Abstract

Device for detonating suspensions of fibrous material by flotation consisting of an annular flotation cell with facilities associated therewith for the suction removal of the foam and for the aeration, as well as facilities for the supply and removal of suspension of fibrous material with respect to to the annular flotation cell, characterized by the combination of the following features: in the annular flotation cell a) the supply port (s) for the suspension of fibrous material are between 300 and 1000 mm below the level of the suspension of fibrous material; b) the withdrawal mouth is approximately at the bottom level and c) the subsequent aeration mouth (s) are disposed 300 to 500 mm above the withdrawal mouth and 300 to 1700 mm below the delivery mouth (s).
