| 摘要 |
The invention relates to an apparatus and a method for thickening liquids carrying suspended particles, such as a slurry containing minerals. The thi ckening apparatus comprises a tank (2), a feedwell (4), which includes a cha mber having an inlet for receiving feed slurry (9) and an outlet in fluid co mmunication with the tank and means for distributing the material in the tan k, at least one conduit (5) for feed slurry to deliver a feed slurry (9) int o the feedwell, means for diluting the feed slurry, when at least one separa te dilute liquid conduit (16, 19) is directed tangentially with respect to t he feedwell (4) and at least one inflow aperture (15) is arranged tangential ly with respect to the feedwell for recirculating the dilute liquid from the tank inside the feedwell in order to dilute the feed slurry.
