SELECTION OF MECHANICAL FLOTATION EQUIPMENT
A forced air flotation machine typically has stable, consistent froth flow over the lip at the top of the machine. This is because the rotor is located at the bottom of the and the tank distance of the rotor to the froth zone minimizes turbulence in the upper region, which is conducive toa stable froth zone. As previously

Some gas dispersion characteristics of mechanical flotation machines
The last 10 years have seen significant advances in the measurement of so-called gas dispersion properties in flotation machines, namely: gas superficial velocity (or simply gas rate) (J g), gas holdup (ε g) and bubble size (diameter, D b).From these can be derived the bubble surface area flux (S b = 6J g /D b, where D b is usually the Sauter mean diameter, D 32).
