One of the most important aerohydrodynamic indicators of any flotation machine is aeration. The concept of aeration is identified with the quantitative ratios of the air and liquid phases, as well as the 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 non-uniformity. Air bubbles of various sizes pass through any point of the chamber, able to increase in size as they rise and coalesce. The non-uniformity 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 under the condition of a rational design of the main components and their linking into a single complex, subordinated to the fulfillment of the required technological and technical‑economic performance indicators of the machine.
