Abstract

The invention relates to a feed mechanism suitable for use in introducing a feed flow into a process vessel. More particularly, but not exclusively, the invention relates to a feed mechanism suitable for use as a feed well for a thickener. The feed mechanism includes a feed well chamber for receiving the feed, the feed well chamber being of cylindrical configuration and having an operatively top end and operatively bottom end; and a flow guiding arrangement comprising a plurality of blades located at least partially below the bottom end of the feed well chamber.
