Title (EN) METHOD AND APPARATUSES FOR SCREENING
(FR) PROCÉDÉ ET APPAREILS DE TAMISAGE
Abstract:
(EN) Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame (1510) having a plurality of openings (1513) arranged in a lattice and a plurality of screening cartridge assemblies (1610a,1610b, 1610c) affixed to the grid frame (1510) to cover the respective openings (1513) of the grid frame (1510). The screening cartridge assembly (1610a, 1610b, 1610c) includes a case (1630a) and a screen assembly (1640a, 1640b) fitted into the case (1630a), and may be affixed to a set of transversal member (1512) of the grid frame (1510). The case (1630a) may be an injection molded thermoplastic polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across an exterior portion of the grid frame (1510).
(FR) La présente invention concerne des procédés et des appareils de tamisage. Selon des modes de réalisation, la présente invention concerne un appareil de type corbeille tamisante pour tamiser un matériau, comprenant un cadre grillagé (1510) ayant une pluralité d'ouvertures (1513) agencées dans un treillis et une pluralité d'ensembles cartouches de tamisage (1610a,1610b, 1610c) fixés au cadre grillagé (1510) pour recouvrir les ouvertures (1513) respectives du cadre grillagé (1510). L'ensemble cartouche de tamisage (1610a, 1610b, 1610c) comprend un boîtier (1630a) et un ensemble tamis (1640a, 1640b) ajusté dans le boîtier (1630a), et peut être fixé à un ensemble d'éléments transversaux (1512) du cadre grillagé (1510). Le boîtier (1630a) peut être en polyuréthane thermoplastique moulé par injection ou en polymère thermodurci. Les éléments de tamisage forment ensemble une surface de tamisage généralement continue dans une partie extérieure du cadre grillagé (1510).
