The magnetic field produced by the PTMS magnetic separator is one of the important factors of the magnetic separation process. According to the different needs of the mineral dressing, we need a reliable analysis of the magnetic separation equipment and process of the PTMS magnetic separator, in order to choose a reliable process technical support, the following is your detailed analysis as follows:

Mineral magnetic difference is the basis of magnetic separation. Mineral magnetism can be measured, according to its magnetic strength can be divided into three types of minerals: ① strong magnetic minerals, such minerals are not many; (2) weakly magnetic minerals, the number of such minerals is more; ③ Non-magnetic minerals, most of the non-metallic minerals and non-ferrous minerals belong to this category.

In the magnetic field of PTMS magnetic separator, the magnetic force of strongly magnetic minerals is the largest, the magnetic force of weakly magnetic minerals is small, and the non-magnetic minerals are not affected by the magnetic force or weak force.

The magnetic field of PTMS magnetic separator is a necessary condition to realize magnetic separation. PTMS magnetic separator is the best choice. The magnetic field can be divided into uniform magnetic field and non-uniform magnetic field. The degree of non-uniformity of the magnetic field is expressed by the magnetic field gradient. The magnetic field gradient is the change rate of the magnetic field intensity along the space, that is, the change quantity of the magnetic field intensity per unit length. The larger the magnetic field gradient is, the greater the degree of magnetic field inhomogeneity is, that is, the larger the variation rate of magnetic field intensity along space is. The magnitude of the magnetic force on a magnetic particle is proportional to the product of the strength of the magnetic field and its gradient.

If the magnetic field gradient is equal to zero (the magnetic field gradient of a uniform field is equal to zero no matter how strong the field is). The magnetic force of the magnetic ore particles is zero, magnetic separation can not be carried out. Therefore, PTMS magnetic separators are not uniform magnetic field.

In the process of magnetic separation, ore particles are affected by a variety of forces, in addition to magnetic force, and gravity, centrifugal force, water force and friction force. PTMS magnetic separator is the best choice. When the magnetic force of the magnetic particles is greater than the sum of the other forces, it will be sucked out or deviated from the material flow, become magnetic products, the rest of the non-magnetic products, to achieve the separation of different magnetic minerals.
