Effect of particle size and shape of mineral on the process of removing iron from PTMS magnetic separator
Time: Nov 07,2023

water cooled electromagnetic Separator for Silica Sand

Influence of particle size: The magnetism of large magnetic particles is generated by the movement of magnetic domain walls and the rotation of magnetic domains, in which the domain wall movement is the main. PTMS magnetic separator During the process of iron removal, the number of magnetic domains in each particle decreases with the decrease of particle size. During magnetization, the movement of magnetic domain walls is relatively reduced, and the rotation of magnetic domains gradually plays a dominant role.



PTMS MAGNETIC SEPARATOR

When the particle size is reduced to the single domain state, there is no movement of the magnetic domain walls, and the magnetic properties of the ore particles are completely generated by the rotation of the magnetic domains. The energy required for domain rotation is much larger than that for domain wall movement, so with the decrease of particle size, the specific susceptibility of magnetite decreases and the coercivity increases. The influence of particle shape on PTMS magnetic separator. Different shapes of mineral particles show different magnetic properties when magnetized in the same magnetic field.



what is magnetic separation in chemistry?

The specific magnetization and magnetic susceptibility of elongated ore particles are larger than those of spherical ore particles. The specific magnetization and specific magnetization of cylindrical magnetite with the same composition and content are related to their length under the same magnetic field intensity, and the larger the length of the ore particle, the greater the specific magnetization and specific magnetization. PTMS magnetic separator can remove the iron (FE2O3) inside.
