| 摘要 |
The invention relates to a method and apparatus for thickening liquids carrying suspended particles, such as slurry containing minerals, by using a thickening apparatus (1) comprising a tank (2) whereby pulp of higher relative density tends to settle towards the bottom of the tank, forming a bed of thickened pulp (3), and dilute liquid (9) of lower relative density is thereby displaced towards the top of the tank, a feedwell (4), which includes a chamber having means for receiving fed material (5), such as slurry and at least one outlet in fluid communication with the tank and means for distributing the material in the tank, at least one feedpipe (8) for feeding the material (5), at least slurry, into the feedwell, when the feedpipe cross-sectional area for the fed material (5) is constantly varying when the flowrate inside the feedpipe (8) varies. |
