10,000 Gauss High Intensity Magnetic Separator | Iron Ore/Scrap Metal/Quartz Sorting | Dry & Wet Type Customizable.
1. Working Principle
High - intensity magnetic separators are designed to separate magnetic and non - magnetic materials based on their different responses to a strong magnetic field. These separators generate extremely powerful magnetic fields, either through high - power electromagnets or advanced permanent magnet assemblies.
When materials, which can be in the form of dry powders, slurries, or granular substances, pass through the magnetic field zone of the separator, magnetic particles within the material are strongly attracted to the magnetic source. The force exerted on these magnetic particles is significantly greater than the forces acting on non - magnetic particles, such as gravity, fluid drag, or electrostatic forces. As a result, magnetic particles deviate from their original paths and are collected, while non - magnetic particles continue to move along with the main flow stream. This clear differential behavior enables efficient separation of materials with varying magnetic susceptibilities.
2. Structural Features
- Powerful Magnetic Assembly:
- In electromagnet - based high - intensity magnetic separators, large - sized coils wound around high - permeability magnetic cores are used. These coils are connected to high - voltage and high - current power supplies to generate intense magnetic fields, often reaching several teslas. Cooling systems, such as water - cooling or air - cooling mechanisms, are integrated to dissipate the heat generated during operation and maintain the stability of the magnetic field.
- Permanent - magnet - type high - intensity magnetic separators utilize rare - earth permanent magnets, like neodymium - iron - boron magnets. These magnets are arranged in specific configurations to create a concentrated and strong magnetic field. Their high coercivity and remanence properties ensure long - term stable magnetic performance without the need for continuous power input for magnetization.
- Separation Chamber: The separation chamber is where the actual separation process takes place. It is designed to provide an optimal space for materials to interact with the magnetic field. The chamber may have specific internal structures, such as baffles or flow - guiding plates, to control the flow rate and direction of the material, ensuring that magnetic particles have sufficient time to respond to the magnetic field and be separated effectively. In some models, a matrix of ferromagnetic elements, such as steel rods or wire meshes, is placed within the chamber. This matrix further enhances the magnetic field gradient, enabling the capture of even weakly - magnetic particles.
- Feeding and Discharging Systems:
- The feeding system is responsible for delivering the material to be separated into the magnetic field zone in a controlled and uniform manner. It can be equipped with devices like vibrating feeders or screw conveyors to adjust the feed rate according to the processing requirements. For slurries, specialized pumps are used to ensure a consistent flow.
- The discharging system consists of separate outlets for magnetic and non - magnetic fractions. The magnetic fraction is usually discharged through a mechanism that can handle the accumulated magnetic particles, such as a rotating drum or a vibrating chute. The non - magnetic fraction is discharged through a different outlet, often designed to prevent any cross - contamination between the two fractions.
