The working principle is as follows:

the utility model discloses a design on the basis of bai genno theory and flowing film ore dressing principle and form, its principle is that the different realization of density and the granularity through the mineral grain is selected separately in the compound force field. When ore pulp flows to the side surface of the hemispherical cover from the ore feeding device and is uniformly spread and enters the separation area of the conical surface, the flow state of the ore pulp is in an obvious turbulent flow state, the flowing film of the ore pulp becomes thinner gradually from thickness in the flowing process, the flow velocity is also reduced slowly, and the ore particles are properly loosened and layered on the disc surface under the action of self gravity, the rotation of the disc surface and the shearing repulsion force generated by horizontal vibration. Then the low-speed rotation of the sorting conical surface brings the minerals into a fine selection area with a low-speed water flow area corresponding to the lower part of the involute washing water pipe, brings the minerals with different densities and granularities into corresponding separation grooves in the ore receiving groove, and discharges the minerals through corresponding tailing discharge pipes, middling discharge pipes and concentrate discharge pipes.

4. The separation disc is formed by connecting two conical surfaces with different slopes, ore pulp is uniformly spread out from a hemispherical cover and then flows through the separation disc in a sequence from high slope to low slope, when the separation disc is on the conical surface with high slope, the ore pulp obtains relatively fast flow rate, light minerals enter a separation area of the conical surface with low slope fast flow rate, and heavy minerals are preliminarily enriched on the conical surface with high slope. Then the ore pulp enters a low-gradient separation conical surface for further separation. Compared with the design that the whole sorting tray is a slope, the design can enable light minerals in the ore pulp to enter tailings more quickly, the flow rate of the whole ore pulp is improved, and then the sorting speed, efficiency and sorting precision are improved.

5. The involute washing water pipe adopts the connection design of two sections of involute water pipes with different base circle radiuses, the involute washing water pipe is in accordance with the design of two conical surfaces with different heights and different slopes of the sorting tray, and the two sections of involute washing water pipes with different base circle radiuses correspond to the two sorting trays with different heights and different slopes below the washing water pipe. Because the flow velocity of ore pulp on the two kinds of tapering sorting disks of inner lane and outer lane is different, so the washing water pipe that the involute that the sorting conical surface of inner lane high slope corresponds has less base radius, and the washing water pipe that the sorting conical surface of outer lane low slope corresponds has bigger base radius and the involute is more gentle.

6. The two motion systems of low-speed autorotation and high-frequency vibration are mutually independent and mutually linked and organically combined together, so that the rotating speeds of the two motion systems can be separately adjusted, the speed ratio of the two motion systems can be in the optimal level, the optimal loose-layered state of the flow film is ensured, and the sorting index is improved.

7. The utility model discloses a diameter is the same with the diameter of cambered surface flowing film sorter, consequently can be used with the cambered surface is spread the organic combination of flowing film sorter modularization in follow-up manufacturing, produces new process flow. Compare and hang conical surface concentrator that shakes the utility model discloses miniaturized and simple structure, be convenient for transportation and installation.

10. The bottom surface of the separation trough is welded with two parallel I-shaped steels, and the rotating device and the motor are arranged on the I-shaped steels, so that the whole equipment is integrated, and the transportation, the transportation and the installation are very convenient.

11. Because the ore pulp can have an effect of accelerating flowing under the combined force field of the vibration of the separation disc and the rotary force, if the gradient of the inner cone surface is overlarge, the ore pulp can flow too fast to the separation area with the low gradient, so that the ore pulp separation is insufficient, and the grade of the concentrate is reduced. If the slope of the inner and outer ring conical surfaces is too gentle, the effect of improving the overall flow velocity of ore pulp cannot be achieved, and therefore the separation efficiency cannot be improved. The adoption states the inner circle conical surface slope and is 4 ~ 10, the outer lane conical surface slope is 0 ~ 3 scope, can effectively guarantee the utility model discloses an effect when improving the ore pulp total velocity of flow effect, can also guarantee that the ore pulp is selected separately fully.
