摘要

The device has a dispersion nozzle (10) viewed in a flow direction of suspension. A suspension nozzle (3''') is discharged in a mixing chamber (4). A mixing tube (5) is provided adjacent to the mixing chamber. Gas supply lines (6a, 6b) supply the gas into the mixing chamber. The suspension nozzle includes a number of gas channels (31) connected to the supply lines. The gas channels are discharged at a front side (3a''') of the suspension nozzle. Gas control valves are associated with the gas channels for dosing a volume of the gas supplied to the suspension through the gas channels. Independent claims are also included for the following: (1) a method for operating a device for dispersing suspension with gas (2) a flotation machine comprises a housing (3) a method for operating a flotation machine.
