Abstract

The invention relates to air methods of mineral processing and is intended for the separation of fine-grained bulk materials depending on the shape and size of the divided grains, in particular the waste products of carbonate materials. The purpose of the invention is to improve the performance of the device and the quality of separation. The device comprises a separation chamber 6 with a grill 17. In the lower part of the chamber 6, the chutes 7 and 8 are installed for the separated fractions. A feeding device 1 is located above the chamber 6, in the opposite side walls 20 and 21 of the chamber 6 there are air supply device (runway) 3 with a discharge pipe consisting of parts 4 and 5, and a cyclone. Between chutes 7 and 8 and above them there is a rotary gate 18. In the discharge pipe between parts 4 and 5, a heater 19 is installed. The grille 17 is made of an odd number of core chain pieces attached to the side walls 20 and 21 of chamber 6 above the runway 3 discharge pipe AT THE AREA, IT'S ALL 6. THE RAW OF RAW MATERIALS IS SHARED BY LATTICE 17 ON SEPARATE VERTICAL LAYERS, BETWEEN WHICH GROWN NARROW GAPES. IN THESE RINGS, A COMPRESSED AIR FLOW FROM Runway 3, heated by a heater, 19 is directed. At the same time, the air is separated from the raw material with simultaneous drying. 2 Il.

In the process of operation, the supply nris-method-: 1e} 1e 1 feeds the raw material into the |) separation chamber (). The flow of raw materials is divided by dividing penieTKoii 17 into separate verticals, with 1i, between which narrow 1ts, ty are formed. In this case, the notes of compressed air from () the air duct of 1H) of the air inlet 3, heated by a heater 19, are used. At the same time, the air senilica C1) 11) of the simultaneous heat source is wound.

The moisture content of the dolomite raw material is different and depends on the size of the fractions: iamenyena for the K-20 mm fraction and the most (), - 1y1a for the O-5 mm fraction. In I1P) cesèse seiariatsii, the metal fractions are separated by an air stream and the particle is carried away i) the inlet pipe 13 and the cyclone 12, where it is heated and dried, while the moisture content of the fines decreases from 12-15 to 9-10%, while in large fractions g qi x remains almost unchanged at 5-6%,

Part of the small fractions of size 5-10 mm is deposited in the separation chamber 6 at the Novorotny 11Jiber 18 and enters the chute 8 of the lower sieve 11 of the screen 9. Most

 coarse fractions with a size of 10-20 mm, almost never deflected by the air flow, enter the chute 7 and further on the sieve 10 of the same screen.

From cyclone 12 through automatic

5 shutter, the suspended fine fractions are periodically dispensed into the finished product bin. A part of small (|) cancer 11.iy, separating them from large, in the process of screening, sieves 10 and II vibratory 1-rohot 9 is here.

 the screen does not enter the hammer mill (not shown) for further processing, being well dried (up to 5-6% moisture).

Thanks to the separation of the incoming syr on the gri part, the screening mode is much easier compared to when all the raw materials are placed on the screen. A sieve I) gets the material completely cleaned of small fractions, and the sieve 1 1 partially cleaned of small

0 fractions 11 and dry Because of this, sieves are not clogged with small and dusty fractions and work efficiently and productively.

Efficient separation of the raw material in the separation chamber 6 is ensured thanks to the pressure of the material after its passage through the separation 17 effect of the multistage ejector. At the same time, energy is spent not on the deviation of large fractions, but on leaching and absorption of fines from the voids and mazes of the flow of raw materials.

This ensures unimpeded passage of oversized pieces of raw material b, for example, the composition of, 1k) pi 17x separation grid 17, Corner pieces roll down but the chain segments from the center of the separation chamber 6 to its side walls, where the shells are sufficient for any pieces. At the same time, the deposition of wet dorsal () fractures on the core chains is eliminated due to mobility and the interaction of their links.
