Analysis of magnetic separation column structure and separation principle by red star machine

Magnetic separation column is a new and efficient mineral processing equipment, which can not only fully disperse magnetic agglomeration, but also make full use of magnetic agglomeration. The structure and separation principle of magnetic separation column are analyzed in detail below.

 Magnetic separation column

Structure of magnetic separation column

The magnetic separation column is mainly composed of the host, power supply electric control cabinet and automatic control system. The magnetic separation column adopts special excitation mechanism, the allowable rising water velocity can be as high as 2 ~ 6m / s, its structure is simple, no operating parts, low power consumption and high grade improvement.

Separation principle of magnetic separation column


When the materials enter the magnetic separation column, the magnetic clusters or magnetic chains are pulled downward for many times, and are strongly dispersed for many times, and are affected by relatively strong rotating upward flow force. When dispersing, the connectives and gangues in the magnetic agglomeration are rotated upward, and the hydrodynamic force constantly washes out to form tailings; when agglomerating, the magnetic clusters or magnetic chains move downward under the action of their own effective gravity and magnetic force. After repeated dispersion and agglomeration for 6 ~ 7 times, the inclusion of poor connective and monomer gangue is fully washed out and discharged into concentrate from the lower part of magnetic separation column.

Because of the good separation principle of magnetic separation column, it can effectively separate the low-grade magnetite concentrate, coarse concentrate and middlings of magnetic separation from - 2mm part of low-grade magnetite concentrate, coarse concentrate and magnetic separation middling, and directly obtain high-grade magnetite concentrate, which can be used for production of super magnetite concentrate and concentration equipment before filtration. Through automatic control, the valve of magnetic separation column can be opened and closed automatically, and the intensity of magnetic field can be adjusted automatically, and the maintenance parameters can be optimized to achieve the target value, so as to achieve good quality improvement and impurity reduction.
