The dry magnetic separator is a commonly used iron ore equipment and manganese ore equipment, and the mainstream strong magnetic separator ore dressing equipment.
Introduction of dry magnetic separator: Dry magnetic separator is a magnetic beneficiation machine for sorting dry magnetic minerals. Compared with wet magnetic separator, when using minerals as diluent to improve sorting efficiency, dry The magnetic separator requires that the sorted minerals be dry, and the particles can move freely and become independent free states, otherwise the magnetic separation effect will be affected, and even the result of unsortability may be caused. The dry 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 dry 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, it can provide magnetic separation of many different surface strengths such as downstream, semi-reverse flow and counterflow. The magnetic separator has the advantages of simple structure, large processing capacity, convenient operation and easy maintenance.
Dry magnetic separator application range:
This series of dry magnetic separator is suitable for refractory materials, chemical materials, grain and oil machinery, abrasives, ceramics, metallurgy, cement, powder metallurgy, rubber, ore and other materials, except for (optional) iron, and can be used with Raymond mill. , pulverizer, ball mill for use. Dry magnetic separator features: It 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 the removal of coal, non-metallic minerals, building materials and other materials. Iron work. The magnetic system of the dry magnetic separator is made of high-quality ferrite material or composited with rare earth magnet steel. The average magnetic induction intensity of the cylinder is 100~600mT. The dry magnetic separator has a simple structure, large processing capacity, convenient operation, and easy maintenance.
Dry magnetic separator works:
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 spout. In the role 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 and moves toward the magnetic pole, and is adsorbed on the cylinder. . The dry magnetic separator is alternately arranged in the direction of rotation of the cylinder due to the polarity of the magnetic poles, and is fixed during operation. When the "magnet" or "magnetic flux" rotates with the cylinder, magnetic is generated due to the alternating magnetic poles. Stirring phenomenon, non-magnetic minerals such as gangues entrained in "magnet" or "magnetic flux" fall off during the flipping, and the "magnet" or "magnetic lotus" that is finally sucked on the surface of the cylinder is the concentrate. . The concentrate of the dry magnetic separator moves 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 sprayed from the unloading water pipe. If it is a full magnetic magnetic roller, the unloading is Made with a brush roller. Non-magnetic or weakly magnetic minerals are left in the slurry with the slurry exiting the trough, which is the tailings. Reference: http://
