    The invention relates to a flotation machine designed for floating minerals from sludges containing coarse particles. The flotation machine comprises a rotor (3) and a stator (2) provided with actuator machinery and auxiliary equipment (7, 8, 9). The bottom (14) of the stator (2) is solid and the stator-rotor mechanism is located within the cell apart from the cell bottom (10). The feed inlet pipe (12) is connected to the cell so that the feed is directed towards the mixing zone of the rotor flow.

    On the casing, a device 12 for supplying the raw material is tangentially mounted and connected to its floor. Adaptation 12 m. made in the form of several nozzles uniformly mounted on the housing around the rotor, which allows using the volume of the housing part 1 in the mixing zone, the device is able to handle the feed mixtures with very
    large pulp densities In this case, large particles that never remain in suspension can be quickly separated from the supplied pulp. Plate 1 prevents the lifting of large particles to the suction zone of the rotor. At the same time, the useless and circulating ringing inside the body G of large particles is eliminated. 2 hp f-ly, 2 ill.
    The invention relates to a flotation machine for the flotation of minerals or other similar materials from pulps containing: 20 large particles.
    The purpose of the invention is to increase the efficiency of flotation of large chasuits of raw materials. ,;
    The device is capable of processing: 25 feed mixtures with very high pulp densities. With the help of the proposed device, very large particles that never remain in suspension can be quickly separated from the DF of the feed pulp. In this case, the circulation of large particles inside the chamber is avoided and at the same time the degree of wear is significantly reduced.
    Figure 1 shows flotation. ,, car, general view; in FIG. 2, the tangent, social and uniform arrangement of the supply pipes for the feedstock.
    Inside the flotation cylinder-conic case 1, a sy- is installed; Q stirring subject including stator; 2 and the rotor 3; The rotor is rigidly connected to the hollow shaft / +, which is mounted on a bearing with the help of bearings 5 and 6; the housing structure. The shaft is driven by the drive 7 by means of a new belt 8, Air is fed into the rotor 3 through the hollow shaft. The air supply means is indicated with 9,
    The entire lower part of the housing is a cone 10, in the form of a cone 10, a hole is made at the lower end i of the cone, provided with a pipe fitting 11 connected to the pipe, along which the waste is discharged from the housing. The position of the feed unit; gj 12 is adjusted to the height of the body so that the feed slurry entering through this device is directed
    Directly to the zone of action of the flow generated by the rotor passing through the blades of the stator 2, an additional positive effect is created when the device for supplying the raw material can be adjusted in an inclined or even completely tangal position on the housing wall.
    Experience has shown that the ability to control the position of the device 12 for supplying the feedstock is important if it is desirable to obtain optimum performance with different types of concentrates.
    The stator 2 is attached to the lower part of the chamber around the rotor 3 by means of bolts 13, so that between the lower part of the housing and the lower part of the stator there remains a free transverse gap, which in practice is equal to several centimeters. The stator 2 is fixed on the plate 1 on the side of the rotor 3, when the source material flows counter to the flow from the rotor and the stator, the large particles are classified so that lightweight floating particles form a suspension, and larger and heavier particles settle directly to the bottom. part of the body. Since the stator is located at some distance from this lower part, large particles can easily slip under the stator and further - to drain them through pipe fitting 11 Plate 1, installed under the stator, prevents the large particles from rising to the suction area of the rotor than eliminating the useless and wear-causing circulation of large particles within the housing. V.. I
    The coarse concentrate is discharged from the housing 1 in the usual manner via the exit edge 15. The recovered auxiliary coarse concentrate is ready to be added to the concentrate recovered during the normal flotation process. The coarse concentrate may also be re-floated. The waste in the form of coarse particles removed from the flotation machine is sent to regrind.
    The best results in practice are achieved using the rotor and stator designs manufactured by Oute Kumpu Oy and available under the trade name OK.
    The tangential arrangement of supplying the raw material helps to create pulp rotation and the best leaching of small particles from the raw material by a stream of pulp coming from the stator 2.
     Making a device for supplying raw materials from several nozzles and evenly positioning them on the body 1 allows the most efficient use of the volume of the body part in the zone of the mixing system,
