Flotation Machine - an overview | ScienceDirect Topics

Most of the industrial flotation machines used in the coal industry are mechanical, conventional cells. These machines consist of a series of agitated tanks (usually 4–8 cells) through which fine coal slurry is passed. The agitators are used to ensure that larger particles are kept in suspension and to disperse air that enters down through the rotating shaft assembly (Fig. 11.13).

Theory of buoyancy used in perpetual motion

The conclusion is, as both steps 1 and 3 are caused by buoyancy effects, the process should generate an excess of mechanical energy that can be drawn for useful work. This idea is very appealing and more than one patent has been issued for machines of this kind.

How Does a Float Valve Work? | Hunker

Feb 25, 2019· A float switch works by the same principle, but instead of a valve, the float stem activates a switch that actuates a pump. The purpose of the pump could be to fill a tank, as on some well systems, or it could be to empty a pit, as on a sump pump. In a sump system, the switch is wired to turn the pump on, not off, when the water rises.
