Description

Technical Field

[0001] The utility model relates to the technical field of ore unloading, in particular to a strong magnetic machine ore unloading device. Background Art

[0002] The strong magnetic machine in the main plant of the ore dressing operation area is the key equipment for ore dressing.

At present, the strong magnetic machine is mainly composed of a pulsating mechanism, an exciting coil, an iron yoke, a rotating ring and various hoppers. The vertical ring is filled with magnetic conductive medium. When sorting materials, the rotating ring rotates clockwise and flows through the rotating ring along the gap of the iron yoke. The magnetic particles in the rotating ring are adsorbed on the surface of the medium. After being brought to the top magnetic field-free area by the rotating ring, they are flushed into the magnetic product bucket by the unloading ore water. The non-magnetic particles are discharged from the non-magnetic logistics outlet to achieve the sorting of magnetic particles and non-magnetic substances.
