Abstract
LE PROCEDE DE FABRICATION D'UN ENGRAIS AU SILICATE DE POTASSIUM SOLUBLE DANS L'ACIDE CITRIQUE COMPREND LE MALAXAGE D'UN MELANGE CONSTITUE ESSENTIELLEMENT DE CARBONATE DE POTASSIUM, DE CENDRE VOLANTE, DE CHARBON PULVERISE, ET D'AUTRES MATERIAUX DE DEPART INDISPENSABLES ET D'UNE SOLUTION DE POTASSE CUASTIQUE COMME LIANT, PUIS LA MISE EN GRANULES DU MELANGE MALAXE, LE SECHAGE DU PRODUIT EN GRANULES A UN ETAT SEC PRESQUE ABSOLU, ET UNE CALCINATION DU PRODUIT EN GRANULES SECHES, A LA SUITE DE QUOI, UNE REACTION CHIMIQUE SE PRODUIT ENTRE LE POTASSIUM ET LE SILICIUM PRESENT DANS LA CENDRE VOLANTE QUI A POUR EFFET DE LES CONVERTIR EN SILICATE DE POTASSIUM SOLUBLE DANS L'ACIDE CITRIQUE. UN DISPOSITIF POUR LA PRATIQUE DU PROCEDE COMPREND UNE PLURALITE DE DISPOSITIFS D'ALIMENTATION EN CONTINU, UN MALAXEUR CONTINU, UNE EXTRUDEUSE POUR LA FORMATION EN GRANULES, UN SECHOIR A LIT FLUIDISE, UN FOUR DE CALCINATION A LIT FLUIDISE ET UN DISPOSITIF DE REFROIDISSEMENT DU PRODUIT CALCINE.
