1. Basic introduction of magnetic separator

Magnetic separator is used to remove iron powder etc. from reusing powdery granules. Magnetic separator is widely used in resource recovery, wood industry, mining industry, kiln industry, chemical industry, food and other factories. Wet magnetic separation of iron ore, pyrrhotite, roasted ore, ilmenite and other materials, and also used for iron removal of coal, non-metallic ores, building materials and other materials, is the most widely used and highly versatile in the industry. One of the models.

Magnetic separator is one of the most widely used and highly versatile models in the industry, and is suitable for the separation of substances with magnetic differences. The magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, hematite and other materials with a particle size of less than 50mm. It is also used for non-metallic ores and building materials. Iron removal of other materials. Magnetic separators are divided into electromagnetic magnetic separators and permanent magnetic separators. The magnetic system of permanent magnetic separators is mostly made of high-quality ferrite materials or composited with rare earth magnetic steel. The average magnetic induction intensity on the surface of the machine magnetic cylinder is 80-400mT. With the continuous development of technology, after the magnetic separator can be made into a roll shape, the magnetic field intensity is also increased to 1650mT, which is the highest magnetic field intensity measured by the permanent magnet magnetic separator at present. Compared with the permanent magnet magnetic separator, the electromagnetic magnetic separator has stronger magnetic flux and often has a better effect. However, because of its electromagnetic nature, power consumption, vulnerability, and difficulty in maintenance, companies with low budgets have invested in permanent magnets.

3. Working principle of magnetic separator

After the ore slurry flows into the tank body through the ore feeding box, under the action of the water flow of the ore feeding water spray pipe, the ore particles enter the ore feeding area of the tank body in a loose state. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a "magnetic cluster" or "magnetic chain". . Since the polarities of the magnetic poles are alternately arranged along the rotation direction of the cylinder and are fixed during operation, when the "magnetic group" or "magnetic linkage" rotates with the cylinder, magnetic stirring is generated due to the alternation of the magnetic poles, and is mixed with The non-magnetic minerals such as gangue in the "magnetic cluster" or "magnetic chain" fall off during the tumbling, and the "magnetic group" or "magnetic chain" that is finally attracted to the surface of the cylinder is the concentrate. The concentrate moves with the cylinder to the edge of the magnetic system where the magnetic force is the weakest, and is discharged into the concentrate tank under the action of the flushing water flow from the discharge pipe. Non-magnetic or weakly magnetic minerals are left in the pulp and discharged out of the tank with the pulp, that is, tailings.
