Abstract

A device for gassing liquids, more particularly from a liquid/solid suspension mixed with flotation reagents, is formed as a supply element 1, through which the suspension 19 to be gassed is passed, formed from at least two butt jointed pipe segments 4, 5 in a plane z-z vertical to its throughflow axis x-x, said segments abutting each other without intermediate space with one end face 2 and/or 3, and at least one of those end faces 2 and/or 3 is formed with grooves 6 (see Fig. 4a, not shown) for the passage of gasification medium. <IMAGE>
