Magnetic Separators

Magnetic Separators

The principle of magnetic separation is to selectively separate magnetic particles from a mixture with other non-magnetic particles based on the size and magnetic properties of the particles.

  • Application: Separation of metal minerals: hematite, limonite, siderite, ilmenite, chromite, wolframite, tantalum niobium ore, iron ore;Iron removal and purification of non-metallic minerals: feldspar, zircon, quartz, fluorite, spodumene, kaolin, tourmaline, garnet; or recovery of iron from beach sand.

Magnetic Separators Supplier

 ZONEDING is a magnetic separator manufacturer with more than 38 years of experience, with a variety of types to choose from, including wet, three-disc dry, high-intensity, flat-plate magnetic separators, etc. Magnetic separation is widely used in various industries to separate magnetic and non-magnetic materials. Magnetic separation equipment effectively removes unwanted ferrous contaminants from raw materials. Improves the recovery rate of high-purity and quality finished products in mining, providing an efficient and environmentally friendly solution for separating ferrous from non-ferrous materials. Versatile and can be customized to meet specific operational needs.

Working Principle Of Magnetic separators

The pulp flows into cell body from the pulp box, and under the water flow of the feeding spray pipe, the mineral grain will go into the feeding area of the cell body in the loose condition. In the magnetic field, the magnetic ore particles will have magnetic gathering and form magnet group or magnet chain which is influenced by the magnetic force inside the pulp and moves to the magnetic pole and finally is absorbed onto the cylinder.

Types of magnetic drum separators

  • Wet magnetic drum separators
  • Dry magnetic drum separators

Magnetic drum separators are divided into dry magnetic drum separators and wet magnetic drum separators.

Advantages of dry magnetic drum separators

  • No water requirement: Dry magnetic drum separators operate without a liquid medium, making them convenient and cost-effective. They are particularly advantageous in situations with limited water availability or a focus on water conservation.
  • Versatility: By adjusting magnetic field strength, drum speed, and other parameters, dry magnetic drum separators can process various minerals including iron ore, chromite, garnet, tantalite, and other magnetic minerals.
  • Easy maintenance: Dry magnetic drum separators generally have simpler designs and fewer components compared to wet separators, resulting in easier maintenance and lower maintenance costs.

Advantages of wet magnetic drum separators

  • Full magnetic design shows large contact area between the pulp and the effective working surface.
  • The magnetic content of tailings is significantly reduced, which is 1–3% lower than that of ordinary magnetic separation equipment.
  • The separating process is lengthened to make concentrate grade increase by 2–4%.
  • They can process varying slurry densities, feed rates, and particle sizes without compromising separation performance. This makes them suitable for operations with fluctuating feed characteristics.
  • They can be easily integrated into existing mineral processing circuits like grinding and classification circuits to enhance the overall efficiency of the mineral processing operation.
