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. ...
Задача создания флотационной машины, удовлетворяющей современным требованиям, может быть решена только при условии рациональней конструкции основных узлов и увязки их в единый комплекс, подчиненный выполнению требуемых технологических и технико-экономических показателей работы машины.
