The linings on the shaft, rotor, and stator should be inspected in each shutdown for wear, cracks, and chunk type failure. Components with severe damage should be removed and replaced. Concentrically of the rotor inside the draft tube or stator should be checked.
The purpose of the rotor in a mechanical flotation cell is two fold. First, it must perform the task of a pump in maintaining the suspension of solids throughout the lower portions of the tank. Second, it must produce the required quantity of fine air bubbles and effectively disperse them into the slurry.
Increased fine particle recovery Specifically designed to maximise fine particle recovery, the Dorr Oliver flotation cell is the most energy efficient, technically advanced, forced air flotation machine on the market. Its air dispersion capabilities exceed all competitive forced air designs an important consideration for fine particle recovery.
A flotation cell of the type comprising at least one froth removal edge and a rotor and stator adapted to be immersed in the liquid to be flotated, in order to direct the surface flow in the flotation cell towards its removal edge or edges, the clearance between the rotor and the stator, as seen in the rotation direction of the rotor, widens in that rotational sector or those rotational ...
Flotation Cell Design and Flotation Flowsheets The Sub A Operates in three zones: in bottom zone, impeller thoroughly mixes and aerates the pulp, the central zone separates the mineral laden particles from the worthless gangue, and in top zone the mineral laden concentrate high in grade, is quickly removed by the paddle of a Denver Sub A Cell.
