SU40905A1 - Asbestos treatment separator - Google Patents

Description

The known difference in the physical properties of needle asbestos and the rocks that include it, such as: serpentine, pyroxene, hornblende, makes it possible to use them on a larger scale with regard to the separation of asbestos fiber from waste rock.

The difference in the properties of asbestos and the rocks included in it consists in a significant difference in the amount of friction between the fibers of asbestos and the coil grains and in the elasticity of the grains of both, which is especially important for separation. In addition, in spite of approximately the same specific weight of them, there is a significant difference in the absolute (volume) weight.

The proposed asbestos enrichment separator is based on the use of these properties. The separator device uses centrifugal force in conjunction with the rotational movements of the round table to separate the asbestos fiber from the hali. The pieces of fibrous asbestos and coil grains, regularly and evenly with each compaction, falling from the feeder onto the upper round table area, will behave differently with each other, being subjected simultaneously to

(6)

centrifugal force and vertical shaking due to the difference in their physical properties of friction, elasticity and absolute removable weight, with asbestos fibers during vertical compaction will be placed on a round table on top of the coil grains, and due to centrifugal force and impacts of radial blades fall into the nearest concentric space, and the coil and olivine (gal) grains will fly off further along the periphery, falling into the outer ring.

In FIG. 1 shows a section of the proposed separator; FIG. 2 - view it from above.

The separator is a circular rotating table 1 mounted on a vertical shaft 2, which receives rotation from the pulley 3 mounted on it, connected with a belt with an electric motor not shown in the drawing.

When the table rotates, there is a conical semicircular protrusion 4 on the underside of the pulley 3 and it encounters a roller 5, fixedly fixed on the support 6; at the same time, the vertical shaft 3 is smoothly lifted, and with it the round rotary table 1 is lifted together to a height equal to

the thickness of the protrusion 4; when the protrusion descends from the roller and further moves, shaft 2 and table 1 fall to their original position each time with one full turn.

For feeding the rotating table, crushed ore serves as a bunker 7 fixedly fixed above the table G. From the bunker ore is dumped into a tray connected to the hopper by a hinge, with the end of tray 8 resting on the rotating table 1. When the table rises, tray 8 also rises, reducing the angle but when the table is suddenly lowered, the pieces of ore located in it are shed, making it easier to descend to the center of the table so that later new pieces of ore can be poured out of the bin.

By measuring with the help of the slit gate for passing the ore from the bunker to the tray, it is possible to supply even and constant power to the rotating table with ore.

The separator table consists of a flat central part and the following two rows aaclonally to the periphery (at an angle of 7 °) of sectors divided between themselves by radial and circular concentric low partitions.

The concentric partitions in the table are designed to keep the fibers from rolling down and to gall and provide them time and opportunity to separate according to their physical properties. During the fall of the table and the rotation of its pieces of ore, not ripening with the fall of the table and not completely carried away by its rotation, will be subjected to lateral impact of the radial partitions, which will fold the pieces, and the latter, due to different between. Physical properties (the difference in the amount of friction, in the elasticity of the grains, in bulk) will fall or closer, near the edge

table (fluff asbestos fibers) or farther from it (serpentine, peridotite, olivine) and, depending on this, either get into concentric receivers 9 or outdoor 10,; To free the table compartments from the separating products, each compartment has hatches and moving scrapers. The latter receive movement from the coupling 11 mounted on the shaft 2 on freely sliding keys, due to which it rotates together with the shaft 2 in the horizontal plane, but does not rise and not fall in the vertical plane, therefore the scrapers 12 attached to it also for the inner chamber and the other for the outer one does not rise and only rakes fiber and galy into holes 14 and 15 through openings, pouring the concentrate and waste rock into different trolleys for delivery or to a warehouse or dump.

The subject matter of the invention.
