Magnetic Separator

The magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size of 3mm or less. It is also used for iron removal of coal, non-metallic minerals, building materials and other materials.

The magnetic system of the magnetic separator is made of high-quality ferrite material or composited with rare earth magnet steel. The average magnetic induction intensity of the cylinder table is 100-600 mT. According to the needs of users, we can provide magnetic separators with different surface strengths such as downstream, semi-backflow and counterflow. The product has the advantages of simple structure, large processing capacity, convenient operation and easy maintenance.

The magnetic separator is a device that separates the magnetic substances in the mixture by magnetic force and mechanical force by utilizing the difference in the specific magnetic coefficients of various minerals. According to different working modes, it can be divided into dry magnetic separator and wet magnetic separator.

   

Know more about FDM Magnetic separator

 

1. A wide range of applications. Used in coal mines, foundry sands, refractory materials, and other iron removal operations required in other industries.

2. Good magnetic separation performance. Compared with the conventional magnetic separation equipment, the magnetic separator adds high-performance permanent magnets to the magnetic structure design to ensure that the magnetic properties are not lost under high flow conditions.

3. The quality of the product is high. Used in the ceramic industry to remove the mixed iron in the porcelain mud and improve the quality of the ceramic products.

4. Save resources. For the hematite reduction closed-circuit roasting operation, the raw ore that is not fully reduced is sorted and returned to re-burn.

 

Working principle

 

After the slurry is fed into the tank by the ore tank, the ore particles enter the tank feeding area in a loose state under the action of the water flow to the mine sprinkler pipe. In the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a “magnet” or “magnetic flux”. The “magnet” or “magnetic flux” is magnetically applied to the magnetic pole, moves toward the magnetic pole, and is adsorbed on the cylinder.

Since the polarities of the magnetic poles are alternately arranged in the direction of rotation of the cylinder, and are fixed during operation, the “magnet” or “magnetic flux” is magnetically agitated due to the alternating magnetic poles when being rotated with the cylinder, and is mixed. The non-magnetic minerals such as gangue in the “magnet” or “magnetic flux” fall off during the flipping, and the “magnet” or “magnetic flux” that is finally attracted to the surface of the cylinder is the concentrate. The concentrate passes to the weakest point of the magnetic system at the edge of the magnetic system, and is discharged into the concentrate tank under the action of the flushing water jet discharged from the unloading water pipe. If it is a full magnetic magnetic roller, the unloading is performed by a brush roller. Non-magnetic or weakly magnetic minerals are left in the slurry with the slurry exiting the trough, which is the tailings.
