Know Before purchase magnets

1. rare earth grate magnet specification size (diameter and length)
2. Surface GS strength (generally done 6000-12000GS)
3. Temperature requirements (usually the default is at room temperature, if the conveyor magnet will work in high temperatures, advance instructions)
4. Number demand
5. Other special requirements (such as threaded holes at both ends need to add)
6. The drawings are not conventional shape can be customized

Magnetic filter use:

Pipeline magnetic filter is mainly used to remove liquid slurry ferromagnetic impurities, widely used in chemical, pharmaceutical, pigments, dyes, food, metallurgy, ceramics and other industries, this product has a strong magnetic force, in addition to the effect of good iron, iron cleanup and easy. In addition to iron magnetic filter is mainly used for small viscosity of the liquid, can remove small particles 0.5 ~ 60μm naked eye can not see. Suitable for removing food (syrup, jam, fruit juice, cooking oil, etc.); chemicals (paints, lubricating oil, cutting oil, dye, syrup industry, pulp, brine, etc.) mixed in a high concentration of liquid iron and other magnetic impurities. The magnetic source is made of high-performance strong performance bar magnetsmaterials, magnetic stirring bar set force than comparable conventional magnetic material (ferrite or alnico permanent magnet material) is 5-20 times higher magnetic force. Secretary of the production of magnetic products up 12000GS, service life of 10 years. Surface finish rod magnets can reach 400 mesh, suitable for food-grade requirements.

Magnetic filter works:

In the liquid slurry transportation process, the slurry through a filter, that is a powerful magnet magnetic filter bars action, the slurry of iron impurities are adsorbed on the magnet sleeve, the elimination of slurry of iron impurities, guarantee the next process can effectively control the iron impurities.

In addition to the separator magnet for the iron work unit selection using the knowledge

1. Replace the standard
Common standards within the industry: select Replace when less than 80 gauss magnet magnetic force.
2. Procurement Standards
Purchasing magnet, the best buy magnetic high, and the current level of 12,000 Gauss 25mm diameter can be done, because the magnet's magnetic force will naturally decline, (if there is a family commitment not demagnetization, absolutely anti-scientific, but different quality, recession different speeds), when purchasing a magnetic filter bar table is higher, service life is longer.
3. Routine Maintenance
To avoid demagnetization magnet to accelerate and ensure the safety of materials in daily use, you need to do the following:
a), promptly clean up the magnet surface of the metal impurities;
b), do not over-rated service temperature (responsible supplier will be stated in the quotation, different temperature, a lot of) the cost difference;
c), using the process to avoid the bump, altitude fall;
d), not used in the warehouse, try to stay away from ferromagnetic materials.
4. magnetic bar sets monitoring
Magnet type separator and more manufacturers use parity, the best self-testing tools, testing tools commonly used suction tester and gauss meter, test instrument is relatively simple suction operation, visual indication of the two instruments domestic prices in One thousand little more. By using load magnet is not the case, three months can be tested once. Preparation of an instrument, when you can purchase Separators inspection available.

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.
