Abstract
A flow self-adjusting type mine diameter grading apparatus applied to tailings recovery includes a driving device, a tailings conveying device, a flow regulating device, and a mine diameter grading device arranged in sequence according to working procedures. A motor of the driving device is configured to drive an axial flow impeller and a spiral concentrating wheel to do work through a main shaft connected with the motor. The tailing conveying device includes a tailing water main pipe, a tailing water pipe, an ore blowing pipe, an ore suction pipe, an ore conveying main pipe and ore conveying branch pipes. A flow regulating valve of the flow regulating device is configured to rotate along with the main shaft and move up and down according to change of a rotational speed. The mine diameter grading device includes first-level to fifth-level mine diameter grading plates and first-level to fifth-level mine diameter storage bins.
