Abstract

This invention relates to the beneficiation of minerals. The goal is to intensify the conditioning process and reduce the consumption of reagents due to the differentiated supply of reagents in the pulp fraction of various sizes. The device comprises a stationary cylindrical conditioning chamber 1, under which a funnel 10 is located coaxially for collecting pulp. Inside the chamber 1 there is a coaxially arranged rotor 2 in the shape of a hollow cylinder with a bottom 7 made in the shape of a cone, which is installed with its top up. In the wall of the rotor 2, discharge channels 3 are arranged one above the other. A hollow shaft 4 is connected to the rotor 2 coaxially and on top. Inside the shaft 4 there is a coaxially located branch pipe 8 for supplying reagents with outlets 9 connected to the channels 3. The pulp flows through the shaft 4 the inside of the rotor 2, where due to the rotation it is thrown to the walls and through the channels 3 in the form of jets it is directed to collide against the fixed wall of chamber 1. Stack through the walls of chamber 1, the pulp is collected into the funnel 10, from where it is sent to the flotation. The reagents through the pipe 8 and the taps 9 are fed to the channels 3. 1 C.p. f-ly, 2 ill.

Description

The invention relates to the enrichment of minerals by the flotation method, in particular, to devices for preparing pulp for the flotation process, and can be used in the processing of various types of mountain raw materials.

The purpose of the invention is to intensify the conditioning process and reduce the consumption of reagents due to the differentiated supply of reagents in the pulp fraction of various sizes. ,

Fig. 1 shows a device for conditioning ore pulp with r.eagents, frontal section; figure 2 - node I in Fig, 1.

The device consists of a fixed cylindrical conditioning chamber 1, inside which a rotor 2 is coaxially arranged in the form of a hollow cylinder. In the wall of the rotor 2, discharge channels Z are made one above the other. To the rotor 2, a hollow shaft 4 with openings 5 in the lower part is attached to the rotor 2 to supply pulp into the internal cavity 6 of the rotor 2. Bottom 2 of the rotor 2 made in the form of a cone, set the top up. Inside the hollow shaft 4 on its axis there is a nozzle 8 for supplying reagents with outlets 9 connected to exhaust ports 3. Under the fixed conditioning chamber 1, a funnel 10 is installed coaxially with a funnel 10 for collecting pulp treated with reagents.

The device works as follows.

Ore pulp through the hollow shaft 4 and the holes 5, reflected from the bottom 7, enters the inner cavity 6 of the rotor 2. The latter is brought into rotation by a rigid connection with the hollow shaft 4 rotated by the drive. Due to the centrifugal the forces arising due to the rotation of the rotor 2, the pulp is pressed against its wall and is thrown into the conditioning chamber 1 through rows of exhaust channels 3, while the large granular, medium-sized and fine-grained fractions of the pulp are ejected from, respectively

the top and bottom rows of the discharge channels 3. The reagents from the nozzle-8 through the taps 9 are directed to the exhaust channels 3. In this case, if necessary, the reactants can be fed only into one or two pulp fractions due to the overlapping of the taps 9 in some either in height.

The ends of the taps 9 are located with a certain gap relative to the beginning of the discharge channels 3, so that when the pulp flows from the rotor 6 cavity 6 outward, the reagents from the taps 9 are sucked into the channels 3 due to their ejection by the flow of the pulp. Departure from channels 3, pulp jets at high speed hit the walls of the fixed conditioning chamber 1. With this, conditions are created for the selective interaction of the reactants with the dehydrated surface of the particles. The cone-shaped form, the bottom 7 of the rotor 2 prevents its silting. From the walls of chamber 1, the slurry flows into the funnel 10, from where it is sent to flotation.
