drum magnetic separator - Classification

Magnetic separator can be divided into low magnetic field intensity magnetic separator, the magnetic separator, high magnetic separator; generating a magnetic field in accordance with a method can be divided into electromagnetic and permanent magnetic separator

Magnetic separator; accordance with the structure can be divided into different disc, drum, roller, ring, drum, transfer cage and belt magnetic separator; sorting methods can be divided by the dry and wet

Magnetic separator.

Can be divided into suspension magnets downstream magnetic separator and semi-countercurrent separator:
Downstream permanent magnet drum magnetic separator, the slurry moving direction or the direction of rotation of the cylindrical products moving in the same direction. Slurry from the tank to the mine directly into the cylinder below the magnetic system

Non-magnetic mineral particles and the magnetic mineral particles weak bottom by a cylindrical gap between the bottom two discharge. Magnetic mineral particles stick on the cylinder surface, the cylinder rotates together with the magnetic

Department at the edge of the magnetic field is weak, the mine water discharge be landed to concentrate tank. Downstream magnetic machine structure is simple, processing capacity, can be used more than one series, suitable for

Choice of granularity is 6 ~ 0mm strong magnetic ore coarse roughing and operations, or for the recovery of the magnetic heavy media. Semi-countercurrent permanent magnet drum magnetic separator, to ore slurry is

A loosely suspended from the bottom of the tank into the separation space, pulp movement direction and the direction of the magnetic force is basically the same, so the mineral particles can reach very high magnetic forces round

Cylinder surface. N52 magnet In addition, the tailings from the tailings discharge hole on the bottom, so that the height of the overflow surface can be maintained in the slurry tank level. The above two features, must

Given half a counterflow separator to receive a higher quality of concentrate and metal recovery. It is widely and to handle micro-fine (less than 0.2mm) thick ferromagnetic ore

Selection and selection operations. This separator can be more than one series, and raise the concentrate grade.

the protection of dry magnetic separation machine, replacing the screen trilogy

  In constant exploration, dry magnetic separator has been rapid development, but also faces competition within the industry, in today's sluggish economy, and only through innovation development

To occupy a foothold in the market, we can achieve good survival and development. Magnetic mechanical processing equipment machinery has been committed to research in this market

A large market value, Grate Magnet  has its own characteristics, but he also continues to develop, innovation. Only continue to move forward, in order for the enterprise

Fresh blood in the footsteps of history in order to Liu Yong Jin. Dry magnetic separator in terms of quality there is still much room for improvement, processing equipment Industrial is committed to creating belong

Own brand, to create a consumer of good equipment, but also the only way to make their own continued to mature.
    As we all know, processing equipment installed inside mesh according to various models for all sorts of different machines all have different roles, so the choice is one thousand poor Wan

Do not have different, then select its characteristics and skills above, you have captivated focus. The most common mistakes novice is to pick a mesh accessory, only

Is simply based on the price to buy the equipment to consider, that the high price is good, but does not know the right is the best.
    Moreover, the high price of the screen, where although the quality is quite good, but optimization of production costs, but the effect is not high, there is inappropriate sieve

Network, will cause difficult to repair, the worse thing is the change down again is not installed, can not be used more because of inappropriate waste. This is the whole question of mineral processing equipment

Questions, then specific to the separator above it? Industry today will explain it for everyone here, but still want to separate, magnetic separator today highlight some issues, application

In the separator on the screen, replacing the need to pay attention to three requirements, they are:
    First, when the dry magnetic separator sieve after the problem has occurred, this side has produced mineral aggregate, must be separated again, because it may at their request

Did not pass, and if simply select it gone, and will definitely cause problems. Second, if you want drum separator to achieve economies of production, then the separator screen appears damaged

The case is not about to throw away, you can use three additional rivet welding nozzle to fill well. Finally, we get a new screen films, pay attention to positive and negative, often operating workers

Are not considered to have pros and cons of the points, it is not true, shag Asari, glossy outward is the best design.

dry magnetic separator related equipment

Wet permanent magnet drum magnetic separator iron ore concentrator is widely used as a separator, it applies to the sorting strong magnetic minerals.

Wet drum magnetic separator magnet structure is divided into downstream accordance tank, counter-style, semi-countercurrent three.

Wet Drum Magnetic magnetic bar Separator in permanent magnetic separation plant outside except as sorting devices, in recent years also used as a filter in front of enrichment equipment to replace the magnetic dewatering tank.

Many different types of strong magnetic separator, according to operating conditions are divided into wet and dry; divided by the magnetic source electromagnetic and permanent magnet; press the device structure is divided into disc, roller,

Flat ring, ring stand, sensor roller and so on.
