Work Process

  • Generation of magnetic field
    The magnetic field in a slurry magnetic separator is usually generated by an electromagnet. By energizing the electromagnet, the intensity and direction of the magnetic field generated by the electromagnet can be adjusted to adapt to the magnetic sorting needs of different particles. In addition, some high-performance permanent magnets can also be used to generate stable magnetic fields, which have the advantages of energy saving and environmental protection.
  • Sorting of magnetic particles
    When the slurry passes through the magnetic field, the magnetic particles are affected by the magnetic force and are adsorbed in the magnetic pole area to form magnetic ore; the non-magnetic particles are repelled to the edge of the magnetic field and form a non-magnetic waste residue. By adjusting the intensity and direction of the magnetic field, the trajectory of magnetic particles can be controlled, thereby achieving effective sorting.


As an advanced technology that uses magnetic fields for material separation, electromagnetic slurry magnetic separator has broad application prospects. In the fields of mining, environmental protection, and waste treatment, it will play an important role in improving resource utilization and reducing environmental pollution. With the continuous development of science and technology, we believe that electromagnetic slurry magnetic separators will show their strong application potential in more fields and contribute to the sustainable development of mankind.


How to Select Slurry Magnetic Separator?

When selecting a slurry electromagnetic separator, certain principles need to be followed to ensure that the selected equipment can meet production needs and process requirements. The following will introduce the principles of slurry electromagnetic separator selection in detail.

1. Understand the characteristics of slurry

Before choosing a slurry electromagnetic separator, you need to understand the characteristics of the slurry. This includes the slurry’s concentration, viscosity, solids content, particle size, etc. These characteristics will directly affect the selection and design of the separator.

2. Determine processing capacity

Based on production needs, determine the amount of slurry that needs to be processed. This will determine the size and power requirements of the separator. When selecting a separator, you need to ensure that it can meet the processing capacity requirements of the production line.

3. Choose the appropriate magnet

The magnetic force of the slurry electromagnetic separator is the key factor affecting the iron removal effect. When choosing a separator, you need to understand its magnetic force and magnetic field strength. Generally speaking, high magnetic force can better adsorb and remove iron impurities in the slurry. However, too high a magnetic force may lead to increased energy consumption and wear and tear of the equipment, so it is necessary to select the appropriate magnetic force based on actual needs.

4. Consider equipment structure

The structure of the slurry electromagnetic separator is also an important factor in model selection. It is necessary to select an equipment structure suitable for the characteristics of the slurry to ensure iron removal effect and equipment durability. Generally speaking, the slurry electromagnetic separator should be wear-resistant, corrosion-resistant, and easy to clean and maintain.
