USE EFFICIENCY CRITERION FOR FLOTATION MACHINES

The analysis of information sources in the field of the proposed similarity criteria of work flotation machines. Investigation of criteria of efficiency of flotation machines. In the proposed approach the average characteristics of the mass transfer obosnovano the use of experimental – calculation method determining the distribution function of the fractions (range flotation), is based on the use of the generalized equation of flotation kinetics Beloglazova, and designed by V.D. Sekhirev. It is shown that the form of the spectrum and at the position on the axis Km lies all the information about the substance and the efficiency of the flotation machine.
