The slurry magnetic separator is magnetic separation equipment designed for wet mineral processing, used to extract magnetic minerals from liquid mineral slurries efficiently. Its core design is optimized for mineral slurries with high water content and can handle fine or highly fluid particles ranging from a few micrometers to several millimeters in size. They are widely applicable to tailings recovery in mineral processing plants, metal ore beneficiation, and non-metallic mineral purification. Especially in the removal of impurities from kaolin, feldspar, and silica sand, slurry magnetic separators can achieve magnetic mineral recovery rates of over 98%, directly improving the grade and added value of end products.
Slurry magnetic separators are high-gradient magnetic separation devices designed for liquid and slurry streams. Their core function is to use magnetic force to separate magnetic impurities from useful materials in the slurry. They can be used for the beneficiation and enrichment of ferrous metal minerals, as well as the purification of non-metallic minerals, chemical raw materials, and new energy materials. Examples include the wet beneficiation of strongly magnetic minerals such as magnetite, pyrrhotite, roasted ore, ilmenite, and vanadium-titanium magnetite; and the iron removal of non-metallic minerals such as kaolin, feldspar, quartz, and calcite. It significantly improves mineral whiteness and purity, reduces the loss of magnetic minerals in tailings, and increases mineral-processing recovery. It can be adapted to all scenarios, from laboratory-scale and pilot-scale tests to large-production lines with capacities of tens of thousands of tons.
The slurry magnetic separator can capture weakly magnetic iron oxide and mechanical iron impurities with particle sizes as small as 5 micrometers, achieving an iron removal rate of up to 99%, meeting the stringent purity requirements of multiple industries such as ceramics, lithium batteries, mineral processing, and chemicals. Compared with other magnetic separation equipment, slurry magnetic separators are suitable for hydrometallurgical processes and slurry processing, eliminating the need for additional drying or crushing and enabling direct connection to existing slurry-conveying pipelines. They are also among the most widely used and efficient iron-removal equipment in mineral processing and industrial purification.
Drive Unit:
Stepless speed regulation system of variable frequency motor + planetary reducer
Cooling System:
Oil-water composite cooling can quickly remove the heat generated by the excitation coil during operation, preventing the magnetic field strength from weakening.
Рама:
Composed of a carbon steel frame, a stainless steel shell, and sealing components, it meets requirements for use in harsh operating conditions, including outdoor and highly corrosive environments.
Flushing System:
A high-pressure water spray device removes impurities adsorbed on the magnetic poles, preventing blockage of the magnetic medium.
1. Ultra-high iron removal accuracy: It can capture weakly magnetic iron oxide impurities with a particle size of up to 2 micrometers, achieving an iron removal rate of up to 99.5%. This reduces the iron content of materials to below 0.01%, meeting the raw material purity requirements of high-end industries.
2. High adaptability: The electromagnetic slurry magnetic separator can flexibly adjust parameters such as magnetic field strength, feeding speed, and washing time according to the characteristics of the material, adapting to the separation needs of materials with different particle sizes and magnetic properties.
3. Low operating energy consumption:
Adopting a new excitation coil design and a high-efficiency cooling system, the energy consumption per ton of ore processed is 20%-30% lower than that of traditional equipment.
4. Fully Automated Operation:
Equipped with a PLC intelligent control system, it can automatically complete the entire process of ore feeding, magnetic separation, and ore unloading without manual supervision, resulting in low manual operation costs.
5. Strong magnetic field stability:
Using oil-water composite cooling technology, the coil temperature rise can be controlled to within 20℃, ensuring consistent sorting performance without magnetic-field attenuation over long-term operation.
6. Long lifespan of magnetic media: Contact components are coated with polyurethane or 316L stainless steel, which is highly wear-resistant, has low residual magnetism, and leaves no residual magnetic impurities after ore unloading. The normal service life can exceed 5 years, reducing consumable replacement costs.
The slurry magnetic separator operates based on the difference in coercivity of magnetic minerals. After the slurry is fed into the separation chamber by a feed pump, it is subjected to a high-gradient alternating magnetic field generated by a rotating magnetic roller. Magnetic particles are adsorbed onto the surface of the magnetic system and are then scraped off by scrapers as the magnetic roller rotates to the unloading area; non-magnetic minerals are discharged directly through the overflow trough.

The equipment can process ultrafine magnetic minerals with particle sizes as low as 5 micrometers. It is suitable for iron removal and purification of non-metallic minerals such as kaolin, feldspar, quartz, calcite, fluorite, and spheroidal clay. It is also suitable for wet enrichment of strongly magnetic minerals such as magnetite, pyrrhotite, roasted ore, ilmenite, and vanadium-titanium magnetite. It is particularly effective for iron removal and purification of kaolin and silica sand. Magnetic system parameters need to be customized according to the differences in the magnetic properties of the minerals.
For example, the optimal feed concentration for kaolin is 10-20%; for potassium and sodium feldspar, the range is 20-30%. Specific requirements depend on the type and characteristics of the slurry. If the slurry concentration is >40% or contains clay impurities, pre-dilution or desliming screening is recommended to prevent pipe blockage.
Yes, the magnetic field strength can be adjusted (15000-18000GS). It is recommended to determine the optimal strength through laboratory testing. Generally, weakly magnetic minerals require a higher field strength, which should be adjusted in conjunction with the rotation speed and washing water pressure.
Single unit capacity: varies from 10 to 100 m³/h. Modular combinations are suitable for small and medium-sized concentrators; for large projects, multiple units in parallel are recommended, requiring calculations based on ore grade, slurry flow rate, and other data.
Check the lubrication system daily and clean the magnetic cylinder monthly to remove impurities. Lubricate bearings every 6 months. Electrical components must be protected from moisture. For purchase inquiries, please contact our professional engineers.
Before selecting a model, you need to provide the type of material to be treated, particle size range, slurry concentration, current iron impurity content, expected performance after iron removal, and throughput requirements. We recommend conducting mineral sample analysis and separation tests first, and matching the most suitable magnetic field strength, magnetic media specifications, and equipment model based on the test results. We will also provide a corresponding process design solution to ensure that the equipment achieves the expected production results after being integrated into your existing production line.
The core difference between a slurry magnetic separator and a traditional magnetic separator lies in the magnetic field gradient and the material form they can handle. Traditional магнитные сепараторы have a low magnetic field gradient and can only capture large-particle-size, strongly magnetic impurities. In contrast, the high-gradient magnetic field of a slurry magnetic separator can effectively capture these weakly magnetic, fine impurities.
