[0002] At present, the sorting chamber of low-temperature superconducting magnetic separation equipment generally includes an effective sorting chamber and an invalid sorting chamber; the effective sorting chamber is filled with a magnetically conductive medium and is the place for magnetic separation of slurry. The magnetically conductive medium generally adopts filamentary steel wool, which can give full play to the high gradient advantage of the magnetically conductive medium under the background of high magnetic field; the invalid sorting chamber mainly plays the role of magnetic balance and slurry channel. The closed space of the invalid sorting chamber will be filled with steel wool with the same filling amount as the effective sorting chamber, which is used to reduce the magnetic force generated when the effective sorting chamber moves under the background magnetic field.
[0003] The above structure will have the following problems when in use: 1.

When the type or filling amount of the magnetic medium in the effective sorting chamber changes, the invalid sorting chamber is difficult to make corresponding adjustments due to its own bulky structure; 2. After the invalid sorting chamber is used for a long time, the steel wool in the invalid sorting chamber will gradually fatigue and break due to the continuous circulating magnetic force, which will cause uneven distribution of the steel wool in the invalid sorting chamber; the above problems will destroy the overall magnetic balance of the sorting chamber of the low-temperature superconducting magnetic separation equipment, and will greatly increase the unbalanced load of the low-temperature superconducting magnetic separation equipment.
