One of the most important aerohydrodynamic indicators of any flotation machine is aeration. With the concept of aeration identify quantitative ratios of air and liquid phases, as well as qualitative characteristics of the size of air bubbles and their distribution over the volume of the chamber. The quantitative side of the aeration process can be expressed through the degree of aeration and the density of the flotation system. ...

One of the characteristic features of the flow in the chamber of a mechanical flotation machine is its inhomogeneity. Air bubbles of varying size pass through any point in the chamber, capable of increasing in size as they float and coalesce. The inhomogeneity is particularly strong in the lower layers of the chamber, where the turbulent nature of the motion prevails. ...

The task of creating a flotation machine that meets modern requirements can be solved only if the rational design of the main components and linking them into a single complex, subordinated to the fulfillment of the required technological and technical and economic performance of the machine.
