Title (EN) SCREW CONVEYOR TO CONVEY POWDERY MATERIAL, IN PARTICULAR CEMENT OR THE LIKE
(FR) CONVOYEUR À VIS POUR TRANSPORTER UN MATÉRIAU PULVÉRULENT, EN PARTICULIER DU CIMENT OU ANALOGUE
Abstract: front page image
(EN)A screw conveyor (100) to convey powdery material, in particular cement. The screw conveyor (100) comprises: - a transfer screw (70); and - a trough (80) containing the transfer screw (70); the trough (80) being provided with an inlet section (81) and an outlet section (82) of the powdery material. The screw conveyor (100) is characterized in that the screw comprises : - at least a first screw portion (TSEC) having a first law of continuous variation of the pitches of the screw (70), which can be graphically represented by means of a first function having in at least one stretch a first derivative other than zero; and - at least a second screw portion (TSEC) having a second law of continuous variation of the pitches of the screw (70), which can be graphically represented by a second function having in at least one stretch a first derivative other than zero. The first law of continuous variation of the pitches (PTC) is different from the second law of continuous variation of the pitches (PTC).
(FR)L'invention concerne un convoyeur à vis (100) pour transporter un matériau pulvérulent, en particulier du ciment. Le convoyeur à vis (100) comporte:-une vis de transfert (70); et une auge (80) contenant la vis de transfert (70); l'auge (80) étant dotée d'une section d'entrée (81) et d'une section de sortie (82) du matériau pulvérulent. Le convoyeur à vis (100) est caractérisé en ce que la vis comporte: au moins une première partie de vis (TSEC) ayant une première loi de variation continue des pas de la vis (70), qui peut être représentée graphiquement au moyen d'une première fonction ayant dans au moins un étirement un premier dérivé autre que zéro; et au moins une seconde partie de vis (TSEC) ayant une seconde loi de variation continue des pas de la vis (70), qui peut être représentée graphiquement par une seconde fonction ayant dans au moins un étirement un premier dérivé autre que zéro. La première loi de variation continue des pas (PTC) est différente de la seconde loi de variation continue des pas (PTC).
