Magnetic Separator for Mineral Separation and Iron Removal

Magnetic Separator

Magnetic Separator is widely used for separating magnetic minerals and removing iron impurities from various materials. According to different processing requirements, magnetic separators can be divided into dry magnetic separators and wet magnetic separators. They are suitable for magnetic separation of magnetite, pyrrhotite, ilmenite, roasted ore and other materials, as well as iron removal in coal, non-metallic minerals and building material industries.

Efficient Magnetic Separation – Suitable for magnetite and magnetic minerals
Dry and Wet Types – Available for different material handling requirements
Iron Removal Applications – Used in coal, minerals and building materials processing

The magnetic separator can separate the different magnetic substances, which is one of the widely used and high universal machines in the industry. The magnetic system of our company’s magnetic separator is made of high-quality ferrite material or composite with rare earth magnetic steel, which has the advantages of simple structure, large processing capacity, convenient operation, easy maintenance, etc.

Application Scope

There are many minerals that can be separated by the magnetic separator, such as magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate ore, manganese ore, manganese oxide ore, iron ore, kaolin, rare earth ore, etc., which can be separated by the magnetic separator.

Advantages of Fodamon high strength magnetic separator

1. According to the user’s needs, it can provide a variety of magnetic separation with different surface strengths, such as forward current, half reverse current and reverse current. The high strength magnetic separator has the advantages of simple structure, large processing capacity, convenient operation, easy maintenance, etc.
2. The semi countercurrent tank is suitable for the wet roughing and cleaning of the strong magnetic minerals with the particle size of 0.5-0mm, especially for the cleaning of the large minerals with the particle size of 0.15-0mm.
3. Countercurrent tank is suitable for wet roughing and sweeping of 0.6-mm strong magnetic minerals. Especially suitable for heavy medium recovery in coal washing plant.
4. The downflow tank is suitable for the roughing and cleaning of ore with particle size of 6-0mm.
5. Semi countercurrent tank and downstream tank can be used in series to improve concentrate grade.
6. The equipment has super high wear resistance and high temperature resistance, very reliable quality, super high output, and the magnetic separation efficiency is more than three times that of the ordinary magnetic separator.

Working principle

After the pulp flows into the tank through the ore feed tank, under the action of the water flow of the ore feed spout pipe, the ore particles enter the ore feed area of the tank in a loose state. Under the action of magnetic field, the magnetic ore particles gather to form “magnetic group” or “magnetic chain”. The “magnetic group” or “magnetic chain” moves to the magnetic pole under the action of magnetic force in the pulp and is adsorbed on the cylinder. Because the polarity of the magnetic pole is alternately arranged along the rotation direction of the cylinder, and it is fixed when working, “magnetic mass” or “magnetic chain” is rotating with the cylinder, the phenomenon of magnetic agitation occurs due to the alternation of the magnetic pole, the gangue and other non-magnetic minerals mixed in the “magnetic mass” or “magnetic chain” fall off during the turning, and finally are absorbed in the “magnetic mass” or “magnetic Lotus” on the cylinder surface. The concentrate is transferred to the weakest magnetic field at the edge of the magnetic system along with the cylinder, and is discharged into the concentrate tank under the action of flushing water from the ore discharge pipe. Nonmagnetic or weak magnetic minerals are left in the slurry and discharged out of the tank with the slurry.

Magnetic Separator Technical FAQ

Q1: How do I choose between a wet and dry magnetic separator?
A: It depends on your material’s particle size and processing requirements. Dry magnetic separators are typically used for coarse-grained, strong magnetic minerals, while wet magnetic separators are better for fine-grained minerals to ensure higher separation efficiency and prevent dust pollution.

Q2: What is the maximum magnetic field intensity of your equipment?
A: We offer a range of magnetic separators from low intensity (1,000-3,000 Gauss) to high-gradient intensity (up to 12,000-15,000 Gauss). Our engineers will recommend the most suitable intensity based on your specific ore’s magnetic properties.

Q3: How do you prevent the magnetic drum from wearing out quickly?
A: Our drums are covered with a high-quality rubber wear-resistant layer or stainless steel protective shells. This significantly reduces the direct impact of abrasive mineral ores on the magnetic system, extending the service life by more than 30%.
