What are the main classifications of magnetic separation equipment

Magnetic separation equipment is a machine that uses different materials based on mineral magnetism, and its main equipment is a magnetic separator. The magnetic separation equipment is suitable for screening a variety of magnetic minerals, such as Ilmenite, Limonite, manganese Siderite, Pyrrhotite, Ilmenite, Wolframite, metallurgical manganese ore, manganese oxide ore, iron ore, kaolin, rare earth ore, etc. So what are the main classifications of magnetic separators for magnetic separation equipment?

Classification of magnetic separators

According to the different types of magnets, they can be divided into permanent magnet magnetic separators and electromagnetic magnetic separators. According to the different dryness and wetness of the processed materials, they can be divided into dry magnetic separators and wet magnetic separators; There are also disc magnetic separators, plate magnetic separators, and other classifications for magnetic separators.

Dry magnetic separators mainly screen dry magnetic materials, unlike wet magnetic separators that require diluents when sorting materials. The dry magnetic separator requires the materials to be selected to be dry and dispersed, with gaps between particles to improve sorting efficiency. The dry magnetic separator is suitable for sorting coarse particles, with a maximum size of 30-50 millimeters. The finished product can be stored without dehydration. The dry magnetic separation process has simple design, convenient operation, and fewer sorting steps, greatly saving time and cost. However, it also has its own limitations, that is, it is not suitable for screening moist and fine-grained materials.

Wet magnetic separator

The slurry of Limonite, manganese Siderite, etc. flows into the magnetic separator tank and enters the mining area in a loose state. Under the magnetic force of the magnetic separation equipment, the magnetic ore particles form a "magnetic cluster" or "magnetic chain", which moves towards the magnetic pole under the magnetic force and is adsorbed on the cylinder. Due to the alternating polarity of the magnetic poles along the direction of rotation of the cylinder, they are fixed during operation. When the "magnetic cluster" or "magnetic chain" rotates with the cylinder, magnetic stirring occurs due to the alternating magnetic poles. Non magnetic particles mixed in the "magnetic cluster" or "magnetic chain" separate during the rotation process, and finally the "magnetic cluster" or "magnetic lotus" sucked into the surface of the cylinder is fine iron ore. The refined iron ore rotates with the cylinder to the point where the magnetic force at the edge of the magnetic system is weakest, and is unloaded into the concentrate tank under the action of water flow. Non magnetic or weakly magnetic minerals remain in the slurry and are discharged from the tank along with the slurry, known as iron tailings.

High gradient magnetic separator

High gradient magnetic separation can generate strong magnetic force, suitable for screening particle sizes less than 20 μ Fine grained material of m. That is to say, the metal materials in iron tailings can be recycled with high yield, obtaining high-quality iron, and also reducing the grade of tailings to a certain extent, making them more popular among users.
