The effects of the slurry flow rate, feed solids concentration, particle settling velocity and drum rotational speed on the hold-up solids concentration were investigated.At low drum speeds, the hold-up solids concentration was much higher than that of the feed. However, at higher drum speeds, the hold-up solids concentration approached that in the feed. At a given drum speed, the hold-up solids concentration was found to vary linearly with the feed solids concentration. A semi-empirical correlation was developed to predict the hold-up solids concentration using the drum Froude number, the single particle drag coefficient and a dimensionless slurry feed rate.On a mené une étude expérimentale afin d\u0026amp;amp;amp;amp;#39;examiner l\u0026amp;amp;amp;amp;#39;écoulement de boues en légère décantation dans un tambour rotatif horizontal. Les effets du débit de la boue, de la concentration des solides d\u0026amp;amp;amp;amp;#39;alimentation, de la vitesse de décantation des particules et de la vitesse rotationnelle du tambour sur la concentration des solides en rétention, ont été étudiés.À de faibles vitesses de tambour, la concentration des solides en rétention est beaucoup plus élevée que dans le cas des solides d\u0026amp;amp;amp;amp;#39;alimentation. En revanche, à des vitesses de tambour élevées, la concentration des solides en rétention se rapproche de celle obtenue dans l\u0026amp;amp;amp;amp;#39;alimentation. À une vitesse de tambour donnée, on a trouvé que la concentration des solides en rétention variait linéairement avec la concentration des solides d\u0026amp;amp;amp;amp;#39;alimentation. On a mis au point une corrélation semi-empirique afin de prédire la concentration des solides en rétention au moyen du nombre de Froude du tambour, du coefficient de traînée des particules individuelles et une vitesse d\u0026amp;amp;amp;amp;#39;alimentation des boues adimensionnelle.","author":[{"@context":"https://schema.org","@type":"Person","name":"Jacob

conducted to examine the flow of slightly settling slurries in a horizontal rotary drum. The effects of the slurry flow rate, feed solids concentration, particle settling velocity and drum rotational speed on the hold-up solids concentration were investigated.At low drum speeds, the hold-up solids concentration was much higher than that of the feed. However, at higher drum speeds, the hold-up solids concentration approached that in the feed. At a given drum speed, the hold-up solids concentration was found to vary linearly with the feed solids concentration.
