Title (EN) IMPROVED SHALE SHAKER
(FR) TAMIS VIBRANT AMELIORE
Abstract: front page image
(EN)A shale shaker comprising two separate filter screens, one above the other, to provide an upper and a lower screen, and drive means adapted to drive the screens separately in at least lateral vibration. One or both screens are vibratable in more than one mode, for example vertical and/or horizontal and/or orbital mode. The screens may be of similar or different mesh. Typically the upper screen is of a coarser mesh that of the lower screen.
(FR)L'invention concerne un tamis vibrant comprenant deux éléments de tamisage séparés et superposés, avec des moyens permettant d'actionner séparément l'élément de tamisage supérieur et l'élément de tamisage inférieur, pour leur imprimer un mouvement vibratoire latéral. L'un des deux éléments de tamisage ou les deux peuvent vibrer dans plus d'un mode, par exemple vertical et/ou horizontal et/ou orbital. Les éléments de tamisage peuvent être similaires ou différents. Typiquement, l'élément de tamisage supérieur a des ouvertures plus grandes que celles de l'élément de tamisage inférieur.
