The pulp enters K 2 through P I, Strong large particles along the wall of K 2 thin in K 3 onto the groove 8 for large classes, the average size of particle through the gap between the middle and lower cones 6 go to K 3 to chute 9, the highest thin class through the gap between the middle and upper cones through pipe 7 to P 4; The middle and large classes of mineral particles are treated with reagents K 3 and enter P 4, 1 or 10 .

one

The invention relates to the processing of minerals, namely, devices for conditioning the flotation pulp before the flotation process, and can be used in the processing of nonferrous and ferrous ores, coal, mining and chemical raw materials.

The aim of the invention is to increase the efficiency of the process by sowing due to the improved division of the N HepanMftix particles of flotation pulp into three or more narrow classes and their separate treatment with flotation reagents,

The drawing shows an apparatus for conditioning a flotation pulp, the general type,

The apparatus for conditioning the flotation pulp consists of a loading device in the form of a tangential power supply pipeline 1, a separation chamber 2 located in the upper part of the apparatus, a conditioning chamber 3 in the middle part of the apparatus, a displacer-slider 4, a regulating mechanism 5, several truncated cones with diffusers along the bottom edge, omka 6, located in the separation chamber one above the other along the axis of the apparatus, the middle cone being vertically displaceable, pipe 7 for tone classes, the axis of which coincides with the axis of the conditioning chamber, and the walls are guiding for the movable

a cone 6, coaxially arranged screw troughs 8 for a large class, and 9 for a middle class large-, ti attached to nozzle 7 for thin classes, pipe 10 for reagents.

The apparatus for conditioning the flotation pulp works as follows.

The original pulp of the tangential feed line 1 enters the separation chamber 2, inside which a cascade of truncated cones with diffusers along the lower edge 6 is located in the center. The middle cone can be moved using a regulating mechanism 5. The displacement allows you to adjust the gaps for draining flotation pulp with particles certain size classes for their intended purpose. The mineral particles in the pulp, under the action of centrifugal forces and gravity, are divided in a separation chamber into several size classes. Large particles, attached to the outer wall of the separation chamber 2, are lowered and enter the conditioning chamber 3, which has a row of coaxially arranged screw troughs, on the trough 8 for large classes.

The thinnest class is made in the upper part of the separation chamber 3 and, through the gap formed by the upper and middle cutoff of the truncated cone 6, is directed the straight pipe 7 for the thinnest 314474

owls directly to the unloading

a device in the form of a displacement puller A.

The middle size class is separated in the middle part of the separation chamber and, through the gap formed by the middle and lower truncated cone 6, is also sent to the conditioning chamber 3 to the corresponding chute 9. In the chutes 8 and 9, the particles are directed to the discharge device in the form of a puller. four,

In the conditioning chamber 3, the pipeline 10 supplies flotation reagents, the flow rate of which is regulated in proportion to the adsorption capacity of the mineral particles of the selected size class.

Thus, mineral separators of all sizes of size go to mixing separator 4, where they are mixed, transferring reagents from large and medium size to fine, and then the pulp is distributed through flotation machines.
