequel la charge de matériau est suspendue dans un gaz de transport. Le séparateur se compose d'un séparateur grossier (2) au-dessus duquel un séparateur fin (1) est directement monté. Le séparateur grossier (2) comprend un conduit (15) d'entrée de matériau, un pulvérisateur ou rotor centrifuge pourvu de bras (16) constituant un désagglomérateur, un conduit (18) d'entrée de gaz et un conduit (21) de sortie de matériau pour une fraction grossière séparée. Le séparateur (1) de particules fines comprend un conduit (9) d'entrée de gaz, un conduit (11) d'entrée de matériau additionel, et un conduit (3) de sortie pour la fraction fine en suspension, ainsi qu'un conduit (10) de sortie pour une fraction plus grossière séparée.
