Multiple unit Knelson installations often employ a central feed distributor to evenly distribute feed amongst multiple Knelson Concentrators.

Knelson manufactured feed distributors operate on a static head principle. They consist of a cylindrical tank with a conical lower section. Feed material is either pumped or gravity-fed into the conical section of the tank and flows upwards towards the individual feed outlets.

Each feed is fitted with an adjustable dart valve to provide precise slurry flow to each Knelson unit on-line. Once feed control has been manually adjusted the on / off control of feed to the units can be accomplished either manually or through fully automated control.

In applications where the solids content of the feed slurry is relatively dilute, the Knelson Feed Distributor can be fitted with an optional overflow launder which will minimize the flow of heavy solids to the overflow subsequently minimizing potential losses in the overflow stream.

The photograph to the right depicts an automated multi-unit Knelson installation employing a Knelson Feed Distributor. While the Knelson units are in operating mode, feed is precisely split amongst the number of units in operation. In the event that several of the units were simultaneously off-line and the volume of feed slurry exceeded the capacity of the remaining units, the excess flow (containing minimal solids) reports to the overflow launder which is returned to the
