The senarator is equipped with a P for supplying the carrier gas and the source material. Suspended material in the gas flow enters the working zone L 10, 11, is reflected from them and moves

    in the direction of rotation P 1. In the case of s. On the inside of L 10, 11, the first separation of the suspension is carried out. Large particles move outwards again towards L 10, 11, are reflected from them, enter funnel 12 and are discharged through P 13. Leaving the suspension enters working zone L 3, where large particles move from P 1 towards L 10, 11 and enter the funnel 12. The small fraction is discharged through P 7, 1 Il.

    This invention relates to the field of mineral processing.
    The aim of the invention is to improve the accuracy of separation,
    The drawing shows a separator, axial section.
    The separator has a rotor 1 mounted rotatably around a vertical axis YU. The rotor 1 is driven by a PO1-SUS engine (not shown) through shaft 2, the rotor 1 is equipped
    blades 3 mounted on ring nga: neck 4 and top 5 plates. Top plate 5. Equipped with a central hole 6, communicating with the nozzle
    com 7 for discharging the separated fine fraction suspended in the gas. Along the perimeter of the rotor 1, there are two sets of 8.9 guide vanes 10 and 11, installed with the possibility of independent movement,
    Under the rotor 1 and the blades 10 and 11 directed by them, there is placed a funnel 12 equipped with a nozzle 13 for discharging the coarse fraction. The separator is enclosed in housing 14, which may be the upper part of the housing of a vertical roller mill.
    The guide blades 10 are provided with shafts 15 mounted with the possibility of rotation on the upper part of the housing 14 and in the fixed ring 16 placed between the total sets 8.9, and the guide blades 11 are equipped with the shafts 17 mounted with the possibility of rotation on the upper parts of the funnel 12 and in the ring 16.

    ABOUT
    Each set 8.9 of the guide vanes 10 and 11 is provided with an independent movement drive, made in the form of gear wheels 18 and 19 mounted on one end of the shafts 15 and 17 and driven in rotation through the gear ring 20, 21.
    The separator works as follows.
    Pa; the material suspended in the separator suspended in the gas stream is fed up into the housing 14 to the zone of the rotor 1 (indicated by arrows). Then the material enters the working area of the guide blades 10 and 11 of both sets 8, 9, and as a result of the inclination of the guide blades 10 and 11, the suspension is reflected and moved in the direction of rotation of the rotor 1. Thus, both the guide blades 10 and 11 and the rotor 1 provides rotation of the slurry and, due to the centrifugal force generated by the rotation, the first separation already takes place on the inside of the guide blades 10 and It. Just inside the guide blades 10 and 11, large particles of the suspension move outwards again towards the guide blades 10 and 11, where the particles are reflected, as a result they fall into the funnel 12. The rest of the suspension containing fine particles of the starting material enters the working area of the blades 3, where another particle separation process takes place. The remaining coarse particles also move as a result of centrifugal force from the rotor 1 to the outside towards the guide vanes 10 and 11 and then fall into the funnel 12, from where the coarse particles are released for their intended purpose.
    The separated fine fraction, which is still suspended in the gas stream, moves with the gas through the rotor and as the desired product is withdrawn through the nozzle 7, made in the upper part of the separator.
