A lime feeder includes a metering driving vessel divided into two chambers arranged below a water inlet so that, alternatively one and the other chamber is filled with water and tilts between two end positions. The tilting movement is conducted by a carrier bar fastened in the metering vessel, to carriers that, in turn, drive a disk back and forth. The disk, in turn, feeds lime from a lime hopper with a movement back and forth. The lime powder is thereby brought to fall into the chamber of the metering vessel that has already been emptied. In this way, the lime will be wetted so that when it arrives in the stream of water, it is already suspended, which results in a more efficient dissolving of the lime.--
