Pole pitch of the magnetic separator magnetic separator equipment has an important role and significance

Magnetic Separator pole pitch for magnetic separator equipment has an important role and significance, although we

are talking about from the effect of the production efficiency of the magnetic separator is obvious and

, But for most who do not know much about the magnetic separation equipment, may not understand.
There's a reason, so Kefan magnetic separator manufacturers absolutely necessary to carry out the necessary

introduction to help friends want to know. Affect the magnetic separation mainly due to

Su is the magnetic field and the pole pitch practical results show that, along with the particle size of the change in

composition of the top field when the magnetic separator are different, as the particle size increases, the magnetic field

required

Intensity; With the particle size of the change in composition of the top pole magnetic separator from the type required in

the magnetic separator; as the particle size increases, also increases the pole pitch.Neodymium Arc Magnets Magnetic Separator

The maintenance magnechuck and safety instructions

Maintenance and safety instructions
  The electromagnetic chuck shall not serious bump, so as not to undermine the accuracy, idle, wipe oiled.cylinder magnets
The electromagnetic chuck enclosure should be grounded to avoid leakage wounding
The electromagnetic chuck perform standard: JB / T 10577-2006 magnechuck.

How do we judge no magnetic force of the magnetic chuck

Encounter this problem, you must first determine the electromagnetic chuck and the machine connected

demagnetization controller is not damaged, if there is no damage, then the workpiece on magnechuck

Surface, pay attention here, to step onto the pole more than two demagnetization controller magnetization, overband magnetic separator magnetic

How to control the temperature of the permanent magnet sucker grinding?

 The design and selection of the permanent magnet sucker requirements into account, the sucker in the

corresponding frequency range, to meet the load requirements attenuation characteristics, if a filter failure

Reductions can not meet the requirements of the alerts, and can adopt multi-cascade, can be obtained higher

attenuation than a single stage, the type of filter cascade can be obtained in a wide frequency band within good

Attenuation characteristics. So, how to control the temperature of the permanent magnet sucker grinding it?Magnetic Grid
   Permanent magnet sucker grinding process is often too late to pass in the depths of the workpiece, which gather the

formation of local high temperature in the surface layer. Workpiece surface temperature is often up to 1000 (in Table

The surface layer is formed great temperature gradient (up to 600 1000 [/ mm). Permanent magnet sucker grinding the

thermal effects village workpiece surface quality and performance a great impact.

Especially when the temperature at the interface exceeds a critical value, it will cause thermal damage of the table turns

(surface oxidation, burn, residual stress buckle crack). As a result will lead to

Parts of the anti-wear performance degradation, increased sensitivity to stress corrosion, fatigue resistance

deteriorates, thereby reducing the service life and the reliability of the permanent magnet sucker Part. Furthermore,neodymium block magnets

Accumulated temperature rise of the workpiece in the permanent magnet sucker grinding cycle, often leads to the

workpiece shape accuracy error of dimensional accuracy.
   Other -, the grinding heat of grinding zone, not only affect the workpiece, but also affect the life of the permanent

magnet sucker wheel. Thus, approximately the temperature in the grinding zone on the workpiece

Distribution, study of the permanent magnet sucker grinding wheel the effective abrasive grinding zone temperature to

study the distribution characteristics of the grinding burn before and after cutting temperature, is the study of the

grinding machine

Management and improve the integrity of the important issues of the grinding surface of the part.

The extensive use of the permanent magnet sucker

Permanent magnet sucker, also known as magnetic chuck or permanent lifting, machinery factory, mold factory, forging

plant, steel mills, shipyards, steel place the necessary handling tools,

In order to greatly improve the massive, cylindrical, plate, irregular guide the conveying efficiency of the magnetic steel

material. Permanent magnet sucker is a high-performance NdFeB rare earth materials (N> 40)

Kernel,Neodymium Arc Magnets pulled by hand rotation of the suction cup handle, change the sucker internal NdFeB magnetic system, to hold

or release the suction of the need to move the workpiece.
In our machining, mold manufacturing, metallurgical and other industries, some bulky steel or iron, steel processing

accuracy requirements or surface roughness of finished or semi-finished

Goods lifting, they use a wire rope bundled lifting, or also useful for lifting electromagnet electromagnet large volume,

high cost, failure and more difficult to maintain,magnetic separation

Electromagnet at work to consume a lot of power, a power failure, accident-prone. With the advent of high-performance

NdFeB rare earth materials, the use of Nd-Fe-B permanent magnet materials

Become a trend in the development of magnetic tools, permanent magnet sucker came into being.

The following reasons causing the problems

To excessive mine sieve overload, sieve working conditions can not meet the requirements, the sieve fraction high

levels of qualified, high-frequency fine sieve plant production capacity of high-frequency fine sieve expectations are too

high, according to the production capacity of the production factory calibration or exceed its production capacity to the

mine make the problem even more serious;
   Second, to the mine site design is not quite reasonable, resulting in excessive wear and tear to the mine site,

reducing the life of the screen; screen material, but off. Should be to improve the quality of efforts to guarantee the

accuracy of direction.overband magnet

     Sorting operations Problems processing plant workers and the efforts of the manufacturers, the domestic magnetic

separation equipment made some progress, but there is a great distance away from the magnetite process. Barrel
