PTMS MAGNETIC SEPARATOR

what is magnetic separation in chemistry？

The device that sorts iron minerals from raw materials by using the magnetic field's attractive properties to ferromagnetic materials is called a separator, also called a magnetic separator. The basic condition for achieving the sorting purpose is that the attraction force of the magnetic field to the ferromagnetic substance (F) is greater than the resultant force (Fc?, also called competitiveness) that prevents the magnetic particles from being separated. The Fc includes the gravity, centrifugal force, and inertial force of the ferromagnetic particles. And the resistance of fluid power and so on.

When the slurry is de-ironed, the inertial force and fluid resistance are the main part of the competitiveness. At this time, the fluid resistance

Fc=3πηdv

Where: η-η mud viscosity

D-mineral particle diameter

V-mud flow rate

According to the expression of Fc, the viscosity of the slurry, the size of the iron mineral particles and the flow velocity of the mud directly affect the magnitude of the competitiveness, that is, the effect of removing iron. Therefore, when using the iron remover, carefully grasp the "four degrees" (concentration, viscosity, speed and particle size) of the slurry. The particle size should be determined by the pore size selection of the vibrating screen; the speed is directly related to the flow rate; the viscosity is related to the concentration, properties and additives of the slurry; the concentration is related to the moisture ratio.

A practical iron remover should have the following three conditions:

1 a sufficiently strong magnetic field source (F>Fc);

2 sufficient contact area to protect the opportunity and place to absorb prey;

3 Clean (separate) the ferromagnetic impurities that have been absorbed in a timely and effective manner.

(Cleaning is the key to effective iron removal)
