A feedwell assembly for a thickener/clarifier includes a feedwell body (22; 50; 112; 166; 240), at least one infeed conduit (21; 52; 120; 226) connected at a downstream end to the body, and at least one spin or rotation inducement element (30; 54, 54', 54'; 78; 101, 102; 178, 184; 245) disposed as part of the infeed conduit for imparting rotation or spin to a slurry stream (42; 58; 108, 110; 182, 188) fed to the feedwell body via the infeed conduit. The spin or rotation inducement element may be a fixed and rigid structural member such as a vane or baffle, or include actively operated elements (35; 53, 53'). Multiple such spin or rotation inducement elements may be provided in various locations in the infeed conduit. |
