Description

For the enrichment of mineral ore at the processing plants, the abrikas are now open: some rasprostraniyu received mechiiiiiecKHo, Pnsa. Mechanical, pneumatic, aero-lift and other flotation. They have advantages, well-known,, 1 имеют имеют имеют недостатки недостатки недостатки недостатки недостатки недостатки,,,, for example. High eper | Goemkost process of flotation, inzku dispersion of air bubbles. In addition, mechanical and pneumatic mechanical flotomashm.n are characterized by high impeller wear and the absence of a quiet Pulp zone in the kaimer, which is necessary for shaping the miperali: 30: 1 foam and a useful product to be removed to P0 up,).

Known flotation machines made from zibra by cyan aerators allow for a low-frequency vibrations to obtain a calm sunrise, a pulp flow, and a thin air bubble.

A distinctive feature of the proposed flotation maschine with vibrating aeratramp is the presence of an additional chamber made of four compartments: pltani, unloading and two unwelded air dampers, and a small one in the aerator of an elastic system: valves.

Flotation machine works as follows. Riser iotokom siizu up uc .hodna pulp through compartment I nitani threshold and enters the chamber 2 relative flotatsioshpyu opokoynym 1I, rav1yumer: nym stream where subjected .vibratsioepo mu Effects aeratoroZ 5 which with po1moschyu vibroprieoda 4 perform periodic asolebapi in vert ikalnoy plane. In case of aeration, the aerators work not only as Efficient Hi), i.e. air vapor dispersers, as well as pump pumps that simultaneously provide a non-syrupic pulp circulation down through the zero valve system 5.

Only once with the circulation of the pulia through the aerator, through valve 6, air is supplied, which, when vibrated by the aerator, is excited, dispersed and ejected by the DO flot pulp in fine pulverized bubbles along the entire length of the valve.

As a result of shgrapiopia agitation and aeration from the sides of the aerators, symmetrical upward flows of pulp saturated with mi- peralized by bubble bubbles that float to the surface of the n in the form of foam are removed to the foamy pits 7.

In order to remove the product from the vacuum suction unit, the side singing outlets are fitted with two removable air dampers 6 on the top, and the bottom is equipped with hermetically sealed air. 9, edging up the so-called pipe: c.

With a non-military posture into the flotation machine, the new mana-la-pulpa thanks to the agitates: and in the flotation chamber of the inner chamber, the trajectory moves without settling down the line from the entrance to the exit, npaiqe.M tails and sands are removed through the top and bottom of the bottom and the bottom of the bottom and bottom. / 7: In the compartment 12 I discharged the part of the flotation of Bibradiole 3 Bib, p01P1 of the harbor: a | Prazlenko action, carrying frame 13 with.
