Magnetic Separator

Magnetic particles in a magnetic separator magnetic field, besides the magnetic effect, but also by the competitive effect. Competitiveness can be defined as all the mechanical force and magnetic force in the opposite direction, including gravity, centrifugal force and inertia forces and hydrodynamic drag. During the process of magnetic separation, magnetic force is the force collector magnetic particles, also known as the magnetic collector; competitive force is the magnetic particles from the pole, also known as detachment force. Obviously, magnetic and non-magnetic particle separation is necessary for the magnetic force of magnetic particles than competitive. To make two different kinds of magnetic particle separation, necessary conditions are, the stronger the magnetic force of magnetic particles should be more than competitive, the magnetism of weak magnetic particles should be less than competitive. As mentioned, there can be no absolute purity in the practice of magnetic separation of magnetic and non-magnetic products, in addition to product purity not adherent effect of monomer dissociation, a single magnetic particles into non-magnetic products, some non-magnetic particles into the magnetic products. The former case, led to recovery of magnetic components declined, mainly due to the size of the magnetic particles are too small, magnetic force is not sufficient to overcome the resistance of fluid competition; latter magnetic products are lower grades causes are mostly there is strong interaction forces between particles, finer particle size, slurry density greater interaction between particles will be more obvious.

Electromagnetic coils to make magnetic separators and the polarity of magnetization of the iron core, which generates a magnetic field around it. Between the poles of the magnetic field and particle magnetization, magnetic and magnetic and non-magnetic particles are only naked eye weak magnetic effect, resulting in separation of magnetic particles and non-magnetic particles. Therefore, further understanding of the magnetization of the material, including magnetic structures, magnetic behavior of magnetic field and magnetization level measurement, it is essential to understand the nature of magnetic separation process.
