Competitiveness of the Magnetic Particles From the Magnetic Force

Magnetic particles in the magnetic separator, except by the magnetic force, but also by the role of competitiveness. Competitiveness can be defined as the direction opposite to the magnetic force of all mechanical force, including gravity, centrifugal force, inertia force and the hydrodynamic resistance and the like. In the magnetic separation process, the magnetic force of the magnetic particles in the collector, the collector also called magnetic force; competitiveness of the magnetic particles from the magnetic force is also known from the force. Obviously, the necessary condition for the magnetic particles and non-magnetic particles are separated from the magnetic particles is greater than the magnetic force competitiveness. To make two kinds of different magnetic particle separation, the necessary condition is that a strong magnetic force of the magnetic particles should be more than competitive, weak magnetic force of the magnetic particles should be less competitive. It should be noted, in practice there can be magnetic magnetic absolutely pure products and non-magnetic product, except the monomer of the living body does not influence the dissociation product purity, the number of magnetic particles mixed with the monomer in the non-magnetic product, some of the non-single magnetic particles mixed with magnetic products. In the former case, resulting in the recovery of the magnetic component, due primarily to the magnetic particle size is too small, the magnetic force sufficient to overcome the resistance of the fluid such competitive; latter case leads to decreased quality of magnetic products, the most likely cause of the particles there is a strong interaction between, the finer the particle size, the greater the concentration of the slurry, the more obvious interaction between the particles.
Can solenoid magnetic core and the magnetic poles of the machine, generates a magnetic field around it. Between the magnetic field and the magnetization and mineral particles, assuming magnetism, and thus generating a magnetic force; magnetic mineral particles can not receive a weak magnetic force of not visually observed, leading to the separation of magnetic particles and non-magnetic mineral ore particles. Therefore, a better understanding of magnetic materials, including structural magnetic material, measuring behavior and the degree of magnetization of the magnetic field, magnetic separation process of understanding the nature is essential.
