Feedwell is the heart of a thickener - Conference Papers

Abstract: Thickeners that produce non-Newtonian underflow suspensions use the same feedwells as with other thickener types. The functions of converting the horizontal momentum of the feed to a vertical flow and the promoting flocculation of the suspended solids are the same for any thickener.

How a Thickener Works - Mineral Processing & Metallurgy

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...

Flocculant Dilution System in Thickener Feed well

In order to maximise the benefits obtained from flocculating agents when used as settling aids in high rate and conventional thickeners, it is often necessary to dilute the thickener feed prior to flocculant addition. In some cases, no flocculation at all is possible unless dilution water is used. The most common method of diluting thickener feed has been to recirculate some of the thickener ...
