Description

The invention relates to the separation of materials by thickness and may be used to classify materials in various areas of the type of material, for example, in the mica industry.

The purpose of this invention is to increase the efficiency of sorting,

FIG. 1 shows the proposed device a longitudinal section; in fig. 2 - landfill frame; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - suspension assembly.

The sorting device consists of a hopper -1, two frames 2 with rolls 3 and 4s mounted on them, the rolls 3 being installed with the possibility of free rotation, and the rolls 5 are firmly fixed to the balance 5, Adjusting shims 6 are installed under the rolls 3 fixed on trunnions 7 and having the ability to adjust the angle of inclination by means of adjusting bolts 8 Under the frames 2 on the axis 9 a vibrator is fixed. On torsional vibrations with suspension 1 and a limiting sleeve 12, bins 13 are located on the sides of the vibrator 10 th product and bunkers 14 undersize.

The frames 2 are free in, centered through the axis 9 on the suspension 1, which has three flexible branches 15 evenly spaced around the circumference and providing the connection of axis 9 with the housing.

The limiting sleeve 12 fixes the vertical position of the oscillating masses of the structure, and during the operation of the vibrator: About torsional, fluctuations limits the deviation of the axis 9 to the vertical position of the vertical position. The suspension 1 fixes the position of the oscillating masses of the device, and when the vibrator area is 10 torsional vibrations .cnocoB, the transmission of torsional vibrations from the vibrator 10 to frames 2 is possible.

Sorting device works as follows.

The mica crystals 16 from the feed hopper are distributed on the frames 2, the working surfaces of which are formed by the rollers 3 and 4 arranged in two parallel planes, the frames 2 are freely suspended through the axis 9 and the limiting sleeve 12 on

cable suspension 11 and perform oscillatory movements in the horizontal plane from the vibrator 10 torsional vibrations. Vibrator 10 torsional, oscillations simultaneously imparts a swinging motion to unbalances 5, rigidly connected with the axis of the rolls 4. At the same time, the oscillations of unbalances 5 turn the rolls 4, which are freely attached to the bearings, alternately in one direction or the other side j thereby creating movable moving dv / yus working surface on the frames 2, and the rolls 4 on this surface are rotated alternately

5 in opposite directions. In this case, the crystals 16, falling between the rolls 3 and 4 J, receive the necessary orientation relative to the slit of the wedge, and the alternate turning of the rolls 4 to different sides and free fixing on the bearing supports of the rolls 3 contribute to the passage of pyastin mica, which are thinner than the slit (5, into the hopper the undersize product.

At the same time, the centrifugal forces transmitted from the vibrator 10 torsional vibrations to the frame 2, promote the flow of mica crystals 15 in the direction from the loading hopper 1 to the bunker 13 of the shear product, into which the crystals fall, the thickness of which is a large gap width of the flow velocity crystals 16 mica regus; It is also tilted by the frames 2, mounted on the trunnions 7, with the help of adjustment bolts 8. The width of the slots (5 can be adjusted by raising the rolls 3 with the help of gaskets 6.
