The invention relates to the field of separation of bulk materials by size and density and can be applied in the mining, chemical and construction industry. And in agriculture.

The purpose of the invention is to improve the quality of the separation products by controlling the concentration of the coarse fraction.

Fig. D shows a separator, a longitudinal section, with the position of the discharge device for a large fraction outside the drum; figure 2 - the same, in the cavity of the drum.

The separator consists of a drive drum 1, a fixed disk 2 rigidly fastened to the loading tray 3 and a drum 1 fixed in the cavity 1. With a gap "in the lower part, disk 4 having an eccentrically located opening 5 and installed with the possibility of rotation in the end part of the drum. A second disk 6 with an eccentric hole 7 is rotatably mounted in the hole 5, in which the unloading device 8 in the form of a hollow cylinder with a spiral 9 in the internal cavity rigidly attached to the cylinder walls is installed with the possibility of rotation and translational axial movement. The device is equipped with chutes 10 and 11 under tools 8 and 12 for transferring small 13 and coarse 14 fractions to the process stream. For turning

The disk 4 has a worm gear (worm to 15 and worm crown 16). The drum 1 is mounted on support rollers 18 by means of a bandage 17. Clamping screws 19 are provided for fixing the disk 6 in the desired position relative to the disk 4. A pneumatic or hydraulic cylinder 21 is mounted on the nozzle 20 of the disk 6, the stem 22 of which is pivotally connected to the ring 23 installed in an annular groove 24 on the surface of the cylinder 8. On the platform 25 of the ring 23, an actuator 26 is mounted to drive the cylinder 8 into rotation by means of gear (or friction) wheels 27 and 28, one of which is mounted on the drive shaft 26 and the other on the discharge cylinder 8.

The device works as follows.

The drum 1 is reported to rotate, and the bulk material is continuously fed through the loading tray 3 for separation. Under the action of rotation, it is located at the bottom of the drum 1 and is poured in the waterfall mode, while the coarse grains are concentrated due to natural stratification of almost 9 centers of gravity of the section. Fine grains are removed along the yel-i bu 1. To remove the coarse fraction, the axis of the cylinder 8 must be aligned with the concentration region of the coarse fraction in the cross section of the material being transferred.
