[0005] Therefore, the current magnetic-permeable medium can only achieve millimeter-scale, and correspondingly, the screening of minerals can only capture millimeter-scale mineral particles, while minerals with smaller particle sizes are mostly discharged together with tailings, which undoubtedly causes waste

Embodiment Construction
[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0034] In the present invention, unless stated otherwise, "magnetic particles" refer to particles that can be attracted by magnetized substances, such as iron-titanite particles in minerals; and "non-magnetic particles" refer to particles that are not Particles that can be attracted by magnetized substances, such as some non-metallic mineral particles, etc. The principle of the magnetic separator is to attract magnetic particles by magnetized substances to screen the magnetic particles from the non-magnetic particles.
[0035] According to a specific embodiment of the present invention, the present invention provides a swivel for a magnetic separator, which is ...

The invention discloses a magnetic separator and a swivel thereof as well as a magnetic separation method. A ring-shaped main body (1) of the swivel is internally provided with separation layers (2) which are arrayed at intervals, wherein a mineral channel is formed between the adjacent separation layers; the separation layers (2) are made of non-magnetic materials; a magnetism gathering body (3) is arranged in the ring-shaped main body and a magnetic field gradient pointing to the magnetism gathering body is generated under the state that the magnetism gathering body (3) is magnetized; and particles which pass through the mineral channel and can be adsorbed by magnetism are adsorbed on the separation layers (2). A medium rod in the swivel is replaced with the non-magnetism-conducting separation layers and the soft and magnetic magnetism gathering body is arranged between the separation layers; when micron-grade mineral particles and matched medium particles are added into the mineral channel formed by the separation layers, the magnetic mineral particles are sieved; and the medium particles and the mineral particles are mixed so that the relative friction is reduced, the abrasion amount of the medium particles is reduced, the service life of the medium particles is prolonged and the production cost is reduced.
Description
technical field [0001] The invention relates to components of a magnetic separator, in particular to a rotary ring of the magnetic separator and the magnetic separator. In addition, the present invention also relates to a magnetic separation method. Background technique [0002] At present, the beneficiation operation of ferro-titanium ore can be realized by magnetic separators (such as vertical ring magnetic separators). The vertical ring magnetic separator is mainly composed of a pulsation mechanism, an excitation coil, an iron yoke, a swivel, various mine buckets, and a water supply device. [0003] The swivel of the magnetic separator is set upright, and the swivel is equipped with a magnetically conductive medium, such as a stainless steel rod. When beneficiating, the swivel rotates clockwise. After passing through the rotating ring, the magnetic medium in the rotating ring is magnetized in the magnetic field, and a high gradient magnetic field is formed on the surfac...
