effective utilization of resources slag magnetic separator magnetic effect

Slag magnetic separator magnetic mineral particles only after magnetic separation. Weakly magnetic minerals and the ferromagnetic minerals due to its chemical composition and crystal structure is different, it is different from the magnetization characteristics

Composed of many magnetic domains, according to market forecasts, our magnetic separator when the 2008 market size of about 11 million, in 2009, China's coal mining and washing industry, the total size of the construction

An increase of 53.1%, 84.4% of the net increase in built size, showing a strong momentum of growth. If the reduced magnetization H, J magnetization decreases compared, but not along the

The original curve, but is magnetic lifter decreased along the curve than the original, if the magnetizing field strength H is reduced to zero, J does not drop to zero, while retaining a certain value Jr, the number of

Value is called remanence, a phenomenon known as hysteresis, J in order to reduce to zero, and needs a reverse magnetic field, the strength of the coercive force Hc is called.

According to various minerals than the susceptibility differences, and different magnetic field strength slag separator machine, generally divided into three categories. Weakly magnetic minerals than the magnetic

Coefficient of 15 - 500 * 10-6 cm 3 / g, such as hematite, limonite, and other methods using magnetic separation recovery. Strong magnetic minerals than the susceptibility greater than 3000 * 10-6

Cm 3 / g, such as magnetite, pyrrhotite, etc., with a weak magnetic separation equipment that is able to effectively separate and gangue minerals. Magnetic minerals than the susceptibility of 500 -

3000 * 10-6 cm 3 / g, such as semi-illusion hematite and ilmenite, etc., with the magnetic field magnetic separation equipment for sorting.

Slag separator Henan Yu Fa Machinery Co., Ltd. is slag beneficiation designed magnetic separation equipment, mineral processing equipment for slag traditional screening inadequate Yu licensing

Slag separator greatly improved the appearance of slag screening efficiency, improve the efficient use of resources, but also by users unanimously approved, are detailed below under the slag magnetic

Sorting machine should be noted that the use of the principles and maintenance measures:

⊙ focus associated with the magnetic machine before and after the device task conditions, especially in front of weakening, slag and other operations must be running. Timing replace oil.

⊙ dielectric plate pleaded not string is not blocked, adhere cleaned once 20 to 30 days, regular replacement dielectric plate (for example, one year or six months depending on the condition of the tooth plate abrasion), and focus on pressure

Cover screws to tighten.

⊙ task focused oil and cooling oil temperature rise is too high to be reported to the workshop director, in order to adopt the necessary measures, such as downtime. Gearhead temperature super-

Limit should immediately report the workshop leader, parking View disposition.

⊙ focus on investigating the oil pressure gauge, pressure gauge, voltmeter, ammeter pointer whether sensitive reading ability to meet requests, identify problems and timely disposal to find relevant personnel

.

The so-called slag separator working gap, that is the spacing of the cylinder and the tank. This spacing is the size of concentrate quality factors affecting choose another one. If the slag machine

The gap is too small, that tube skin and too close to the tank, the slurry flow through only did he not affect the processing capacity, and because space is too small, it will make regardless of the size of the magnetic

Particles will get ample opportunity to breathe drum skin. Mainly due to the magnetic field from the pulp is too close, the magnetic field caused by the high strength. However, to reduce tailings grade increase the recovery rate

Is good.

If the spacing is too large, can only make a strong magnetic pick up particles, weaker on the election does not come up, although concentrate grade, but also increases the tailings grade

, Reducing recovery. Therefore, adjust the working gap slag machine is very important. Field production will generally need to be adjusted according to the working gap in the range of 35-60 mm

, The working gap angle bracket can be adjusted to change the bottom gasket gap size.
