Реферат

The use of pneumatic machines at concentration factory of GRK Bystrinskoe in recleaner flotation at high concentration capacity is a promising trend against the background of the reduced content of valuable components in the initial raw materials. An important criterion of a machine efficiency is the technical-and-economical assessment of the machine operation, which, in its turn, depends on the energy cost of aeration and dynamic feed of pulp, which summarily ensures improvement of the quality and quantity factors. The main distinguishing feature of the pneumatic-type flotation machines is aeration and mixing of pulp using compressed air. The construct of the pneumo-mechanical flotation machines enables selection of minerals of the coarse grinding, which allows a wider range of coarseness of floated grains as compared with the pneumatic machines. It should be emphasized that the use of the pneumatic machines in recleaner flotation enables reaching comparable or higher quality and quantity factors within a shorter time. This article presents the experimental data on the efficiency of different-type flotation machines in recleaning operations.
