Title (EN) A ROTARY SCREEN DEVICE
(FR) DISPOSITIF ROTATIF DE FILTRAGE
Abstract:
(EN) In a rotary screening device the screen or sieve (12) is stretched across the upper end of the drum (1A) which is rotated about the vertical axis, and the walls of the drum (1A) are frusto-conical or of parabolic section, diverging outwardly to its lower end in order to avoid 'caking' of the sieved particles on the inside of the walls. The walls may be polished or coated with PTFE.
(FR) Dispositif rotatif de filtrage dans lequel le filtre ou le tamis (12) est tendu en travers de l'extrémité supérieure du tambour (1A) tournant autour de l'axe vertical, et les parois du tambour (1A) sont tronconiques ou de section parabolique de sorte qu'elles soient divergentes en direction de l'extérieur au niveau de l'extrémité inférieure, et que la formation d'une croûte de particules, tamisées sur les surfaces internes de parois soit impossible. Les parois peuvent être polies ou enduites de polytétrafluoréthylène.
