Magnetic separator for separation principle

WD series electromagnetic high gradient coolant magnetic separators selected machine is in pin loaded solenoid line circle, placed with must number guide magnetic stainless steel hair (or plate network) of points selected tank, coil Reed magnetic Hou, makes guide magnetic stainless steel hair magnetization, its surface produced height not uniform of magnetic field, that high gradient of magnetic roll separators field, Shun magnetic material through points selected tank in the of steel hair Shi, will by a and plus magnetic field and magnetic field gradient of product into proportions of magnetic field force, adsorption in steel hair surface, and non-magnetic real directly through magnetic field, after non-magnetic real valve and pipeline, Non-magnetic slot.When the steel wool collectors weak magnetic material reaches a certain level (determined by the technological requirements) and stop feeding.Disconnect Exciter, rinse magnetic materials, magnetic materials by magnetic valves and piping, into magnetic product slot.And then a second job, and the cycle repeats again and again.

Characteristics of magnetic separator

Electromagnetic coils to make magnetic pulley separator 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 grids factory can only receive a weak magnetic effect cannot be observed with the naked eye, leading to 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.

Performance of magnetic separator

Magnetic particles in a dry drum 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;Competitiveness is the magnetic particles from magnetic force, 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 Warbler flourishing May 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;The latter case magnetic products are lower grades of reasons mostly there is strong interaction forces between particles, finer particle size, slurry density greater interaction between particles will be more obvious.

Basics bar magnet

The main magnet is used to filter all kinds of fine powder and liquid, semi-liquid iron impurities and other substances with a magnetic band, now widely used in chemical, food, waste recycling, carbon black and other fields.
Magnets, usually made from rare earth permanent magnets made of magnetic force strength of 6,000 gauss or more, for the absorption of iron magnet, the surface wrapped stainless steel, mainly used in ceramic plants, food plants, chemical and other places.
Common strong performance bar magnets diameter 25mm, currently the strongest diameter 25mm magnet surface magnetic intensity can reach more than 12,000 Gauss, the higher the price is relatively conventional magnetic magnet, mainly used in food processing, new energy materials, carbon black, graphite, fine chemical processing industries. Customers can use Gauss meter (Tesla) magnetic magnet periodic testing, during use, pay attention to the use of temperature can not exceed the rated temperature, it will be very easy to accelerate magnet magnetic decay.
